The STMicroelectronics M24C02-FMN6TP is a 2Kbit serial EEPROM with an I²C interface, organized as 256 x 8 bits. The 400 kHz bus clock and 900 ns access time are standard for this density class; the 5 ms page/word write cycle is the spec to budget for in a firmware update or calibration-storage routine.
It belongs in outdoor telecom cabinets, factory-floor sensors, engine-bay-adjacent electronics (not directly under-hood), and any sealed enclosure where the internal air hits that band.
