32 Kbit I²C EEPROM in a standard SOIC-8 footprint
The STMicroelectronics M24C32-DFMN6TP is a 32 Kbit serial EEPROM with an I²C interface, organized as 4K x 8 bits. It operates at a 1 MHz bus clock, delivering a 450 ns access time and a 5 ms write cycle for page or word writes.
The 5.5 V maximum covers legacy 5 V buses, so it bridges mixed-voltage designs without level shifters.
The laser-etched markings on genuine ST parts have a consistent font and spacing — a quick visual check against a known-good reference is the first screen for incoming inspection.
