s GENERAL DESCRIPTION
The MBM29F016A is a 16 M-bit, 5.0 V-Only Flash memory organized as 2 M bytes of 8 bits each. The 2 M bytes of data is divided into 32 sectors of 64 K bytes for flexible erase capability. The 8 bit of data will appear on DQ0 to DQ7. The MBM29F016A is offered in a 48-pin TSOP(I) package. This device is designed to be programmed in-system with the standard system 5.0 V VCC supply. A 12.0 V VPP is not required for program or erase operations. The device can also be reprogrammed in standard EPROM programmers. The standard MBM29F016A offers access times between 70 ns and 120 ns allowing operation of high-speed microprocessors without wait states. To eliminate bus contention the device has separate chip enable (CE), write enable (WE), and output enable (OE) controls. The MBM29F016A is command set compatible with JEDEC standard E2PROMs. Commands are written to the command register using standard microprocessor write timings. Register contents serve as input to an internal state-machine which controls the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the device is similar to reading from 12.0 V Flash or EPROM devices. The MBM29F016A is programmed by executing the program command sequence. This will invoke the Embedded Program Algorithm which is an internal algorithm that automatically times the program pulse widths and verifies proper cell margin. Each sector can be programmed and verified in less than 0.5 seconds. Erase is accomplished by executing the erase command sequence. This will invoke the Embedded Erase Algorithm which is an internal algorithm that automatically preprograms the array if it is not already programmed before executing the erase operation. During erase, the device automatically times the erase pulse widths and verifies proper cell margin. This device also features a sector erase architecture. The sector erase mode allows for sectors of memory to be erased and reprogrammed without affecting other sectors. A sector is typically erased and verified within 1 second (if already completely preprogrammed). The MBM29F016A is erased when shipped from the factory. The MBM29F016A device also features hardware sector group protection. This feature will disable both program and erase operations in any combination of eight sector groups of memory. A sector group consists of four adjacent sectors grouped in the following pattern: sectors 0-3, 4-7, 8-11, 12-15, 16-19, 20-23, 24-27, and 28-31. Fujitsu has implemented an Erase Suspend feature that enables the user to put erase on hold for any period of time to read data from or program data to a non-busy sector. Thus, true background erase can be achieved. The device features single 5.0 V power supply operation for both read and program functions. Internally generated and regulated voltages are provided for the program and erase operations. A low VCC detector automatically inhibits write operations during power transitions. The end of program or erase is detected by Data Polling of DQ7, or by the Toggle Bit I feature on DQ6 or RY/BY output pin. Once the end of a program or erase cycle has been completed, the device automatically resets to the read mode. The MBM29F016A also has a hardware RESET pin. When this pin is driven low, execution of any Embedded Program or Embedded Erase operations will be terminated. The internal state machine will then be reset into the read mode. The RESET pin may be tied to the system reset circuity. Therefore, if a system reset occurs during the Embedded Program or Embedded Erase operation, the device will be automatically reset to a read mode. This will enable the system microprocessor to read the boot-up firmware from the Flash memory. Fujitsu's Flash technology combines years of EPROM and E2PROM experience to produce the highest levels of quality, reliability, and cost effectiveness. The MBM29F016A memory electrically erases all bits within a sector simultaneously via Fowler-Nordheim tunneling. The bytes are programmed one byte at a time using the EPROM programming mechanism of hot electron injection.

s FUNCTIONAL DESCRIPTION Read Mode
The MBM29F016A has two control functions which must be satisfied in order to obtain data at the outputs. CE is the power control and should be used for a device selection. OE is the output control and should be used to gate data to the output pins if a device is selected. Address access time (tACC) is equal to the delay from stable addresses to valid output data. The chip enable access time (tCE) is the delay from stable addresses and stable CE to valid data at the output pins. The output enable access time is the delay from the falling edge of OE to valid data at the output pins (assuming the addresses have been stable for at least tACC-tOE time).
