DESCRIPTION

The CAT93C46R is a 1-Kb CMOS Serial EEPROM device which is organized as either 64 registers of 16 bits or 128 registers of 8 bits, as determined by the state of the ORG pin. The CAT93C46R features sequential read and self-timed internal write with autoclear. On-chip 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 for Write/Erase commands.
