The STMicroelectronics M24512-DFMC6TG is a 512Kbit serial EEPROM organized as 64K x 8, giving 64kB of byte-addressable non-volatile storage over an I2C bus. It supports clock frequencies up to 1M Hz with a 500ns access time and operates from a wide 1.7V to 5.5V supply, drawing 5mA nominal. The device is supplied in an 8-pin UFDFPN package just 600µm high and is rated for -40°C to 85°C. M24512-DFMC6TG is an active production part in the ST M24512 series.

Serial EEPROM provides small-capacity non-volatile storage that can be rewritten byte by byte, which is what distinguishes it from flash memory that must be erased in blocks. That makes it the standard choice for configuration data, calibration constants, serial numbers, event counters, and settings that must survive power loss and change over a product life. The two-wire I2C interface needs only two pins on the host controller, and the 1.7V to 5.5V range lets one part serve both low-voltage and legacy 5V rails. Devices in this class are designed into industrial and automotive control boards, medical and test instruments, appliances, networking equipment, and consumer electronics, typically alongside a microcontroller that has no on-chip non-volatile storage to spare.
