93C57 2K-Bit Microwire Serial EEPROM

The CAT93C56/57 are 2K-bit Serial EEPROM memory devices which are configured as either registers of 16 bits (ORG pin at VCC) or 8 bits (ORG pin at GND). Each register can be written (or read) serially by using the DI (or DO) pin. The CAT93C56/57 are manufactured using Catalyst’s advanced CMOS EEPROM floating gate technology. The devices are designed to endur.
