M95M04-DR - STMicroelectronics

M95M04-DR 4-Mbit serial SPI bus EEPROM

1 Description The M95M04-DR device is electrically erasable programmable memory (EEPROM) organized as 524288 x 8 bits, accessed through the SPI bus. The M95M04-DR can operate with a supply range from 1.8 to 5.5 V, and is guaranteed over the -40 °C/+85 °C temperature range. The M95M04-DR offer an additional page, named the identification page (512 bytes). .
