ON Semiconductor CAT93C57LI-G EEPROM

The CAT93C57LI-G is a high-performance EEPROM (Electrically Erasable Programmable Read-Only Memory) device from ON Semiconductor, designed to provide a robust storage solution for a wide array of electronic applications. This EEPROM offers a 2K-bit (256 x 8 or 128 x 16) memory capacity, making it ideal for storing firmware, configuration parameters, calibration data, and other critical information that must be preserved across power cycles.

One of the key features of the CAT93C57LI-G is its versatility in terms of data organization. Users can select between an 8-bit or 16-bit data word size, providing flexibility to match the specific requirements of their application. The device operates over a voltage range of 2.5V to 5.5V, ensuring compatibility with both low-power and standard digital logic levels, making it a suitable choice for battery-operated devices as well as more traditional powered systems.

ON Semiconductor has equipped the CAT93C57LI-G with a robust set of features to ensure data integrity and ease of use. The EEPROM supports a fast write cycle time of 5 ms, allowing for quick updates to stored data. Additionally, the device is designed with a self-timed write cycle, including auto-erase and auto-write capabilities, which simplifies the programming process and reduces the risk of data corruption.

The CAT93C57LI-G also offers a high level of data protection. It includes hardware and software write protection mechanisms to prevent inadvertent writes that could otherwise compromise the stored data. The device is also built to withstand harsh conditions, with an operating temperature range of -40°C to +85°C, ensuring reliable performance in challenging environments.

Communication with the CAT93C57LI-G is facilitated through a simple and efficient 3-wire serial interface, compatible with SPI protocols, which allows for easy integration into existing designs. The device is available in a compact 8-lead PDIP package, making it suitable for space-constrained applications while providing a reliable connection for PCB mounting.

In summary, the ON Semiconductor CAT93C57LI-G EEPROM is an excellent choice for designers looking for a dependable and flexible non-volatile memory solution that can be easily incorporated into a wide range of electronic systems.
