The X24C01SI-3T1 is available in an 8-pin SOIC package and is designed to operate over a wide temperature range. The device supports a supply voltage of 2.7V to 5.5V and has a typical write cycle time of 5ms. It is commonly used in applications where a small amount of non-volatile memory is needed and ease of interfacing is important. The I2C interface uses two pins – SDA (Serial Data) and SCL (Serial Clock) – to communicate with a host microcontroller. This EEPROM can be protected from unwanted write operations to the memory array, enhancing data integrity. The device uses a two-wire interface that allows for efficient data transfer with minimal overhead. Its low power consumption makes it ideal for portable or battery-powered applications, ensuring prolonged operational lifespan without requiring frequent battery replacements.
