AEC-Q100 64Kbit I²C EEPROM for under-hood and chassis-domain storage
The STMicroelectronics M24C64-DRDW3TP/K is a 64Kbit serial EEPROM from the Automotive AEC-Q100 series, organized as 8K x 8 bits and accessed through an I²C interface at up to 1 MHz.
The wide supply range covers both legacy 5V buses and modern 3.3V or 1.8V logic without a level translator. At 1.8V the I²C timing still meets the 1 MHz specification, though the 450 ns access time is a datasheet maximum across the full voltage range — budget accordingly for the slowest corner.
The ROHS3 compliance is confirmed.
