Additional Details

The X20C04PI-15 uses a serial interface, such as I2C or SPI, for communication with a microcontroller or other host device. It features a self-timed write cycle, which simplifies the write operation. Detailed timing diagrams, command sets, and application notes are available in the manufacturer's datasheet. The endurance rating indicates the number of write cycles the device can withstand before data retention is compromised. Check the datasheet for specific values.
