w39l040 publication release date: february 10, 2003 - 3 - revision a3 6. functional description device bus operation read mode the read operation of the w39l040 is controlled by #ce and #oe, both of which have to be low for the host to obtain data from the outputs. #ce is used for device selection. when #ce is high, the chip is de-selected and only standby power will be consum ed. #oe is the output control and is used to gate data from the output pins. the data bus is in high impedance state when either #ce or #oe is high. refer to the timing waveforms for further details. write mode device erasure and programming are accomplished vi a the command register. the contents of the register serve as inputs to the in ternal 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 t he address and data information needed to execute the command. the command register is written by bringing #we to logic low state, while #ce is at logic low state and #oe is at logic hi gh state. 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 er ase/programming waveforms for specific timing parameters. standby mode there are two ways to implement the standby m ode on the w39l040 device, both using the #ce pin. a cmos standby mode is achieved with the #ce input held at v dd 0.3v. under this condition the current is typically reduced to less than 15 a (max). a ttl standby mode is achieved with the #ce pin held at v ih . under this condition the current is typically reduced to 2 ma(max). in the standby mode the outputs are in the hi gh impedance state, independent of the #oe input. output disable mode with the #oe input at a logic high level (v ih ), output from the device is disabled. this will cause the output pins to be in a high impedance state. auto-select mode the auto-select mode allows the reading 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 progra mmed with its corresponding programming algorithm. this mode is functional over the ent ire temperature range of the device. to activate this mode, the programming equipment must force v id (11.5v to 12.5v) on address pin a9. two identifier bytes may then be sequenced from the device outputs by t oggling address a0 from v il to v ih . all addresses are don t cares except a0 and a1 (see "auto-select codes").
w39l040 - 4 - the manufacturer and device codes may also be r ead via the command register, for instance, when the w39l040 is erased or programmed in a system without access to high voltage on the a9 pin. the command sequence is illustrated in "auto-select codes". byte 0 (a0 = v il ) represents the manufacturer s code (winbond = dah) and byte 1 (a0 = v ih ) the device identifier code (w39l040 = b6hex ). all identifiers for manufac turer and device will exhibit odd parity with dq7 defined as the parity bit. in order to read the proper device codes when executing the auto-select, a1 must be low state. data protection the w39l040 is designed to offer protection against acci dental erasure or programming caused by spurious system level signals that may exist dur ing 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 onl y occurs after successful completion of specific multi-bus cycle command sequences. the device also incorporates several features to prevent inadvertent write cycles resulting from v dd power-up and power-down transitions or system noise. boot block operation there are four alternatives to set the boot blo ck. either 16k-byte or 64k -byte in the top/bottom location of this device can be locked as boot blo ck, which can be used to store boot codes. it is located in the last 16k/64k byte s or first 16k/64k bytes of the memory with the address range from 7c000/ 70000(hex) to 7ffff(hex) for top locati on or 00000(hex) to 03fff/0ffff(hex) for bottom location. see command codes for boot block lockout enable for t he specific code. once this feature is set the data for the designated block cannot be erased or pr ogrammed (programming lockout), other memory locations can be changed by the regular programming method. in order to detect whether the boot block feature is set on the first/last 16k/64k-bytes block or not, users can perform software command sequence: enter the product identification mode (see command codes for identification/ boot block lockout detection for specific code), and then read from address 0002(hex) for first (bottom) location or 7fff2(hex) for last (top) location. if the dq0/dq1 of output data is "0/1," the 16k-b ytes boot block programming lockout feature will be activated; if the dq0/dq1 of output data is "1/1," the 64k-bytes boot block programming lockout feature will be activated. if the dq0/dq1 of output data is "0/0," for both 16k/64k-bytes boot block, the lockout feature will be inactivated and the block can be erased/programmed. to return to normal operation, perform a three- byte command sequence (or an alternate single-byte command) to exit the identification mode. fo r the specific code, see command codes for identification/boot blo ck lockout detection. low v dd inhibit to avoid initiation of a write cycle during v dd power-up and power-down, the w39l040 locks out when v dd < 2.0v (see dc characteristics section fo r voltages). the write and read operations are inhibited when v dd is less than 2.0v typical. the w39l040 ignores all write and read operations until v dd > 2,0v. the user must ensure that the control pins are in the correct logic state when v dd > 2.0v to prevent unintentional writes. write pulse "glitch" protection noise pulses of less than 10 ns (typical) on #oe, #ce, or #we will not initiate a write cycle.
