描述 Description

The CAT93C56/57 is a 2?kb CMOS Serial EEPROM device which is organized as either 128 registers of 16 bits (ORG pin at VCC) or 256 registers of 8 bits (ORG pin at GND). Each register can be written (or read) serially by using the DI (or DO) pin. The CAT93C56/57 features sequential read and self?timed internal write with auto?clear. On?chip Power?On Reset circuitry protects the internal logic against powering up in the wrong state.