Standby Mode
There are two ways to implement the standby mode on the MBM29F016A device, one using both the CE and RESET pins; the other via the RESET pin only. When using both pins, a CMOS standby mode is achieved with CE and RESET inputs both held at VCC 0.3 V. Under this condition the current consumed is less than 5 A. A TTL standby mode is achieved with CE and RESET pins held at VIH. Under this condition the current is reduced to approximately 1 mA. During Embedded Algorithm operation, VCC Active current (ICC2) is required even CE = VIH. The device can be read with standard access time (tCE) from either of these standby modes. When using the RESET pin only, a CMOS standby mode is achieved with RESET input held at VSS 0.3 V (CE = "H" or "L"). Under this condition the current consumed is less than 5 A. A TTL standby mode is achieved with RESET pin held at VIL (CE = "H" or "L"). Under this condition the current required is reduced to approximately 1 mA. Once the RESET pin is taken high, the device requires 500 ns of wake up time before outputs are valid for read access. In the standby mode the outputs are in the high impedance state, independent of the OE input.
Output Disable
With the OE input at a logic high level (VIH), output from the device is disabled. This will cause the output pins to be in a high impedance state.
Autoselect
The autoselect mode allows the reading out of a binary code from the device and will identify its manufacturer and type. This mode is intended for use by programming equipment for the purpose of automatically matching the device to be programmed with its corresponding programming algorithm. This mode is functional over the entire temperature range of the device. To activate this mode, the programming equipment must force VID (11.5 V to 12.5 V) on address pin A9. Two identifier bytes may then be sequenced from the device outputs by toggling address A0 from VIL to VIH. All addresses are don't cares except A0, A1, and A6. (See Table 3.) The manufacturer and device codes may also be read via the command register, for instances when the MBM29F016A is erased or programmed in a system without access to high voltage on the A9 pin. The command sequence is illustrated in Table 6. (Refer to Autoselect Command section.) Byte 0 (A0 = VIL) represents the manufacturer's code (Fujitsu = 04H) and byte 1 (A0 = VIH) represents the device identifier code for MBM29F016A = ADH. These two bytes are given in the table 3. All identifiers for manufactures and device will exhibit odd parity with DQ7 defined as the parity bit. In order to read the proper device codes when executing the Autoselect, A1 must be VIL. (See Table 3.) The Autoselect mode also facilitates the determination of sector group protection in the system. By performing a read operation at the address location XX02H with the higher order address bits A18, A19 and A20 set to the desired sector group address, the device will return 01H for a protected sector group and 00H for a non-protected sector group. 9

Write
Device erasure and programming are accomplished via the command register. The contents of the register serve as inputs to the internal state machine. The state machine outputs dictate the function of the device. The command register itself does not occupy any addressable memory location. The register is a latch used to store the commands, along with the address and data information needed to execute the command. The command register is written by bringing WE to VIL, while CE is at VIL and OE is at VIH. Addresses are latched on the falling edge of WE or CE, whichever happens later; while data is latched on the rising edge of WE or CE, whichever happens first. Standard microprocessor write timings are used. Refer to AC Write Characteristics and the Erase/Programming Waveforms for specific timing parameters.
