CAT28C16A
16 kb CMOS Parallel
EEPROM
Description
The CAT28C16A is a fast, low power, 5Vâonly CMOS Parallel
EEPROM organized as 2K x 8âbits. It requires a simple interface for
inâsystem programming. Onâchip address and data latches,
selfâtimed write cycle with autoâclear and VCC power up/down write
protection eliminate additional timing and protection hardware. DATA
Polling signals the start and end of the selfâtimed write cycle.
Additionally, the CAT28C16A features hardware write protection.
The CAT28C16A is manufactured using ON Semiconductorâs
advanced CMOS floating gate technology. It is designed to endure
100,000 program/erase cycles and has a data retention of 100 years.
The device is available in JEDEC approved 24âpin DIP and SOIC or
32âpin PLCC packages.
