The STMicroelectronics M24128-BRDW6TP is a 128 Kbit (16 KB) serial EEPROM with a two-wire I2C interface, supplied in an 8-lead TSSOP package on tape and reel. It operates across a wide 1.8 V to 5.5 V supply range at up to 400 k Hz bus frequency, with a 900 ns access time and roughly 2.5 mA of supply current. The M24128-BRDW6TP is rated from -40°C to 85°C, is lead free and RoHS compliant, and is specified for 4 million write cycles.

Serial EEPROM is used for the small blocks of data that must survive power loss and be rewritten byte by byte: calibration constants, serial numbers and board identification, configuration and user settings, operating hours, and event or fault logs. Unlike flash, EEPROM erases and writes at byte granularity, so a design can update a single parameter without managing a page or block. The 1.8 V to 5.5 V range means one part number serves boards on any common logic rail, and the high endurance rating suits counters or logs that are updated frequently. Typical buyers are industrial, appliance, medical, metering, and communications equipment OEMs and their contract manufacturers.
