CAT28C17A
16 kb CMOS Parallel
EEPROM
Description
The CAT28C17A is a fast, low power, 5 V−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

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 ON Semiconductor’s
advanced CMOS floating gate technology. It is designed to 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 packages.