Sector Group Protection
The MBM29F016A features hardware sector group protection. This feature will disable both program and erase operations in any combination of eight sector groups of memory. Each sector group consists of four adjacent sectors grouped in the following pattern: sectors 0-3, 4-7, 8-11, 12-15, 16-19, 20-23, 24-27, and 28-31 (see Table 5). The sector group protection feature is enabled using programming equipment at the user's site. The device is shipped with all sector groups unprotected. To activate this mode, the programming equipment must force VID on address pin A9 and control pin OE, (suggest VID = 11.5 V), CE = VIL. The sector addresses (A20, A19, and A18) should be set to the sector to be protected. Tables 4 and 5 define the sector address for each of the thirty two (32) individual sectors, and the sector group address for each of the eight (8) individual group sectors. Programming of the protection circuitry begins on the falling edge of the WE pulse and is terminated with the rising edge of the same. Sector addresses must be held constant during the WE pulse. See figures 14 and 21 for sector protection waveforms and algorithm. To verify programming of the protection circuitry, the programming equipment must force VID on address pin A9 with CE and OE at VIL and WE at VIH. Scanning the sector addresses (A20, A19, and A18) while (A6, A1, A0) = (0, 1, 0) will produce a logical "1" code at device output DQ0 for a protected sector. Otherwise the device will produce 00H for unprotected sector. In this mode, the lower order addresses, except for A0, A1, and A6 are DON'T CARES. Address locations with A1 = VIL are reserved for Autoselect manufacturer and device codes. It is also possible to determine if a sector group is protected in the system by writing an Autoselect command. Performing a read operation at the address location XX02H, where the higher order addresses (A20, A19, and A18) are the desired sector group address will produce a logical "1" at DQ0 for a protected sector group. See Table 3 for Autoselect codes. 11
MBM29F016A-70/-90/-12
Temporary Sector Group Unprotection
This feature allows temporary unprotection of previously protected sector groups of the MBM29F016A device in order to change data. The Sector Group Unprotection mode is activated by setting the RESET pin to high voltage (12 V). During this mode, formerly protected sector groups can be programmed or erased by selecting the sector group addresses. Once the 12 V is taken away from the RESET pin, all the previously protected sector groups will be protected again. Refer to Figures 14 and 21. Table 6

Sector Erase Suspend Sector Erase Resume
Erase can be suspended during sector erase with Addr ("H" or "L"), Data (B0H) Erase can be resumed after suspend with Addr ("H" or "L"), Data (30H)
Notes: 1. Address bits A11 to A20 = X = "H" or "L" for all address commands except or Program Address (PA) and Sector Address (SA). 2. Bus operations are defined in Table 2. 3. RA = Address of the memory location to be read. PA = Address of the memory location to be programmed. Addresses are latched on the falling edge of the WE pulse. SA = Address of the sector to be erased. The combination of A20, A19, A18, A17, and A16 will uniquely select any sector. 4. RD = Data read from location RA during read operation. PD = Data to be programmed at location PA. Data is latched on the rising edge of WE. 5. Read and Byte program functions to non-erasing sectors are allowed in the Erase Suspend mode. 6. The system should generate the following address pattens: 555H or 2AAH to addresses A0 to A10. *: Either of the two reset commands will reset the device.
Command Definitions
Device operations are selected by writing specific address and data sequences into the command register. Writing incorrect address and data values or writing them in the improper sequence will reset the device to the read mode. Table 6 defines the valid register command sequences. Note that the Erase Suspend (B0H) and Erase Resume (30H) commands are valid only while the Sector Erase operation is in progress. Moreover, both Read/Reset commands are functionally equivalent, resetting the device to the read mode. 12
MBM29F016A-70/-90/-12
Read/Reset Command
The read or reset operation is initiated by writing the read/reset command sequence into the command register. Microprocessor read cycles retrieve array data from the memory. The device remains enabled for reads until the command register contents are altered. The device will automatically power-up in the read/reset state. In this case, a command sequence is not required to read data. Standard microprocessor read cycles will retrieve array data. This default value ensures that no spurious alteration of the memory content occurs during the power transition. Refer to the AC Read Characteristics and Waveforms for the specific timing parameters.
Autoselect Command
Flash memories are intended for use in applications where the local CPU alters memory contents. As such, manufacture and device codes must be accessible while the device resides in the target system. PROM programmers typically access the signature codes by raising A9 to a high voltage. However, multiplexing high voltage onto the address lines is not generally desirable system design practice. The device contains an autoselect command operation to supplement traditional PROM programming methodology. The operation is initiated by writing the autoselect command sequence into the command register. Following the command write, a read cycle from address XX00H retrieves the manufacture code of 04H. A read cycle from address XX01H returns the device code ADH. (See Table 3). All manufacturer and device codes will exhibit odd parity with the DQ7 defined as the parity bit. Sector state (protection or unprotection) will be informed by address XX02H. Scanning the sector group addresses (A18, A19, A20) while (A6, A1, A0) = (0, 1, 0) will produce a logical "1" at device output DQ0 for a protected sector group. To terminate the operation, it is necessary to write the read/reset command sequence into the register and also to write the Autoselect command during the operation, execute it after writing Read/Reset command sequence.
