The CAT93C56VI-GT3 is an EEPROM (electrically erasable programmable read-only memory) from ON Semiconductor. It is an 8-pin, 2K-bit serial EEPROM, which supports the Microwire bus protocol. The EEPROM is ideal for programs and data within 8-bit microcontrollers that require small storage sizes. It is capable of storing and retrieving data quickly and efficiently. It also features write protection of all data, an unlimited number of write cycles to each memory location, and a write cycle time of 5 ms. Additionally, the CAT93C56VI-GT3 is stored in a plastic DIP package.
