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. Maximum frequency (READ DATA BYTES at HIGHER SPEED operation) in the standard VCC range 2.7V to 3.6V equals 75MHz

  2. Maximum frequency (READ DATA BYTES at HIGHER SPEED operation) in the extended VCC range 2.3V to 2.7V equals 40MHz

  3. UID/CFD protection feature