Byte Programming
The device is programmed on a byte-by-byte basis. Programming is a four bus cycle operation. There are two "unlock" write cycles. These are followed by the program set-up command and data write cycles. Addresses are latched on the falling edge of CE or WE, whichever happens later and the data is latched on the rising edge of CE or WE, whichever happens first. The rising edge of CE or WE (whichever happens first) begins programming. Upon executing the Embedded Program Algorithm command sequence, the system is not required to provide further controls or timings. The device will automatically provide adequate internally generated program pulses and verify the programmed cell margin. This automatic programming operation is completed when the data on DQ7 is equivalent to data written to this bit at which time the device returns to the read mode and addresses are no longer latched. (See Table 7, Hardware Sequence Flags.) Therefore, the device requires that a valid address to the device be supplied by the system at this particular instance of time. Data Polling must be performed at the memory location which is being programmed. Any commands written to the chip during this period will be ignored. If a hardware reset occurs during the programming operation, it is impossible to guarantee the data are being written. Programming is allowed in any sequence and across sector boundaries. Beware that a data "0" cannot be programmed back to a "1". Attempting to do so may either hang up the device or result in an apparent success according to the data polling algorithm but a read from reset/read mode will show that the data is still "0". Only erase operations can convert "0"s to "1"s. Figure 16 illustrates the Embedded ProgrammingTM Algorithm using typical command strings and bus operations. 13
MBM29F016A-70/-90/-12
Chip Erase
Chip erase is a six bus cycle operation. There are two "unlock" write cycles. These are followed by writing the "set-up" command. Two more "unlock" write cycles are then followed by the chip erase command. Chip erase does not require the user to program the device prior to erase. Upon executing the Embedded Erase Algorithm command sequence the device will automatically program and verify the entire memory for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. The automatic erase begins on the rising edge of the last WE pulse in the command sequence and terminates when the data on DQ7 is "1" (see Write Operation Status section) at which time the device returns to read the mode. Figure 17 illustrates the Embedded EraseTM Algorithm using typical command strings and bus operations.
Sector Erase
Sector erase is a six bus cycle operation. There are two "unlock" write cycles. These are followed by writing the "set-up" command. Two more "unlock" write cycles are then followed by the Sector Erase command. The sector address (any address location within the desired sector) is latched on the falling edge of WE, while the command (Data = 30H) is latched on the rising edge of WE. After time-out of 50 s from the rising edge of the last sector erase command, the sector erase operation will begin. Multiple sectors may be erased concurrently by writing the six bus cycle operations on Table 6. This sequence is followed with writes of the Sector Erase command to addresses in other sectors desired to be concurrently erased. The time between writes must be less than 50 s otherwise that command will not be accepted and erasure will start. It is recommended that processor interrupts be disabled during this time to guarantee this condition. The interrupts can be re-enabled after the last Sector Erase command is written. A time-out of 50 s from the rising edge of the last WE will initiate the execution of the Sector Erase command(s). If another falling edge of the WE occurs within the 50 s time-out window the timer is reset. (Monitor DQ3 to determine if the sector erase timer window is still open, see section DQ3, Sector Erase Timer.) Any command other than Sector Erase or Erase Suspend during this time-out period will reset the device to the read mode, ignoring the previous command string. Resetting the device once execution has begun will corrupt the data in that sector. In that case, restart the erase on those sectors and allow them to complete. (Refer to the Write Operation Status section for DQ3, Sector Erase Timer operation.) Loading the sector erase buffer may be done in any sequence and with any number of sectors (0 to 31). Sector erase does not require the user to program the device prior to erase. The device automatically programs all memory locations in the sector(s) to be erased prior to electrical erase. When erasing a sector or sectors the remaining unselected sectors are not affected. The system is not required to provide any controls or timings during these operations. The automatic sector erase begins after the 50 s time out from the rising edge of the WE pulse for the last sector erase command pulse and terminates when the data on DQ7 is "1" (see Write Operation Status section) at which time the device returns to the read mode. Data polling must be performed at an address within any of the sectors being erased. Figure 17 illustrates the Embedded EraseTM Algorithm using typical command strings and bus operations.
