M95020-W 2 Kbit SPI bus EEPROM with high-speed clock

The M95040 is a 4 Kbit (512 x 8) electrically erasable programmable memory (EEPROM), accessed by a high-speed SPI-compatible bus. The other members of the family (M95020 and M95010) are identical, though proportionally smaller (2 and 1 Kbit, respectively).

Each device is accessed by a simple serial interface that is SPI-compatible. The bus signals are C, D and Q.

The device is selected when Chip Select (S) is taken low. Communications with the device can be interrupted using Hold (HOLD). WRITE instructions are disabled by Write Protect (W).
