The M95128-A125 M95128-A145 is a 128-Kbit serial SPI bus EEPROM produced by ST with a high clock frequency.
The M95128-A125 and M95128-A145 are 128-Kbit serial EEPROM devices designed for automotive applications, complying with the AEC-Q100 grade 0 reliability standard. These devices operate up to 145°C and feature a high-speed Serial Peripheral Interface (SPI) compatible interface running up to 20 MHz.
The memory array consists of 128 Kbits (16384 x 8 bits) organized as 256 pages of 64 bytes, with data integrity improved by an embedded Error Correction Code logic. An additional Identification Page is available to store device identification or sensitive application parameters, which can be permanently locked in read-only mode.
