Overview
The onsemi CAT93C56VI-G is a 2-Kb Microwire Serial CMOS EEPROM designed for applications requiring non-volatile memory. This device operates on a single power supply and generates the high voltage required for write operations internally. It is organized as either 128 registers of 16 bits or 256 registers of 8 bits, depending on the state of the ORG pin. The CAT93C56VI-G features high-speed operation, low power consumption, and robust reliability characteristics, making it suitable for a wide range of industrial and extended temperature applications.
