Description
Introduction
Numonyx(R) OmneoTM Phase Change Memory for embedded applications offers all of the best attributes from other memory types in a new, highly scalable and flexible technology. OmneoTM P5Q PCM is a new type of nonvolatile semiconductor memory that stores information through a reversible structural phase change in a chalcogenide material. The material exhibits a change in material properties, both electrical and optical, when changed from the amorphous (disordered) to the polycrystalline (regularly ordered) state. In the case of Phase Change Memory, information is stored via the change in resistance the chalcogenide material experiences upon undergoing a phase change. The material also changes optical properties after experiencing a phase change, a characteristic that has been successfully mastered for use in current rewritable optical storage devices such as rewritable CDs and DVDs. The OmneoTM P5Q PCM storage element consists of a thin film of chalcogenide contacted by a resistive heating element. In PCM, the phase change is induced in the memory cell by highly localized Joule heating caused by an induced current at the material junction. During a write operation, a small volume of the chalcogenide material is made to change phase. The phase change is a reversible process, and is modulated by the magnitude of injected current, the applied voltage, and the duration of the heating pulse. OmneoTM P5Q PCM combines the benefits of traditional floating gate flash, both NOR-type and NAND-type, with some of the key attributes of RAM and EEpROM. Like NOR flash and RAM technology, PCM offers fast random access times. Like NAND flash, PCM has the ability to write moderately fast. And like RAM and EEpROM, PCM supports bit alterable writes (overwrite). Unlike flash, no separate erase step is required to change information from 0 to 1 and 1 to 0. Unlike RAM, however, the technology is nonvolatile with data retention comparable NOR flash. However, at the current time, PCM technology appears to have a write cycling endurance better than that of NAND or NOR flash, but less than that of RAM. Unlike other proposed alternative memories, OmneoTM P5Q PCM technology uses a conventional CMOS process with the addition of a few additional layers to form the memory storage element. Overall, the basic memory manufacturing process used to make PCM is less complex than that of NAND, NOR or DRAM. Historically, systems have adopted many different types of memory to meet different needs within a design. Some systems might include boot memory, configuration memory, data storage memory, high speed execution memory, and dynamic working memory. The demands of many of today's designs require better performance from the memory subsystem and a reduction in the overall component count. PCM provides many of the attributes of different kinds of memory found in a typical design, enabling the opportunity to consolidate or eliminate of different types of memory.

Product Description
The OmneoTM P5Q PCM s a 128-Mbit (16 Mb x 8) SPI phase change memory, with advanced write protection mechanisms, accessed by a high speed SPI-compatible bus. OmneoTM P5Q PCM product supports four new, high-performance dual and quad input/output instructions: - - - - Dual output fast read (DOFR) instruction used to read data at up to 66 MHz by using both DQ0 and DQ1 pins as outputs Quad output fast read (QOFR) instruction used to read data at up to 50 MHz by using DQ0, DQ1, DQ2(W) and DQ3(HOLD) pins as outputs Dual input fast program (DIFP) instruction used to program data at up to 66 MHz by using both DQ0 and DQ1 pins as inputs Quad input fast program (QIFP) instruction used to program data at up to 50 MHz by using DQ0, DQ1, DQ2(W) and DQ3(HOLD) pins as inputs
These new instructions double or quadruple the transfer bandwidth for read and program operations. The memory can be programmed 1 to 64 bytes at a time, using the page program, dual input fast program and quad input fast program instructions. The memory is organized as 128 sectors that are further divided into 1,024 pages each (131,072 pages in total). For compatibility with flash memory devices, OmneoTM P5Q PCM supports sector erase (128-Kbyte sector) and bulk erase instructions. It can be write protected by software using a mix of volatile and non-volatile protection features, depending on the application needs. The protection granularity is of 128 Kbytes (sector granularity).

SPI modes
These devices can be driven by a microcontroller with its SPI peripheral running in either of the two following modes: - CPOL=0, CPHA=0 - CPOL=1, CPHA=1 For these two modes, input data is latched in on the rising edge of Serial Clock (C), and output data is available from the falling edge of Serial Clock (C). The difference between the two modes, as shown in Figure 4, is the clock polarity when the bus master is in standby mode and not transferring data: - C remains at 0 for (CPOL=0, CPHA=0) - C remains at 1 for (CPOL=1, CPHA=1) Figure 3.

