32Kbit SPI EEPROM for automotive ECU parameter storage
The STMicroelectronics M95320-DRMN3TP/K is a 32Kbit serial EEPROM with an SPI interface, part of the AEC-Q100 qualified Automotive series. It stores calibration maps, configuration parameters, and fault logs in engine control units, transmission controllers, and ADAS modules where non-volatile memory must survive 125°C under-hood temperatures. The 20 MHz clock rate keeps read/write latency low enough for boot-time parameter fetch without delaying system startup.
