The Microchip 24FC512T-E/Q4B is a 512Kbit serial EEPROM organized as 64K x 8, communicating over an I²C bus at up to 1 MHz.
Housed in an 8-UDFN with exposed pad (supplier package 8-UDFN 2x3 mm), the part mounts flush to the PCB.
The 24AA128T-I/SN is a smaller-density sibling (128Kbit vs 512Kbit) with the same 900 ns access time and I²C interface, but its operating temperature tops out at 85°C — it does not meet the 125°C automotive grade.
ROHS3 compliance is confirmed. The AEC-Q100 automotive qualification is the primary reliability document — this covers the temperature grade, ESD sensitivity, and PPAP-level data for tier-one ECU programs.