Erase Suspend
The Erase Suspend command allows the user to interrupt a Sector Erase operation and then perform data reads from or programs to a sector not being erased. This command is applicable ONLY during a Sector Erase operation which includes the time-out period for sector erase. The Erase Suspend command will be ignored if written during the Chip Erase operation or Embedded Program Algorithm. Writing the Erase Suspend command during 14
MBM29F016A-70/-90/-12
the Sector Erase time-out results in immediate termination of the time-out period and suspension of the erase operation. Any other command written during the Erase Suspend mode will be ignored except the Erase Resume command. Writing the Erase Resume command resumes the erase operation. The addresses are DON'T CARES when writing the Erase Suspend or Erase Resume command. When the Erase Suspend command is written during the Sector Erase operation, the device will take a maximum of 15 s to suspend the erase operation. When the device has entered the erase-suspended mode, the RY/BY output pin and the DQ7 bit will be at logic "1", and DQ6 will stop toggling. The user must use the address of the erasing sector for reading DQ6 and DQ7 to determine if the erase operation has been suspended. Further writes of the Erase Suspend command are ignored. When the erase operation has been suspended, the device defaults to the erase-suspend-read mode. Reading data in this mode is the same as reading from the standard read mode except that the data must be read from sectors that have not been erase-suspended. Successively reading from the erase-suspended sector while the device is in the erase-suspend-read mode will cause DQ2 to toggle. (See the section on DQ2.) After entering the erase-suspend-read mode, the user can program the device by writing the appropriate command sequence for Byte Program. This program mode is known as the erase-suspend-program mode. Again, programming in this mode is the same as programming in the regular Byte Program mode except that the data must be programmed to sectors that are not erase-suspended. Successively reading from the erasesuspended sector while the device is in the erase-suspend-program mode will cause DQ2 to toggle. The end of the erase-suspended program operation is detected by the RY/BY output pin, Data polling of DQ7, or by the Toggle Bit I (DQ6) which is the same as the regular Byte Program operation. Note that DQ7 must be read from the Byte Program address while DQ6 can be read from any address. To resume the operation of Sector Erase, the Resume command (30H) should be written. Any further writes of the Resume command at this point will be ignored. Another Erase Suspend command can be written after the chip has resumed erasing.

Notes: 1. Performing successive read operations from the erase-suspended sector will cause DQ2 to toggle. 2. Performing successive read operations from any address will cause DQ6 to toggle. 3. Reading the byte address being programmed while in the erase-suspend program mode will indicate logic "1" at the DQ2 bit. However, successive reads from the erase-suspended sector will cause DQ2 to toggle.
DQ7
Data Polling The MBM29F016A device features Data Polling as a method to indicate to the host that the embedded algorithms are in progress or completed. During the Embedded Program Algorithm, an attempt to read the device will produce the complement of the data last written to DQ7. Upon completion of the Embedded Program Algorithm, an attempt to read the device will produce the true data last written to DQ7. During the Embedded EraseTM Algorithm, an attempt to read the device will produce a "0" at the DQ7 output. Upon completion of the Embedded Erase Algorithm an attempt to read the device will produce a "1" at the DQ7 output. The flowchart for Data Polling (DQ7) is shown in Figure 18. Data polling will also flag the entry into Erase Suspend. DQ7 will switch "0" to "1" at the start of the Erase Suspend mode. Please note that the address of an erasing sector must be applied in order to observe DQ7 in the Erase Suspend Mode. During Program in Erase Suspend, Data polling will perform the same as in regular program execution outside of the suspend mode. For chip erase, the Data Polling is valid after the rising edge of the sixth WE pulse in the six write pulse sequence. For sector erase, the Data Polling is valid after the last rising edge of the sector erase WE pulse. Data Polling must be performed at sector address within any of the sectors being erased and not a sector that is within a protected sector group. Otherwise, the status may not be valid. Just prior to the completion of Embedded Algorithm operation DQ7 may change asynchronously while the output enable (OE) is asserted low. This means that the device is driving status information on DQ7 at one instant of time and then that byte's valid data at the next instant of time. Depending on when the system samples the DQ7 16
MBM29F016A-70/-90/-12
output, it may read the status or valid data. Even if the device has completed the Embedded Algorithm operations and DQ7 has a valid data, the data outputs on DQ0 to DQ6 may be still invalid. The valid data on DQ0 to DQ7 will be read on the successive read attempts. The Data Polling feature is only active during the Embedded Programming Algorithm, Embedded Erase Algorithm, Erase Suspend, erase-suspend-program mode, or sector erase time-out. (See Table 7.) See Figure 9 for the Data Polling timing specifications and diagrams.
