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 EEPROM array which allows for easy trans-
fer of data from RAM array to EEPROM (STORE) and
from EEPROM to RAM (RECALL). STORE operations
are completed in 10ms max. and RECALL operations
typically within 1.5
μ
s. The CAT24C44 features unlim-
ited RAM write operations either through external RAM
writes or internal recalls from EEPROM. Internal false
PIN CONFIGURATION
store protection circuitry prohibits STORE operations
when V
CC
is less than 3.5V (typical) ensuring EEPROM
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 (EEPROM) and
has a data retention of 10 years. The device is available
in JEDEC approved 8-pin plastic DIP and SOIC pack-
ages.
