  • The M95256-A125 and M95256-A145 are 256-Kbit 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 up to 20 MHz.
    The memory array is based on advanced true EEPROM technology (Electrically Erasable PROgrammable Memory). The M95256-A125 and M95256-A145 are byte-alterable memories (32768 × 8 bits) organized as 512 pages of 64 byte in which the data integrity is significantly improved with an embedded Error Correction Code logic.
    The M95256-A125 and M95256-A145 offer an additional Identification Page (64 byte) in which the ST device identification can be read. This page can also be used to store sensitive application parameters which can be later permanently locked in read-only mode.
