The Microchip 24LC256T-I/SN is a 256 Kbit serial EEPROM organized as 32K x 8 (32 KB, 32, 768 words) with an I2C two-wire interface, in an 8-pin SOIC package. It operates from 2.5 V to 5.5 V at up to 400 k Hz with a 900 ns access time and approximately 3 mA of supply current. The 24LC256T-I/SN is the industrial temperature grade rated -40°C to 85°C, is lead free and RoHS compliant, and ships on 3, 300-piece tape and reel.

The 24LC256 is one of the most widely designed-in serial EEPROMs, used to store configuration data, calibration tables, device identification, security or licensing keys, and event logs that must persist through power loss. Byte-level rewrite means firmware can change a single setting without a page erase, and the standard 8-pin SOIC pinout is effectively an industry footprint, so it is a common second-source and drop-in choice. The industrial temperature grade extends it to equipment operating outside a controlled environment. Typical buyers span industrial controls, appliances, automotive aftermarket, medical devices, metering, and consumer electronics, along with contract manufacturers building to those designs.