1. The Write Protect (W) and Hold (HOLD) signals should be driven, High or Low as appropriate.
Figure 3 shows an example of three devices connected to an MCU, on an SPI bus. Only one device is selected at a time, so only one device drives the serial data output (DQ1) line at a time, the other devices are high impedance. Resistors R (represented in Figure 3) ensure that the OmneoTM P5Q PCM is not selected if the bus master leaves the S line in the high impedance state. As the bus master may enter a state where all inputs/outputs are in high impedance at the same time (for example, when the bus master is reset), the clock line (C) must be connected to an external pull-down resistor so that, when all inputs/outputs become high impedance, the S line is pulled High while the C line is pulled Low (thus ensuring that S and C do not become High at the same time, and so, that the tSHCH requirement is met). The typical value of R is 100 k, assuming that the time constant R*Cp

(Cp = parasitic capacitance of the bus line) is shorter than the time during which the bus master leaves the SPI bus in high impedance. Example: Cp = 50 pF, that is R*Cp = 5 s <=> the application must ensure that the bus master never leaves the SPI bus in the high impedance state for a time period shorter than 5 s. Figure 4.

Operating features
Definition of `Program', `Bit-alterable Write' and `Program on All 1s': - Program on OmneoTM P5Q PCM devices writes only 0s of the user data to the array and treats 1s as data masks. This is similar to programming on a floating gate flash device. - Bit-alterable Write on OmneoTM P5Q PCM devices involves writing both 0s and 1s of the user data to the array. - Program on all 1s is similar to `program' where only 0s are written to the array and 1s are treated as data masks. Program on all 1s also requires that the entire page being written is previously set to all 1s. Program on all 1s is also referred to as PreSET Write.
4.1
Page programming
To program/write one data byte, two instructions are required: write enable (WREN), which is one byte, and a page program (PP) sequence, which consists of four bytes plus data byte. This is followed by the internal program cycle (of duration tPP). To spread this overhead, the page program (PP) instruction allows up to 64 bytes to be programmed/written at a time, provided that they lie in consecutive addresses on the same page of memory. For optimized timings, it is recommended to use the page program (PP) instruction to program all consecutive targeted bytes in a single sequence versus using several page program (PP) sequences with each containing only a few bytes (see Page program (PP) and Table 15: AC characteristics).
4.2
Dual input fast program
The dual input fast program (DIFP) instruction makes it possible to program/write up to 64 bytes using two input pins at the same time. For optimized timings, it is recommended to use the dual input fast program (DIFP) instruction to program all consecutive targeted bytes in a single sequence rather than using several dual input fast program (DIFP) sequences each containing only a few bytes (see Section 6.11: Dual input fast program (DIFP)).
4.3
Quad input fast program
The quad input fast program (QIFP) instruction makes it possible to program/write up to 64 bytes using four input pins at the same time. For optimized timings, it is recommended to use the quad input fast program (QIFP) instruction to program all consecutive targeted bytes in a single sequence rather than using several quad input fast program (QIFP) sequences each containing only a few bytes (see Section 6.12: Quad input fast program (QIFP)).

4.4
Sector erase and bulk erase
A sector can be erased to all 1s (FFh) at a time using the sector erase (SE) instruction. The entire memory can be erased using the bulk erase (BE) instruction. This starts an internal erase cycle (of duration tSE or tBE). The erase instruction must be preceded by a write enable (WREN) instruction.
4.5
Polling during a write, program or erase cycle
A further improvement in the time to write status register (WRSR), page program (PP), dual input fast program (DIFP), quad input fast program (QIFP), or erase (SE or BE) can be achieved by not waiting for the worst case delay (tW, tPP, tSMEN, tSMEX, tSE, or tBE). The write in progress (WIP) bit is provided in the status register so that the application program can monitor its value, polling it to establish when the previous write cycle, program cycle, or erase cycle is complete.
4.6
Active power and standby power
When Chip Select (S) is Low, the device is selected, and in the active power mode. When Chip Select (S) is High, the device is deselected, but could remain in the active power mode until all internal cycles have completed (program, erase, write status register). The device then goes in to the standby power mode. The device consumption drops to ICC1.
4.7
Status register
The status register contains a number of status and control bits that can be read or set (as appropriate) by specific instructions. See Section 6.4: Read status register (RDSR) for a detailed description of the status register bits.

