DESCRIPTION  
store protection circuitry prohibits STORE operations  
when VCC is less than 3.5V (typical) ensuring EEPROM  
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 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 1.5µs. The CAT24C44 features unlim-  
ited RAM write operations either through external RAM  
writes or internal recalls from EEPROM. Internal false  
The CAT24C44 is manufactured using Catalyst’s ad-  
vancedCMOSfloatinggatetechnology.Itisdesignedto  
endure 100,000 program/erase cycles (EEPROM) and  
has a data retention of 10 years. The device is available  
in JEDEC approved 8-lead plastic DIP and SOIC  
packages.
