Download the CAT93C66 datasheet PDF. This datasheet also covers the CAT93W66 variant, as both devices belong to the same 4kb microwire serial cmos eeprom family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key 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. Features.

CAT93C66 4 kb Microwire Serial CMOS EEPROM Description The CAT93C66 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. Features • High Speed Operation: 2 MHz • 1.8 V to 5.