Protection modes
There are protocol-related and specific hardware and software protection modes. They are described below.
4.8.1
Protocol-related protections
The environments where non-volatile memory devices are used can be very noisy. No SPI device can operate correctly in the presence of excessive noise. To help combat this, the OmneoTM P5Q PCM features the following data protection mechanisms:
n
Power on reset and an internal timer (tPUW) can provide protection against inadvertent changes while the power supply is outside the operating specification Program, erase, and write status register are checked that they consist of a number of clock pulses that is a multiple of eight, before they are accepted for execution All instructions that modify data must be preceded by a write enable (WREN) instruction to set the write enable latch (WEL) bit. This bit is returned to its reset state by the following events: - Power-up - Write disable (WRDI) instruction completion - Write status register (WRSR) instruction completion - Page program (PP) instruction completion - Dual input fast program (DIFP) instruction completion - Quad input fast program (QIFP) instruction completion - Sector erase (SE) instruction completion - Bulk erase (BE) instruction completion The Block Protect bits (see Section 6.4.3: BP3, BP2, BP1, BP0 bits) and top/bottom bit (see Section 6.4.4: Top/bottom bit) allow part of the memory to be configured as readonly. This is the Software Protect Mode (SPM). The Write Protect (W) signal allows the Block Protect (BP3, BP2, BP1, BP0) bits, Top/Bottom (TB) bit and Status Register Write Disable (SRWD) bit to be protected. This is the Hardware Protected Mode (HPM). For more details, see Section 6.5: Write status register (WRSR).

Hold condition
The Hold (HOLD) signal is used to pause any serial communications with the device without resetting the clocking sequence. However, taking this signal Low does not terminate any write status register, program or erase cycle that is currently in progress. To enter the hold condition, the device must be selected, with Chip Select (S) Low. The hold condition starts on the falling edge of the Hold (HOLD) signal, provided that this coincides with Serial Clock (C) being Low (as shown in Figure 5). The hold condition ends on the rising edge of the Hold (HOLD) signal, provided that this coincides with Serial Clock (C) being Low. If the falling edge does not coincide with Serial Clock (C) being Low, the hold condition starts after Serial Clock (C) next goes Low. Similarly, if the rising edge does not coincide with Serial Clock (C) being Low, the hold condition ends after Serial Clock (C) next goes Low (this is shown in Figure 5). During the hold condition, the serial data output (DQ1) is high impedance, and serial data input (DQ0) and Serial Clock (C) are don't care. Normally, the device is kept selected, with Chip Select (S) driven Low, for the whole duration of the hold condition. This is to ensure that the state of the internal logic remains unchanged from the moment of entering the hold condition. If Chip Select (S) goes High while the device is in the Hold condition, this has the effect of resetting the internal logic of the device. To restart communication with the device, it is necessary to drive Hold (HOLD) High, and then to drive Chip Select (S) Low. This prevents the device from going back to the hold condition. Figure 5.

Instructions
All instructions, addresses and data are shifted in and out of the device, most significant bit first. Serial data input DQ0 is sampled on the first rising edge of Serial Clock (C) after Chip Select (S) is driven Low. Then, the one-byte instruction code must be shifted in to the device, most significant bit first, on serial data input DQ0, each bit being latched on the rising edges of Serial Clock (C). The instruction set is listed in Table 4. Every instruction sequence starts with a one-byte instruction code. Depending on the instruction, this might be followed by address bytes, or by data bytes, or by both or none. In the case of a read data bytes (READ), read data bytes at higher speed (FAST_READ), dual output fast read (DOFR), quad output fast read (QOFR), read status register (RDSR) or read identification (RDID) instruction, the shifted-in instruction sequence is followed by a data-out sequence. Chip Select (S) can be driven High after any bit of the data-out sequence is being shifted out. In the case of a page program (PP), dual input fast program (DIFP), quad input fast program (QIFP), sector erase (SE), bulk erase (BE), write status register (WRSR), write enable (WREN), write disable (WRDI), Chip Select (S) must be driven High exactly at a byte boundary, otherwise the instruction is rejected, and is not executed. That is, Chip Select (S) must driven High when the number of clock pulses after Chip Select (S) being driven Low is an exact multiple of eight. All attempts to access the memory array during a write status register cycle, program cycle erase cycle are ignored, and the internal write status register cycle, program cycle, erase cycle continues unaffected.
Note:
Output Hi-Z is defined as the point where data out is no longer driven.

