The AT24C04C provides 4,096 bits of Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 512 words of 8 bits each. The device’s cascading feature allows up to four devices (AT24C04C) to share a common two-wire bus.
These devices are optimized for use in many industrial and commercial applications where low‑power and low‑voltage operations are essential.
The AT24C04C/AT24C08C operates as a slave device and utilizes a simple I2C-compatible two-wire digital serial interface to communicate with a host controller, commonly referred to as the bus master. The master initiates and controls all read and write operations to the slave devices on the serial bus, and both the master and the slave devices can transmit and receive data on the bus.
