Description

The M95320-A125 and M95320-A145 are 32-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 M95320-A125 and M95320-A145 are byte-alterable

memories (4096 × 8 bits) organized as 128 pages of 32 byte in which the data integrity is

significantly improved with an embedded Error Correction Code logic.

The M95320-A125 and M95320-A145 offer an additional Identification Page (32 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.