Read identification (RDID)
The read identification (RDID) instruction allows to read the device identification data: - Manufacturer identification (1 byte) - Device identification (2 bytes) The manufacturer identification is assigned by JEDEC, and has the value 20h for Numonyx. Any read identification (RDID) instruction while an erase or program cycle is in progress, is not decoded, and has no effect on the cycle that is in progress. The device is first selected by driving Chip Select (S) Low. Then, the 8-bit instruction code for the instruction is shifted in. After this, the 24-bit device identification stored in the memory will be shifted out on serial data output (DQ1). Each bit is shifted out during the falling edge of Serial Clock (C). The instruction sequence is shown in Figure 8. The read identification (RDID) instruction is terminated by driving Chip Select (S) High at any time during data output. When Chip Select (S) is driven High, the device is put in the standby power mode. Once in the standby power mode, the device waits to be selected, so that it can receive, decode and execute instructions. Table 5. Read identification (RDID) data-out sequence

Read status register (RDSR)
The read status register (RDSR) instruction allows the status register to be read. The status register may be read at any time, even while a program, erase, write status register cycle is in progress. When one of these cycles is in progress, it is recommended to check the write in progress (WIP) bit before sending a new instruction to the device. It is also possible to read the status register continuously, as shown in Figure 9. RDSR is the only instruction accepted by the device while a program, erase, write status register operation is in progress. Table 6.

Status register format
b0 WIP
Status register write protect Top/bottom bit Block protect bits Write enable latch bit Write in progress bit
The status and control bits of the status register are as follows:
6.4.1
WIP bit
The write in progress (WIP) bit indicates whether the memory is busy with a write status register, program, erase cycle. When set to `1', such a cycle is in progress, when reset to `0' no such cycle is in progress. While WIP is `1', RDSR is the only instruction the device will accept; all other instructions are ignored.
6.4.2
WEL bit
The write enable latch (WEL) bit indicates the status of the internal write enable latch. When set to `1' the internal write enable latch is set, when set to `0' the internal write enable latch is reset and no write status register, program, erase instruction is accepted.
6.4.3
BP3, BP2, BP1, BP0 bits
The block protect (BP3, BP2, BP1, BP0) bits are non-volatile. They define the size of the area to be software protected against program (or write) and erase instructions. These bits are written with the write status register (WRSR) instruction. When one or more of the block protect (BP3, BP2, BP1, BP0) bits is set to `1', the relevant memory area (as defined in Table 1) becomes protected against page program (PP), dual input fast program (DIFP),quad input fast program (QIFP), and sector erase (SE) instructions. The block protect (BP3, BP2, BP1, BP0) bits can be written provided that the hardware protected mode has not been set.The bulk erase (BE) instruction is executed if, and only if, all block protect (BP3, BP2, BP1, BP0) bits are 0.

Top/bottom bit
The top/bottom (TB) bit is non-volatile. It can be set and reset with the write status register (WRSR) instruction provided that the write enable (WREN) instruction has been issued. The top/bottom (TB) bit is used in conjunction with the block protect (BP0, BP1, BP2, BP3) bits to determine if the protected area defined by the block protect bits starts from the top or the bottom of the memory array: - When top/bottom bit is reset to `0' (default value), the area protected by the block protect bits starts from the top of the memory array (see Table 1: Protected area sizes) - When top/bottom bit is set to `1', the area protected by the block protect bits starts from the bottom of the memory array (see Table 1: Protected area sizes). The top/bottom bit cannot be written when the SRWD bit is set to `1' and the W pin is driven Low.
6.4.5
SRWD bit
The status register write disable (SRWD) bit is operated in conjunction with the write protect (W) signal. The status register write disable (SRWD) bit and the write protect (W) signal allow the device to be put in the hardware protected mode (when the status register write disable (SRWD) bit is set to `1', and write protect (W) is driven Low). In this mode, the nonvolatile bits of the status register (SRWD, TB, BP3, BP2, BP1, BP0) become read-only bits and the write status register (WRSR) instruction is no longer accepted for execution.

