AT24C04

The AT24C04 is a 4Kb (512 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) organized as 512 words of 8 bits each. Manufactured by Microchip Technology Inc., this EEPROM utilizes an I2C (Inter-Integrated Circuit) interface for communication, making it ideal for use in a wide range of applications where non-volatile memory storage is required. The AT24C04 offers high reliability, low power consumption, and the capability for byte and page write operations.
