CAT93C57
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.
