DESCRIPTION  
TheCAT22C10NVRAMisa256-bitnonvolatilememory  
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 1.5µs. 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  
availableinJEDECapproved18-pinplasticDIPand16-  
pin SOIC packages.