Write status register (WRSR)
The write status register (WRSR) instruction allows new values to be written to the status register. Before it can be accepted, a write enable (WREN) instruction must previously have been executed. After the write enable (WREN) instruction has been decoded and executed, the device sets the write enable latch (WEL). The write status register (WRSR) instruction is entered by driving Chip Select (S) Low, followed by the instruction code and the data byte on serial data input (DQ0). The instruction sequence is shown in Figure 10. The write status register (WRSR) instruction has no effect on b1 and b0 of the status register. Chip Select (S) must be driven High after the eighth bit of the data byte has been latched in. If not, the write status register (WRSR) instruction is not executed. As soon as Chip Select (S) is driven High, the self-timed write status register cycle (whose duration is tW) is initiated. While the write status register cycle is in progress, the status register may still be read to check the value of the write in progress (WIP) bit. The write in progress (WIP) bit is 1 during the self-timed write status register cycle, and is 0 when it is completed. When the cycle is completed, the write enable latch (WEL) is reset. The write status register (WRSR) instruction allows the user to change the values of the block protect (BP3, BP2, BP1, BP0) bits, to define the size of the area that is to be treated as read-only, as defined in Table 1. The write status register (WRSR) instruction also allows the user to set and reset the status register write disable (SRWD) bit in accordance with the Write Protect (W) signal. The status register write disable (SRWD) bit and Write Protect (W) signal allow the device to be put in the hardware protected mode (HPM). The write status register (WRSR) instruction is not executed once the hardware protected mode (HPM) is entered. Read Status Register (RDSR) is the only instruction accepted while WRSR operation is in progress; all other instructions are ignored. Figure 10. Write status register (WRSR) instruction sequence

1. As defined by the values in the block protect (BP3, BP2, BP1, BP0) bits of the status register, as shown in Table 1.
The protection features of the device are summarized in Table 7. When the status register write disable (SRWD) bit of the status register is 0 (its initial delivery state), it is possible to write to the status register provided that the write enable latch (WEL) bit has previously been set by a write enable (WREN) instruction, regardless of the whether Write Protect (W) is driven High or Low. When the status register write disable (SRWD) bit of the status register is set to `1', two cases need to be considered, depending on the state of Write Protect (W): - If Write Protect (W) is driven High, it is possible to write to the status register provided that the write enable latch (WEL) bit has previously been set by a write enable (WREN) instruction. - If write protect (W) is driven Low, it is not possible to write to the status register even if the write enable latch (WEL) bit has previously been set by a write enable (WREN) instruction (attempts to write to the status register are rejected, and are not accepted for execution). As a consequence, all the data bytes in the memory area that are software protected (SPM) by the block protect (BP3, BP2, BP1, BP0) bits of the status register, are also hardware protected against data modification. Regardless of the order of the two events, the hardware protected mode (HPM) can be entered: - by setting the status register write disable (SRWD) bit after driving Write Protect (W) Low - or by driving Write Protect (W) Low after setting the status register write disable (SRWD) bit. The only way to exit the hardware protected mode (HPM) once entered is to pull Write Protect (W) High.

If Write Protect (W) is permanently tied High, the hardware protected mode (HPM) can never be activated, and only the software protected mode (SPM), using the block protect (BP3, BP2, BP1, BP0) bits of the status register, can be used.
6.6
Read data bytes (READ)
The device is first selected by driving Chip Select (S) Low. The instruction code for the read data bytes (READ) instruction is followed by a 3-byte address A[23:0], each bit being latched-in during the rising edge of Serial Clock (C). Then the memory contents, at that address, is shifted out on serial data output (DQ1), each bit being shifted out, at a maximum frequency fR, during the falling edge of Serial Clock (C). The instruction sequence is shown in Figure 11. The first byte addressed can be at any location. The address is automatically incremented to the next higher address after each byte of data is shifted out. The whole memory can, therefore, be read with a single read data bytes (READ) instruction. When the highest address is reached, the address counter rolls over to 000000h, allowing the read sequence to be continued indefinitely. The read data bytes (READ) instruction is terminated by driving Chip Select (S) High. Chip Select (S) can be driven High at any time during data output. Any read data bytes (READ) instruction, while an erase, program, write is in progress, is rejected without having any effects on the cycle that is in progress. Figure 11.

