2-Kb Microwire Serial CMOS EEPROM

FEATURES

DESCRIPTION

The CAT93C56/57 is a 2-Kb CMOS Serial EEPROM

device which is organized as either 128 registers of 16

bits (ORG pin at V_CC) or 256 registers of 8 bits (ORG pin

at GND). Each register can be written (or read) serially

by using the DI (or DO) pin. The CAT93C56/57 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.

High speed operation: 2MHz

1.8V to 5.5V supply voltage range

Selectable x8 or x16 memory organization

Sequential read

Software write protection

Power-up inadvertant write protection

Low power CMOS technology

1,000,000 Program/erase cycles

100 year data retention

Industrial temperature ranges
