DESCRIPTION

The CAT22C10 NVRAM is a 256-bit nonvolatile memory

organized as 64 words x 4 bits. The high speed Static

RAM array is bit for bit backed up by a nonvolatile

EEPROM array which allows for easy transfer of data

from RAM array to EEPROM (STORE) and from

EEPROM to RAM (RECALL). STORE operations are

completed in 10ms max. and RECALL operations typi-

cally within 1.5

µs. The CAT22C10 features unlimited

RAM write operations either through external RAM

writes or internal recalls from EEPROM. Internal false

store protection circuitry prohibits STORE operations

when VCC is less than 3.0V.

The CAT22C10 is manufactured using Catalyst’s ad-

vanced CMOS floating gate technology. It is designed

to endure 100,000 program/erase cycles (EEPROM)

and has a data retention of 10 years. The device is

available in JEDEC approved 18-pin plastic DIP and 16-

pin SOIC packages.