Read data bytes at higher speed (FAST_READ)
The device is first selected by driving Chip Select (S) Low. The instruction code for the read data bytes at higher speed (FAST_READ) instruction is followed by a 3-byte address A[23:0] and a dummy byte, each bit being latched-in during the rising edge of Serial Clock (C). Then the memory contents, at that address, are shifted out on serial data output (DQ1) at a maximum frequency fC, during the falling edge of Serial Clock (C). The instruction sequence is shown in Figure 12. The first byte addressed can be at any location. The address is automatically incremented to the next higher address after each byte of data is shifted out. The whole memory can, therefore, be read with a single read data bytes at higher speed (FAST_READ) instruction. When the highest address is reached, the address counter rolls over to 000000h, allowing the read sequence to be continued indefinitely. The read data bytes at higher speed (FAST_READ) instruction is terminated by driving Chip Select (S) High. Chip Select (S) can be driven High at any time during data output.

Dual output fast read (DOFR)
The dual output fast read (DOFR) instruction is very similar to the read data bytes at higher speed (FAST_READ) instruction, except that the data are shifted out on two pins (pin DQ0 and pin DQ1) instead of only one. Outputting the data on two pins instead of one doubles the data transfer bandwidth compared to the read data bytes at higher speed (FAST_READ) instruction. The device is first selected by driving Chip Select (S) Low. The instruction code for the dual output fast read instruction is followed by a 3-byte address A[23:0] and a dummy byte, each bit being latched-in during the rising edge of Serial Clock (C).

Quad output fast read (QOFR)
The quad output fast read (QOFR) instruction is very similar to the read data bytes at higher speed (FAST_READ) instruction, except that the data are shifted out on four pins (pins DQ0, DQ1, DQ2 and DQ3) instead of only one. Outputting the data on four pins instead of one quadruples the data transfer bandwidth compared to the read data bytes at higher speed (FAST_READ) instruction. The device is first selected by driving Chip Select (S) Low. The instruction code for the quad output fast read instruction is followed by a 3-byte address A[23:0] and a dummy byte, each bit being latched-in during the rising edge of Serial Clock (C). Then the memory contents, at that address, are shifted out on DQ0, DQ1, DQ2 and DQ3 at a maximum frequency fC, during the falling edge of Serial Clock (C).

Page program (PP)
This definition applies to all flavors of Page Program: Legacy Program, Bit-alterable Write and Program on all 1s. The page program (PP) instruction allows bytes to be programmed/written in the memory. Before it can be accepted, a write enable (WREN) instruction must previously have been executed. After the write enable (WREN) instruction has been decoded, the device sets the write enable latch (WEL). The page program (PP) instruction is entered by driving Chip Select (S) Low, followed by the instruction code, three address bytes and at least one data byte on serial data input (DQ0). If the 6 least significant address bits (A5-A0) are not all zero, all transmitted data that goes beyond the end of the current page are programmed from the start address of the same page (from the address whose 6 least significant bits (A5-A0) are all zero). Chip Select (S) must be driven Low for the entire duration of the sequence. The instruction sequence is shown in Figure 15. If more than 64 bytes are sent to the device, previously latched data are discarded and the last 64 data bytes are guaranteed to be programmed/written correctly within the same page. If less than 64 data bytes are sent to device, they are correctly programmed/written at the requested addresses without having any effects on the other bytes of the same page. (With Program on all 1s, the entire page should already have been set to all 1s (FFh).) For optimized timings, it is recommended to use the page program (PP) instruction to program all consecutive targeted bytes in a single sequence versus using several page program (PP) sequences with each containing only a few bytes (see Table 15: AC characteristics). Chip Select (S) must be driven High after the eighth bit of the last data byte has been latched in, otherwise the page program (PP) instruction is not executed. As soon as Chip Select (S) is driven High, the self-timed page program cycle (whose duration is tPP) is initiated. While the page program cycle is in progress, the status register may be read to check the value of the write in progress (WIP) bit. The write in progress (WIP) bit is 1 during the self-timed page program cycle, and is 0 when it is completed. At some unspecified time before the cycle is completed, the write enable latch (WEL) bit is reset. RDSR is the only instruction accepted while a Page Program operation is in progress; all other instructions are ignored. A page program (PP) instruction applied to a page which is protected by the block protect (BP3, BP2, BP1, BP0) bits (see Table 1 and Table 2) is not executed.

