Additional Details

The AT24C04-10PU-1.8 utilizes a two-wire serial interface (I2C) for communication with a host microcontroller. The device supports standard I2C addressing and provides a self-timed write cycle, which simplifies the write operation and reduces the need for external timing control. The write protect pin allows the user to disable write operations to the EEPROM, preventing accidental data corruption. The AT24C04-10PU-1.8 is designed for high reliability, with a minimum of 1,000,000 write cycles and a data retention period of 100 years. It is available in DIP and SOIC packages.
