Description :

The device feature a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO).

Serial access to the device is enabled by CS# input. When it is in Dual Output read mode, the SI and SO pins become SIO0 and SIO1 pins for data output. The device provides sequential read operation on whole chip. After program/erase command is issued, auto program/erase algorithms which program/erase and verify the specified page or sector/block locations will be executed. Program command is executed on byte basis, or page basis, or word basis for erase command is executes on sector, or block, or whole chip basis.

M25P40 datasheet


Description :

The M25P40 is an 4Mb (512Kb x 8) serial Flash memory device with advanced writeprotection mechanisms accessed by a high-speed SPI-compatible bus. The device supports high-performance commands for clock frequency up to 75MHz. The memory can be programmed 1 to 256 bytes at a time using the PAGE PROGRAM command. It is organized as 8 sectors, each containing 256 pages. Each page is 256 bytes wide. The entire memory can be erased using the BULK ERASE command, or it can be erased one sector at a time using the SECTOR ERASE command.


1. SPI bus-compatible serial interface
2. 4Mb Flash memory
3. 75 MHz clock frequency (maximum)
4. 2.3V to 3.6V single supply voltage
5. Page program (up to 256 bytes) in 0.8ms (TYP)
