• Manufacturer Part Number: M95010-BN3
• Description: 4Kbit, 2Kbit and 1Kbit Serial SPI Bus EEPROM With High Speed Clock
• Manufacturer: STMICROELECTRONICS [STMicroelectronics]

SUMMARY DESCRIPTION
The M95040 is a 4 Kbit (512 x 8) electrically eras-
able programmable memory (EEPROM), access-
ed 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 inter-
face that is SPI-compatible. The bus signals are C,
D and Q, as shown in
The device is selected when Chip Select (S) is tak-
en Low. Communications with the device can be
interrupted using Hold (HOLD). WRITE instruc-
tions are disabled by Write Protect (W).
