Additional Details

The X20C04DI provides a 4K bit non-volatile memory storage, organized as 512 bytes of 8 bits each. The device typically uses a serial interface such as SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit) for communication with a microcontroller or other host device. This allows for easy integration with minimal pin count. The EEPROM offers low voltage operation, contributing to low power consumption. It features a high endurance, meaning it can withstand a large number of erase/write cycles. The data retention specification ensures that data is stored reliably for extended periods, even when power is removed. The self-timed write cycle simplifies the programming process. Refer to the datasheet for detailed electrical specifications, timing diagrams, and interface details. The package is usually a DIP (Dual In-line Package) or SOIC (Small Outline Integrated Circuit) for easy PCB mounting.
