The Microchip AT24C64D-SSHM-T is a 64 kbit serial EEPROM organized as 8K x 8 (8 kB) in an 8-pin SOIC package, supplied on tape and reel. It communicates over a 2-wire I2C interface at clock rates up to 1 MHz and operates from a wide 1.7 V to 5.5 V supply, with a nominal 5 V rating and 3 mA typical supply current. Access time is specified at 550 ns. AT24C64D-SSHM-T is a lead-free, RoHS-compliant surface-mount device rated for -40 C to +85 C operation.

Serial EEPROM is byte-alterable non-volatile memory used to hold small amounts of data that must survive power loss, and the I2C interface lets it share a two-wire bus with other peripherals using only two microcontroller pins. The AT24C64D-SSHM-T is typically used for configuration and calibration storage, board and cable identification data, serial numbers, user settings and event or error logs. Its 1.7 V to 5.5 V range lets the same part serve both low-voltage battery designs and legacy 5 V rails. Buyers are usually embedded designers and EMS providers building industrial controls, consumer devices, networking hardware and automotive-adjacent electronics.
