The memory is organized as 32 sectors, each containing pages. Each page is bytes wide. Thus, the whole memory can be viewed as consisting daatasheet 81 92 pages, or 2 bytes. The whole memory can be erased using the Bulk Erase instruction, or a sector at a time, using the Sector Erase instruction.

Values are latched on the rising edge of Serial Clock M25p116. Unless an internal Program, Erase or Write Status Register cycle is in dataseet, the device will be in the Standby mode this is not the Deep Power-down m255p16. After Power-up, a falling edge on Chip Select S is required prior to the start of any instruction. The difference between the two modes, as shown in Figure 5, is the clock polarity when the bus master is in Stand-by mode and not transferring data: Only one device is selected at a time, so only m255p16 device drives the Serial Data Output Q line at a time, the other devices are high impedance.
Resistors R represented in Figure 4 ensure that the M25P16 is not selected if the Bus Master leaves the S line in the high impedance state. This is followed by the internal Program cycle of duration t PP. To spread this overhead, the Page Program PP instruction allows up to bytes to be programmed at a time changing bits from 1 to 0provided that they lie in consecutive addresses on the same page of memory.
AC characteristics Grade 6. Before this can be applied, the bytes of memory need to have been erased to all 1s FFh. This can be achieved either a sector at a time, using the Sector Erase SE instruction, or throughout the entire memory, j25p16 the Bulk Erase BE instruction. This starts an internal Erase cycle of duration tgE or t BE.
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. The device then goes in to the Stand-by Power mode. The device consumption drops to I CC1. This can be used as an extra software protection mechanism, when the device is not in active use, to protect m25o16 device from inadvertent Write, Program or Erase instructions.
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 M25P1 6 features the following data protection mechanisms: This bit is returned to its reset state by the following events: However, taking this signal Low does not terminate any Write Status Register, Program or Erase cycle that is currently in progress. This is shown in Figure 6.
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.
This prevents the device from going back to the Hold condition. Each page can be individually programmed bits are programmed from 1 to m255p16. Then, the one-byte instruction code must be shifted in to the device, most significant bit first, on Serial Data Input Deach bit being latched on the m25p6 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.
Chip Select S can be driven High after any bit of the data-out sequence is being shifted out. That xatasheet, Chip Select S must driven High when the number of clock pulses after Chip Select S being driven Low is an exact multiple of All attempts to access the memory array during a Write Status Register cycle, Program cycle or Erase cycle are ignored, and the internal Write Status Register cycle, Program cycle or Erase cycle continues unaffected.
The device identification is assigned by the device manufacturer, and indicates the memory type in the first byte 20hand the memory capacity of the device in the second byte 15h. 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.
This is followed by the bit device identification, stored in the memory, being shifted out on Datwsheet Data Output Qeach bit being shifted out during the falling edge of Serial Clock C. The instruction sequence is shown in Figure Once in the Stand-by Power mode, the device waits to be selected, so that it can receive, decode and execute instructions. Read Identification RDID instruction sequence and data-out sequence 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 28 29 30 31 anmuWuuuuuuuuuui.
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 dqtasheet Figure 1 1. When set to datsheetsuch a cycle is in progress, when reset to 0 no such cycle is in progress.
They define the size of the area to be software protected against Program and Erase instructions. Chip Select 2m5p16 must be driven High after the eighth bit of the data byte has been latched in. Attempts to write to the Status Register are rejected, and are not accepted for execution. Then the memory contents, at that address, is shifted out on Serial Data Output Fatasheeteach bit being shifted out, at a maximum frequency f Rduring the falling edge of Serial Clock C. 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. When the highest address is reached, the address counter rolls over to OOOOOOh, allowing the read sequence to be continued indefinitely.
Chip Select S can be driven High at any time during data output. Address bits A23 to A21 are Don’t Care. Then the memory contents, at that address, is shifted out on Serial Data Output Qeach bit being shifted out, at a maximum frequency f cduring the falling edge of Serial Clock C. If the 8 least significant address bits A7-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 8 least significant bits A7-A0 are all zero.
Chip Select S must be driven Low for the entire duration of the sequence. If more than bytes are sent to the device, previously latched data are discarded and the last data bytes are guaranteed to be programmed correctly within the same page.
