The Microchip 11LC040T-E/TT is a 4Kbit serial EEPROM that communicates over a single-wire interface, packing 512 x 8 bits of non-volatile storage into a SOT-23-3 package. That third pin is the data line — the other two are supply and ground — which frees up GPIO on a microcontroller compared to a two-wire I²C or SPI part.
