DESCRIPTION

store protection circuitry prohibits STORE operations

when V_CCis less than 3.5V (typical) ensuring E²PROM

data integrity.

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 E²PROM array which allows for easy trans-

fer of data from RAM array to E²PROM (STORE) and

from E²PROM to RAM (RECALL). STORE operations

are completed in 10ms max. and RECALL operations

typicallywithin1.5µs.TheCAT24C44featuresunlimited

RAM write operations either through external RAM

writes or internal recalls from E²PROM. Internal false

The CAT24C44 is manufactured using Catalyst’s ad-

vancedCMOSfloatinggatetechnology. Itisdesignedto

endure 100,000 program/erase cycles (E²PROM) and

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

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

ages.
