Datasheet Summary
CAT93C56, CAT93C57
2-Kb Microwire Serial CMOS EEPROM
CAT93C57 Not Remended for New Designs: Replace with CAT93C56
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.
