M95M04-A145 - STMicroelectronics

M95M04-A145 Automotive 4-Mbit serial SPI bus EEPROM

1 Description The M95M04-A125 and M95M04-A145 are 4 Mbit serial EEPROM automotive grade devices operating up to 145 °C. They are compliant with the very high level of reliability defined by the automotive standard AEC-Q100 grade 0. The devices are accessed by a simple serial SPI compatible interface running at up to 10 MHz. The memory array is based on ad.
