CAT28C16A
16 kb CMOS Parallel
EEPROM
Description
The CAT28C16A 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 signals the start and end of the self−timed write cycle.
Additionally, the CAT28C16A features hardware write protection.
The CAT28C16A is manufactured using ON Semiconductor’s
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 24−pin DIP and SOIC or
32−pin PLCC packages.
