Product Overview
The AT24C04D-SSHM-T from Microchip Technology is a 4Kbit (512 x 8) I2C serial EEPROM in an SOIC-8 package. The D denotes the enhanced version with 1 million erase cycles, SSHM denotes SOIC-8, T denotes tape and reel. Operating from 1.7V to 5.5V with 1MHz I2C at 5V, it provides reliable non-volatile storage for configuration and calibration data.