The sector erase (SE) instruction sets to `1' (FFh) all bits inside the chosen sector. Before it can be accepted, a write enable (WREN) instruction must previously have been executed. After the write enable (WREN) instruction has been decoded, the device sets the write enable latch (WEL). The sector erase (SE) instruction is entered by driving Chip Select (S) Low, followed by the instruction code, and three address bytes on serial data input (DQ0). Any address inside the sector (see Table 2) is a valid address for the sector erase (SE) instruction. Chip Select (S) must be driven Low for the entire duration of the sequence. The instruction sequence is shown in Figure 18. Chip Select (S) must be driven High after the eighth bit of the last address byte has been latched in, otherwise the sector erase (SE) instruction is not executed. As soon as Chip Select (S) is driven High, the self-timed sector erase cycle (whose duration is tSE) is initiated.

Chip Select (S) must be driven High after the eighth bit of the instruction code has been latched in, otherwise the bulk erase instruction is not executed. As soon as Chip Select (S) is driven High, the self-timed bulk erase cycle (whose duration is tBE) is initiated. While the bulk erase cycle is in progress, the status register may be read to check the value of the write in progress (WIP) bit. The write in progress (WIP) bit is 1 during the self-timed bulk erase cycle, and is 0 when it is completed. At some unspecified time before the cycle is completed, the write enable latch (WEL) bit is reset. RDSR is the only instruction accepted while device is busy with erase operation; all other instructions are ignored. The bulk erase (BE) instruction is executed only if all block protect (BP3, BP2, BP1, BP0) bits are 0. The bulk erase (BE) instruction is ignored if one, or more, sectors are protected. Figure 19.

Power-up and power-down

Power-up and power-down
At power-up and power-down, the device must not be selected (that is Chip Select (S) must follow the voltage applied on VCC until VCC reaches the correct value: - VCC(min) at power-up, and then for a further delay of tVSL - VSS at power-down. A safe configuration is provided in Section 3: SPI modes. To avoid data corruption and inadvertent write operations during power-up, a power on reset (POR) circuit is included. The logic inside the device is held reset while VCC is less than the power on reset (POR) threshold voltage, VWI - all operations are disabled, and the device does not respond to any instruction. Moreover, the device ignores all write enable (WREN), page program (PP), dual input fast program (DIFP), sector erase (SE), bulk erase (BE), write status register (WRSR) instructions until a time delay of tPUW has elapsed after the moment that VCC rises above the VWI threshold. However, the correct operation of the device is not guaranteed if, by this time, VCC is still below VCC(min). No write status register, program, erase instructions should be sent until the later of: - tPUW after VCC has passed the VWI threshold - tVSL after VCC has passed the VCC(min) level. These values are specified in Table 8. If the time, tVSL, has elapsed, after VCC rises above VCC(min), the device can be selected for read instructions even if the tPUW delay has not yet fully elapsed. After power-up, the device is in the following state: - The device is in the standby power mode - The write enable latch (WEL) bit is reset - The write in progress (WIP) bit is reset Normal precautions must be taken for supply line decoupling, to stabilize the VCC supply. Each device in a system should have the VCC line decoupled by a suitable capacitor close to the package pins (generally, this capacitor is of the order of 100 nF). At power-down, when VCC drops from the operating voltage, to below the power on reset (POR) threshold voltage, VWI, all operations are disabled and the device does not respond to any instruction (the designer needs to be aware that if power-down occurs while a write, program or erase cycle is in progress, some data corruption may result).
