CAV93C66: Microwire Serial CMOS EEPROM, 4 Kb Automotive Grade

The CAV93C66 is a 4 Kb CMOS Serial EEPROM device which is organized as either 256 registers of 16 bits (ORG pin at VCC) or 512 registers of 8 bits (ORG pin at GND). Each register can be written (or read) serially by using the DI (or DO) pin. The device 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.
