M95320-A125/A145 is a 32Kbit serial SPI bus EEPROM with high-speed clock. It features 32Kbits (4Kbytes) of EEPROM, 32 bytes of page size, 1/4, 1/2 or whole memory write protection, an additional write-lockable page (Identification page), high clock frequency 20MHz (VCC≥4.5V), 10MHz (VCC≥2.5V), 5MHz (VCC≥1.8V), and Schmitt trigger inputs for noise filtering.
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.
