Signal description M45PE80

2 Signal description

2.1 Serial Data Output (Q)

This output signal is used to transfer data serially out of the device. Data is shifted out on the falling edge of Serial Clock (C).

2.2 Serial Data Input (D)

This input signal is used to transfer data serially into the device. It receives instructions, addresses, and the data to be programmed. Values are latched on the rising edge of Serial Clock (C).

2.3 Serial Clock (C)

This input signal provides the timing of the serial interface. Instructions, addresses, or data present at Serial Data Input (D) are latched on the rising edge of Serial Clock (C). Data on Serial Data Output (Q) changes after the falling edge of Serial Clock (C).

2.4 Chip Select (S )

When this input signal is High, the device is deselected and Serial Data Output (Q) is at high impedance. Unless an internal Read, Program, Erase or Write cycle is in progress, the device will be in the Standby mode (this is not the Deep Power-down mode). Driving Chip Select (S) Low enables the device, placing it in the active power mode. After Power-up, a falling edge on Chip Select (S) is required prior to the start of any instruction.

2.5 Reset (Reset )

The Reset (Reset) input provides a hardware reset for the memory. When Reset (Reset) is driven High, the memory is in the normal operating mode. When Reset (Reset) is driven Low, the device enters the Reset mode. In this mode, the output Q is high impedance: If an internal operation (Write, Erase or Program cycle) is in progress when Reset (Reset) is driven Low, the device enters the Reset mode and any on-going Write, Program or Erase cycle is aborted. The addressed data may be lost.

2.6 Write Protect (W )

This input signal puts the device in the Hardware Protected mode, when Write Protect (W) is connected to VSS, causing the first 256 pages of memory to become read-only by protecting them from write, program and erase operations. When Write Protect (W) is connected to VCC, the first 256 pages of memory behave like the other pages of memory.

M45PE80 Signal description

2.7 V CC supply voltage

VCC is the supply voltage.

2.8 V SS ground

VSS is the reference for the VCC supply voltage.

3 SPI 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 Stand-by mode and not transferring data:
  • C remains at 0 for (CPOL=0, CPHA=0)
  • C remains at 1 for (CPOL=1, CPHA=1)

Operating features M45PE80

4 Operating features

4.1 Sharing the overhead of modifying data

To write or program one (or more) data bytes, two instructions are required: Write Enable (WREN), which is one byte, and a Page Write (PW) or Page Program (PP) sequence, which consists of four bytes plus data. This is followed by the internal cycle (of duration t PW or tPP). To share this overhead, the Page Write (PW) or Page Program (PP) instruction allows up to 256 bytes to be programmed (changing bits from 1 to 0) or written (changing bits to 0 or 1) at a time, provided that they lie in consecutive addresses on the same page of memory.

4.2 An easy way to modify data

The Page Write (PW) instruction provides a convenient way of modifying data (up to 256 contiguous bytes at a time), and simply requires the start address, and the new data in the instruction sequence. The Page Write (PW) instruction is entered by driving Chip Select (S ) Low, and then transmitting the instruction byte, three address bytes (A23-A0) and at least one data byte, and then driving Chip Select (S ) High. While Chip Select (S) is being held Low, the data bytes are written to the data buffer, starting at the address given in the third address byte (A7-A0). When Chip Select (S ) is driven High, the Write cycle starts. The remaining, unchanged, bytes of the data buffer are automatically loaded with the values of the corresponding bytes of the addressed memory page. The addressed memory page then automatically put into an Erase cycle. Finally, the addressed memory page is programmed with the contents of the data buffer. All of this buffer management is handled internally, and is transparent to the user. The user is given the facility of being able to alter the contents of the memory on a byte-by-byte basis. For optimized timings, it is recommended to use the Page Write (PW) instruction to write all consecutive targeted bytes in a single sequence versus using several Page Write (PW) sequences with each containing only a few bytes (see Page Write (PW) and Table 14: AC characteristics (50 MHz operation)).

M45PE80 Operating features

4.3 A fast way to modify data

The Page Program (PP) instruction provides a fast way of modifying data (up to 256 contiguous bytes at a time), provided that it only involves resetting bits to 0 that had previously been set to 1. This might be:

  • when the designer is programming the device for the first time
  • when the designer knows that the page has already been erased by an earlier Page Erase (PE) or Sector Erase (SE) instruction. This is useful, for example, when storing a fast stream of data, having first performed the erase cycle when time was available
  • when the designer knows that the only changes involve resetting bits to 0 that are still set to 1. When this method is possible, it has the additional advantage of minimizing the number of unnecessary erase operations, and the extra stress incurred by each page. 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 14: AC characteristics (50 MHz operation)).

4.4 Polling during a Write, Program or Erase cycle

A further improvement in the write, program or erase time can be achieved by not waiting for the worst case delay (tPW, tPP, tPE, or tSE). 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 cycle is complete.

4.5 Reset

An internal Power-On Reset circuit helps protect against inadvertent data writes. Addition protection is provided by driving Reset (Reset ) Low during the Power-on process, and only driving it High when VCC has reached the correct voltage level, VCC(min).

