DESCRIPTION

The CAT24C44 Serial NVRAM is a 256-bit nonvolatile

memory organized as 16 words x 16 bits. The high

speed Static RAM array is bit for bit backed up by a

nonvolatile E

PROM array which allows for easy trans-

fer of data from RAM array to E

PROM (STORE) and

from E

PROM to RAM (RECALL). STORE operations

are completed in 10ms max. and RECALL operations

typically within 1.5µs. The CAT24C44 features unlimited

RAM write operations either through external RAM

writes or internal recalls from E

PROM. Internal false

store protection circuitry prohibits STORE operations

when V

is less than 3.5V (typical) ensuring E

PROM

data integrity.

The CAT24C44 is manufactured using Catalyst’s ad-

vanced CMOS floating gate technology. It is designed to

endure 100,000 program/erase cycles (E

PROM) and

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

in JEDEC approved 8-pin plastic DIP and SOIC pack-

ages.
