Description

The CAV93C66 is an EEPROM Serial 4−Kb Microwire

Automotive Grade 1 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.
