AT24C04D in 24LCxx / AT24Cxx I2C EEPROM Family
The AT24C04D series from Microchip Technology is a 4-Kbit serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 512 words of 8 bits each. Operating on an I2C (2-wire) serial interface, these devices support a wide voltage range from 1.7V to 3.6V. They are designed for industrial and commercial applications requiring low-power and low-voltage operation, offering a reliable solution for non-volatile data storage with 100-year data retention and high endurance.
