DESCRIPTION  
The CAT28C17A is a fast, low power, 5V-only CMOS  
parallel EEPROM organized as 2K x 8-bits. It requires  
a simple interface for in-system programming. On-chip  
address and data latches, self-timed write cycle with  
auto-clear and VCC power up/down write protection  
eliminate additional timing and protection hardware.  
DATA Polling and a RDY/BSY pin signal the start and  
end of the self-timed write cycle. Additionally, the  
CAT28C17A features hardware write protection.  
The CAT28C17A is manufactured using Catalyst’s ad-  
vancedCMOSfloatinggatetechnology. Itisdesignedto  
endure 10,000 program/erase cycles and has a data  
retention of 10 years. The device is available in JEDEC  
approved 28-pin DIP and SOIC or 32-pin PLCC pack-  
ages.
