Product overview

概要

The M95320-A125 and M95320-A145 are 32-Kbit serial electrically erasable programmable memory (EEPROM) automotive grade devices capable of 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. The M95320-A125 and M95320-A145 are byte-alterable memories (4096 × 8 bits) organized as 128 pages of 32 bytes 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 bytes), in which the ST device identification can be read. This page can also store sensitive application parameters, which can later be permanently locked in read-only mode.