DQ6
Toggle Bit I The MBM29F016A also features the "Toggle Bit I" as a method to indicate to the host system that the embedded algorithms are in progress or completed. During an Embedded Program or Erase Algorithm cycle, successive attempts to read (OE toggling) data from the device at any address will result in DQ6 toggling between one and zero. Once the Embedded Program or Erase Algorithm cycle is completed, DQ6 will stop toggling and valid data will be read on the next successive attempts. During programming, the Toggle Bit I is valid after the rising edge of the fourth WE pulse in the four write pulse sequence. For chip erase, and sector erase the Toggle Bit I is valid after the rising edge of the sixth WE pulse in the six write pulse sequence. For Sector Erase, the Toggle Bit I is valid after the last rising edge of the sector erase WE pulse. The Toggle Bit I is active during the sector erase time out. In programming, if the sector being written to is protected, the Toggle Bit I will toggle for about 2 s and then stop toggling without the data having changed. In erase, the device will erase all the selected sectors except for the ones that are protected. If all selected sectors are protected, the chip will toggle the Toggle Bit I for about 100 s and then drop back into read mode, having changed none of the data. Either CE or OE toggling will cause the DQ6 to toggle. In addition, an Erase Suspend/Resume command will cause DQ6 to toggle. See Figure 10 for the Toggle Bit I timing specifications and diagrams.
DQ5
Exceeded Timing Limits DQ5 will indicate if the program or erase time has exceeded the specified limits (internal pulse count). Under these conditions DQ5 will produce a "1". This is a failure condition which indicates that the program or erase cycle was not successfully completed. Data Polling DQ7, DQ6 is the only operating function of the device under this condition. The CE circuit will partially power down the device under these conditions (to approximately 2 mA). The OE and WE pins will control the output disable functions as described in Table 2. The DQ5 failure condition may also appear if a user tries to program a 1 to a location that is previously programmed to 0. In this case the device locks out and never completes the Embedded Algorithm operation. Hence, the system never reads a valid data on DQ7 bit and DQ6 never stops toggling. Once the device has exceeded timing limits, the DQ5 bit will indicate a "1." Please note that this is not a device failure condition since the device was incorrectly used. If this occurs, reset the device.
DQ3
Sector Erase Timer After the completion of the initial sector erase command sequence the sector erase time-out will begin. DQ3 will remain low until the time-out is complete. Data Polling and Toggle Bit I are valid after the initial sector erase command sequence. If Data Polling or the Toggle Bit I indicates the device has been written with a valid erase command, DQ3 may be used to determine if the sector erase timer window is still open. If DQ3 is high ("1") the internally controlled 17
MBM29F016A-70/-90/-12
erase cycle has begun; attempts to write subsequent commands (other than Erase Suspend) to the device will be ignored until the erase operation is completed as indicated by Data Polling or Toggle Bit I. If DQ3 is low ("0"), the device will accept additional sector erase commands. To insure the command has been accepted, the system software should check the status of DQ3 prior to and following each subsequent sector erase command. If DQ3 were high on the second status check, the command may not have been accepted. Refer to Table 7: Hardware Sequence Flags.
