Additional Details

The X24C45PI typically operates from a 5V power supply. It uses a 2-wire serial interface (I2C compatible) for communication, allowing for easy interfacing with microcontrollers. The device is available in a PDIP (Plastic Dual In-line Package) package, making it suitable for through-hole mounting. It has a typical write cycle time of around 5 ms. The device offers high data retention, typically specified as 100 years. It supports a limited number of write cycles, usually around 10,000 cycles per byte. Understanding the write cycle limitations is essential for maximizing the lifespan of the device in applications involving frequent data updates. Proper decoupling capacitors should be used to minimize noise and ensure reliable operation. The X24C45PI is commonly used in applications where a small amount of non-volatile memory is needed for storing configuration settings or calibration data.
