STMicroelectronics, 4 MB EEPROM, 40 ns 8-Pin TSSOP Serial-SPI

The STMicroelectronics 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 M95M04-A125 and M95M04-A145 offer an additional identification page (512 bytes) in which the ST device identification can be read. This page can also be used to store sensitive application parameters that can later be permanently locked in read-only mode.

• Maximum clock frequency 10 MHz full range of VCC
• Schmitt trigger inputs for noise filtering
• Short write cycle time
• Byte write within 4 ms
• Page write within 4 ms
• ESD Protection (human body model) 4000 V
