The Atmel AT24C01 is a 1Kbit (128 x 8) Serial EEPROM (Electrically Erasable Programmable Read-Only Memory). It utilizes a simple two-wire serial interface (I2C) for communication and is designed for low-power applications. This EEPROM is typically used for storing small amounts of configuration data, user preferences, or other non-volatile information.

Additional Details
The AT24C01 communicates via the I2C protocol, using a device address for identification on the bus. The write protect feature prevents accidental data corruption. The self-timed write cycle eliminates the need for external timing components. Despite being listed as END-OF-LIFE, the AT24C01 remains a reliable choice for legacy systems requiring a small, low-power EEPROM. It is available in various packages including SOIC and DIP. It is typically programmed using common I2C programmers and development boards.