4.6 Active Power, Stand-by Powe r and Deep Power-Down modes

When Chip Select (S) is Low, the device is enabled, and in the Active Power mode. When Chip Select (S) is High, the device is disabled, but could remain in the Active Power mode until all internal cycles have completed (Program, Erase, Write). The device then goes in to the Stand-by Power mode. The device consumption drops to I CC1. The Deep Power-down mode is entered when the specific instruction (the Enter Deep Power-down Mode (DP) instruction) is executed. The device consumption drops further to I CC2. The device remains in this mode until another specific instruction (the Release from Deep Power-down Mode) is executed. While in the Deep Power-down mode, the device ignores all Write, Program and Erase instructions (see Deep Power-down (DP)). This can be used as an extra software protection mechanism, when the device is not in active use, to protect the device from inadvertent Write, Program or Erase instructions.

Operating features M45PE80

4.7 Status Register

The Status Register contains two status bits that can be read by the Read Status Register (RDSR) instruction. See Section 6.4: Read Status Register (RDSR) for a detailed description of the Status Register bits.

4.8 Protection modes

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 M45PE80 boasts the following data protection mechanisms:

  • 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 instructions 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: –P o w e r - u p – Reset (RESET ) driven Low – Write Disable (WRDI) instruction completion – Page Write (PW) instruction completion – Page Program (PP) instruction completion – Page Erase (PE) instruction completion – Sector Erase (SE) instruction completion
  • The Hardware Protected mode is entered when Write Protect (W) is driven Low, causing the first 256 pages of memory to become read-only. When Write Protect (W) is driven High, the first 256 pages of memory behave like the other pages of memory
  • The Reset (Reset) signal can be driven Low to protect the contents of the memory during any critical time, not just during Power-up and Power-down.
  • In addition to the low power consumption feature, the Deep Power-down mode offers extra software protection from inadvertent Write, Program and Erase instructions while the device is not in active use.

6.7 Page Write (PW)

The Page Write (PW) instruction allows bytes to be 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 Write (PW) 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 (D). The rest of the page remains unchanged if no power failure occurs and the device is not reset during the write cycle. The Page Write (PW) instruction performs a page erase cycle even if only one byte is updated. If the 8 least significant address bits (A7-A0) are not all zero, all transmitted data exceeding the addressed page boundary roll over, and are written from the start address of the same page (the one whose 8 least significant address bits (A7-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 12. If more than 256 bytes are sent to the device, previously latched data are discarded and the last 256 data bytes are guaranteed to be written correctly within the same page. If less than

256 Data bytes are sent to device, they are correctly written at the requested addresses

without having any effects on the other bytes of the same page. For optimized timings, it is recommended to use the Page Write (PW) instruction to write all consecutive targeted bytes in a single sequence versus using several Page Write (PW) sequences with each containing only a few bytes (see Table 14: AC characteristics (50 MHz operation)). Chip Select (S ) must be driven High after the eighth bit of the last data byte has been latched in, otherwise the Page Write (PW) instruction is not executed. As soon as Chip Select (S) is driven High, the self-timed Page Write cycle (whose duration is tPW) is initiated. While the Page Write 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 Write cycle, and is 0 when it is completed. At some unspecified time before the cycle is complete, the Write Enable Latch (WEL) bit is reset. A Page Write (PW) instruction applied to a page that is Hardware Protected is not executed. Any Page Write (PW) instruction, while an Erase, Program or Write cycle is in progress, is rejected without having any effects on the cycle that is in progress.

6.8 Page Program (PP)

The Page Program (PP) instruction allows bytes to be programmed in the memory (changing bits from 1 to 0, only). 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 (D). If the 8 least significant address bits (A7-A0) are not all zero, all transmitted data exceeding the addressed page boundary roll over, and are programmed from the start address of the same page (the one whose 8 least significant address bits (A7-A0) are all zero). Chip Select ) must be driven Low for the entire duration of the sequence. The instruction sequence is shown in Figure 13. If more than 256 bytes are sent to the device, previously latched data are discarded and the last 256 data bytes are guaranteed to be programmed correctly within the same page. If less than 256 Data bytes are sent to device, they are correctly programmed at the requested addresses without having any effects on the other bytes of the same page. 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 14: AC characteristics (50 MHz operation)). 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 complete, the Write Enable Latch (WEL) bit is reset. A Page Program (PP) instruction applied to a page that is Hardware Protected is not executed. Any Page Program (PP) instruction, while an Erase, Program or Write cycle is in progress, is rejected without having any effects on the cycle that is in progress.

M45PE80 Power-up and Power-down

7 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 POR threshold value, VWI – all operations are disabled, and the device does not respond to any instruction. Moreover, the device ignores all Write Enable (WREN), Page Write (PW), Page Program (PP), Page Erase (PE) and Sector Erase (SE) 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, Program or Erase instructions should be sent until the later of:
  • tPUW after VCC passed the VWI threshold
  • tVSL after VCC passed the VCC(min) level These values are specified in Table 6. If the delay, tVSL, has elapsed, after VCC has risen above VCC(min), the device can be selected for READ instructions even if the tPUW delay is not yet fully elapsed. As an extra protection, the Reset (Reset) signal could be driven Low for the whole duration of the Power-up and Power-down phases. At Power-up, the device is in the following state:
  • The device is in the Standby mode (not the Deep Power-down mode).
  • The Write Enable Latch (WEL) bit is reset.
  • The Write In Progress (WIP) bit is reset. Normal precautions must be taken for supply rail decoupling, to stabilize the VCC feed. Each device in a system should have the VCC rail 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 POR threshold value, VWI, all operations are disabled and the device does not respond to any instruction. (The designer needs to be aware that if a Power-down occurs while a Write, Program or Erase cycle is in progress, some data corruption can result.)