DQ2
Toggle Bit II This toggle bit II, along with DQ6, can be used to determine whether the device is in the Embedded EraseTM Algorithm or in Erase Suspend. Successive reads from the erasing sector will cause DQ2 to toggle during the Embedded EraseTM Algorithm. If the device is in the erase-suspended-read mode, successive reads from the erase-suspended sector will cause DQ2 to toggle. When the device is in the erase-suspended-program mode, successive reads from the byte address of the non-erase suspended sector will indicate a logic "1" at the DQ2 bit. Mode Program Erase Erase Suspend Read (1) (Erase-Suspended Sector) Erase Suspend Program DQ7 DQ7 0 1 DQ7 (2) DQ6 toggles toggles 1 toggles DQ2 1 toggles toggles 1 (2)
Notes: 1. These status flags apply when outputs are read from a sector that has been erase-suspended. 2. These status flags apply when outputs are read from the byte address of the non-erase suspended sector. DQ6 is different from DQ2 in that DQ6 toggles only when the standard program or Erase, or Erase Suspend Program operation is in progress. The behavior of these two status bits, along with that of DQ7, is summarized as follows: For example, DQ2 and DQ6 can be used together to determine the erase-suspend-read mode (DQ2 toggles while DQ6 does not). See also Table 7 and Figure 15. Furthermore, DQ2 can also be used to determine which sector is being erased. When the device is in the erase mode, DQ2 toggles if this bit is read from the erasing sector.
RY/BY
Ready/Busy The MBM29F016A provides a RY/BY open-drain output pin as a way to indicate to the host system that the Embedded Algorithms are either in progress or has been completed. If the output is low, the device is busy with either a program or erase operation. If the output is high, the device is ready to accept any read/write or erase operation. When the RY/BY pin is low, the device will not accept any additional program or erase commands with the exception of the Erase Suspend command. If the MBM29F016A is placed in an Erase Suspend mode, the RY/BY output will be high, by means of connecting with a pull-up resistor to VCC. During programming, the RY/BY pin is driven low after the rising edge of the fourth WE pulse. During an erase operation, the RY/BY pin is driven low after the rising edge of the sixth WE pulse. The RY/BY pin will indicate a busy condition during RESET pulse. Refer to Figure 11 for a detailed timing diagram. The RY/BY pin is pulled high in standby mode. 18
MBM29F016A-70/-90/-12
Since this is an open-drain output, several RY/BY pins can be tied together in parallel with a pull-up resistor to VCC.
RESET
Hardware Reset The MBM29F016A device may be reset by driving the RESET pin to VIL. The RESET pin must be kept low (VIL) for at least 500 ns. Any operation in progress will be terminated and the internal state machine will be reset to the read mode 20 s after the RESET pin is driven low. If a hardware reset occurs during a program operation, the data at that particular location will be indeterminate. When the RESET pin is low and the internal reset is complete, the device goes to standby mode and cannot be accessed. Also, note that all the data output pins are tri-stated for the duration of the RESET pulse. Once the RESET pin is taken high, the device requires tRH of wake up time until outputs are valid for read access. The RESET pin may be tied to the system reset input. Therefore, if a system reset occurs during the Embedded Program or Erase Algorithm, the device will be automatically reset to read mode and this will enable the system's microprocessor to read the boot-up firmware from the Flash memory.
Data Protection
The MBM29F016A is designed to offer protection against accidental erasure or programming caused by spurious system level signals that may exist during power transitions. During power up the device automatically resets the internal state machine in the Read mode. Also, with its control register architecture, alteration of the memory contents only occurs after successful completions of specific multi-bus cycle command sequences. The device also incorporates several features to prevent inadvertent write cycles resulting from VCC power-up and power-down transitions or system noise.
Low VCC Write Inhibit
To avoid initiation of a write cycle during VCC power-up and power-down, a write cycle is locked out for VCC less than 3.2 V (typically 3.7 V). If VCC < VLKO, the command register is disabled and all internal program/erase circuits are disabled. Under this condition the device will reset to the read mode. Subsequent writes will be ignored until the VCC level is greater than VLKO. It is the users responsibility to ensure that the control pins are logically correct to prevent unintentional writes when VCC is above 3.2 V.
Write Pulse "Glitch" Protection
Noise pulses of less than 5 ns (typical) on OE, CE, or WE will not initiate a write cycle.
Logical Inhibit
Writing is inhibited by holding any one of OE = VIL, CE = VIH or WE = VIH. To initiate a write cycle CE and WE must be a logical zero while OE is a logical one.
Power-Up Write Inhibit
Power-up of the device with WE = CE = VIL and OE = VIH will not accept commands on the rising edge of WE. The internal state machine is automatically reset to the read mode on power-up.
