32 Kbit automotive EEPROM with 1 MHz I2C and 450 ns access
The STMicroelectronics M24C32-DRMN3TP/K is a 32 Kbit serial EEPROM organized as 4K x 8 bits, accessed via an I2C interface running at up to 1 MHz. The 450 ns access time and 4 ms write cycle per word/page keep bus transactions predictable for calibration storage, fault-logging, and configuration parameters in engine control units, transmission controllers, and ADAS modules.
For dual-sourcing, the M24C32-DRDW3TP/K (same 32 Kbit frame, same AEC-Q100 grade, same 1 MHz I2C, same 450 ns access) is a functional drop-in in a different package variant — qualify it early if you want a second supply leg.
