Additional Details

The X2816CJI-20 operates from a single 5V power supply and features TTL-compatible inputs and outputs for easy interfacing with other digital circuits. It supports both byte-wide and page-wide write operations, allowing for efficient data storage and retrieval. The automatic page write operation simplifies the write process by automatically handling the timing and control signals required for writing an entire page of data. The device typically has a specified endurance of 10,000 erase/write cycles per byte. The X2816CJI-20 is commonly used to store configuration parameters, calibration data, or firmware code that needs to be updated periodically.

The JEDEC standard 28-pin DIP package allows for easy integration into existing systems. The EEPROM’s non-volatility ensures that data is preserved even during power outages, making it suitable for critical applications where data loss is unacceptable. The fast access time ensures that data can be read and written quickly, minimizing delays in the system. The device’s datasheet provides detailed information on the timing requirements, power consumption, and other electrical characteristics, which are essential for designing reliable and efficient systems. The X2816CJI-20 offers a cost-effective solution for non-volatile data storage in a variety of applications.

Its ease of use and robust performance makes it a popular choice for both new designs and legacy system upgrades. The ability to erase and reprogram the EEPROM electrically allows for easy updates and modifications to the stored data, without requiring physical removal of the device from the circuit board.
