CAT93C46R
1 kb Microwire Serial
EEPROM
Description
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 auto−clear. On−chip
Power−On Reset circuitry protects the internal logic against powering
up in the wrong state.
instruction clock counter which provides improved noise immunity
for Write/Erase commands.