w39l040 publication release date: february 10, 2003 - 5 - revision a3 logical inhibit writing is inhibited by holding any one of #oe = v il , #ce = v ih , or #we = v ih . to initiate a write cycle #ce and #we must be a logical zero while #oe is a logical one. power-up write and read inhibit power-up of the device with #we = #ce = v il and #oe = v ih will not accept commands on the rising edge of #we except 5ms delay (see the power up timi ng in ac characteristics). the internal state machine is automatically reset to the read mode on power-up. command definitions device operations are selected by writing s pecific 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. "command definitions " defines the valid register command sequences. read command the device will automatically power-up in the read state. in this case, a command sequence is not required to read data. standard microprocessor read cycl es will retrieve array data. this default value ensures that no spurious alteration of the memory content occurs during the power transition. the device will automatically returns to r ead state after completing an embedded program or embedded erase algorithm. refer to the ac read characteristics and wave forms for the specific timing parameters. auto-select command flash memories are intended for use in applications where the local cpu can alter memory contents. as such, manufacture and device codes must be acce ssible while the device resides in the target system. prom programmers typically access the si gnature codes by raising a9 to a high voltage. however, multiplexing high voltage onto the address lines is not generally a desirable system design practice. the device contains an auto-select command operat ion to supplement traditional prom programming methodology. the operation is initiated by writ ing the auto-select command sequence into the command register. following the command write, a read cycle from address xx00h retrieves the manufacture code of dah. a read cycle from address xx01h returns the device code (w39l040 = b6hex). to terminate the operation, it is necessary to write the auto-select exit command sequence into the register. byte program command the device is programmed on a byte-by-byte basis. programming is a four-bus-cycle operation. the program command sequence is initiated by writing two "unlock" write cycles, followed by the program set-up command. the program address and data are wr itten next, which in turn initiate the embedded program algorithm. addresses are latched on t he 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 using the embedded program
w39l040 - 6 - algorithm. upon executing the algorit hm, the system is not required to provide further controls or timings. the device will automatically provide adequat e internally generated program pulses and verify the programmed cell margin. the automatic programming operation is comple ted when the data on dq7 (also used as data polling) is equivalent to the data written to this bi t at which time the device returns to the read mode and addresses are no longer latched (see "hardwar e sequence flags"). therefore, the device requires that a valid address to the device be supplied by the system at this particular instance of time for data polling operations. data polling must be performed at the memory location which is being programmed. any commands written to the chip during t he embedded program algorithm will be ignored. if a hardware reset occurs during the programming operati on, the data at that particular location will be corrupted. programming is allowed in any sequence and across sector boundaries. beware that a data "0" cannot be programmed back to a "1". attempting to program 0 back to 1, the toggle bit will stop toggling. only erase operations can convert "0"s to "1"s. refer to the programming command flow chart us ing typical command strings and bus operations. chip erase command chip erase is a six-bus-cycle operation. there are two "unlock" write cycles , followed by writing the "set-up" command. two more "unl ock" write cycles are asserted, 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 devic e will automatically erase and verify the entire memory for an all one data pattern. the eras e is performed sequentially on each sectors at the same time (see "feature"). the syst em 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" at whic h time the device returns to read the mode. refer to the erase command flow chart usi ng typical command strings and bus operations. sector/page erase command sector/page erase is a six bus cycles operation. t here are two "unlock" write cycles, followed by writing the "set-up" command. two more "unlock" write cycles t hen follows by the sector erase command. the sector/page address (any address loca tion within the desired sector/page) is latched on the falling edge of #we, while the command (30h /50h) is latched on the rising edge of #we. sector/page erase does not require the user to pr ogram the device prior to erase. when erasing a sector/page or sectors/pages the remaining unselect ed sectors/pages are not a ffected. the system is not required to provide any controls or timings during these operations. the automatic sector/page erase begins after the er ase command is completed, right from the rising edge of the #we pulse for the last sector/page erase command pulse and terminates when the data on dq7, data polling, is "1" at which time the dev ice returns to the read mode. data polling must be performed at an address within any of the sectors/pages being erased. refer to the erase command flow chart usi ng typical command strings and bus operations.
w39l040 publication release date: february 10, 2003 - 7 - revision a3 write operation status dq7: data polling the w39l040 device features data polling as a me thod 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 completi on of the embedded program algorithm, an attempt to read the device will produce the true data last written to dq7. during the embedded erase algorithm, an attempt to read the device will produce a "0" at the dq7 output. upon completion of the embedded erase algorit hm, an attempt to read the device will produce a "1" at the dq7 output. for chip erase, the data polling is valid after t he rising edge of the sixth pulse in the six #we write pulse sequences. 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 addresses within any of the sectors being erased. otherwise, the status may not be valid. just prior to the completion of embedded algor ithm operations dq7 may change asynchronously while the output enable (#oe) is asserted low. this m eans that the device is dr iving 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 output, it may read the status or valid data. even if the device has completed the embedded algorithm operations and dq 7 has a valid data, the data outputs on dq0 ? dq6 may be still invalid. the valid data on dq0 ? dq7 will be read on the successive read attempts. the data polling feature is only active during the embedded programming algorithm, embedded erase algorithm, or sector erase ti me-out (see "command definitions"). dq6: toggle bit the w39l040 also features the "toggle bit" as a me thod 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 comp leted, dq6 will stop toggling and valid data will be read on the next successive attempt. during programming, the toggle bit is valid after the rising edge of the fourth #we pulse in the four write pulse sequence. for chip erase, the toggle bit is valid after the rising edge of the sixth #we pulse in the six write pulse sequence. for sector/page erase, the toggle bit is valid after the last rising edge of the sector/page erase #we pulse. the toggle bit is active during the sector/page erase time-out. either #ce or #oe toggling will cause dq6 to toggle.
