The M24256-BRMN6TP is a serial EEPROM from STMicroelectronics with a density of 256kb, organised as 32kB, in an 8-pin SOIC package measuring 5mm by 4mm. It communicates over a two-wire I2C serial interface, operates from 1.8 volts to 5.5 volts with a 5-volt nominal supply drawing 2.5 milliamperes, and has an access time of 450 nanoseconds. The M24256-BRMN6TP is specified over -40°C to 85°C, is lead-free and RoHS compliant, and ships in tape-and-reel at 2500 pieces per reel. STMicroelectronics records the manufacturer lifecycle status as not recommended for new designs, which is material for long-term sourcing decisions.

Serial EEPROM is byte-alterable non-volatile memory that retains its contents without power and can be rewritten a byte at a time, which distinguishes it from flash that must be erased in blocks. Devices of this density are used to hold calibration constants, serial numbers and board identity data, configuration and parameter tables, event and error logs, and display or module identification records, communicating over just two signal lines to save microcontroller pins. The wide 1.8-to-5.5-volt supply range on the M24256-BRMN6TP lets one part serve both low-voltage and 5-volt legacy rails. Buyers are embedded systems and industrial module designers, appliance and instrumentation OEMs, and sourcing teams securing last-time-buy coverage on parts flagged as not recommended for new designs.
