M95M02-A125：Automotive 2048 Kbit SPI bus EEPROM with high speed clock

The M95M02-A125 is 2-Mbit serial EEPROM Automotive grade device operating up to 125°C. The M95M02-A125 is compliant with the very high level of reliability defined by the Automotive standard AEC-Q100 grade 0.

The device is accessed by a simple serial SPI compatible interface running up to 10 MHz.

The memory array is based on advanced true EEPROM technology (Electrically Erasable PROgrammable Memory). The M95M02-A125 is byte-alterable memories (262144 × 8 bits) organized as 1024 pages of 256 byte in which the data integrity is significantly improved with an embedded Error Correction Code logic.

The M95M02-A125 offers an additional Identification Page (256 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.
