CAT93C46R EEPROM Serial 1-Kb Microwire Description The CAT93C46R is a 1Kb Microwire Serial EEPROM device which is organized as either 64 registers of 16 bits or 128 registers of 8 www.onsemi.com bits, as determined by the state of the ORG pin. The CAT93C46R features sequential read and selftimed internal write with autoclear. Onchip Power On Reset circuitry protects the internal logic against powering up in the wrong state. In contrast to the CAT93C46, the CAT93C46R features an internal instruction clock counter which provides improved noise immunity PDIP8 TSSOP8 for Write/Erase commands.
