CAT28LV64
64 kb CMOS Parallel
EEPROM
Description
The CAT28LV64 is a low voltage, low power, CMOS Parallel
EEPROM organized as 8K x 8−bits. It requires a simple interface for
in−system programming. On−chip address and data latches,

Polling and Toggle status bit signal the start and end of the self−timed
write cycle. Additionally, the CAT28LV64 features hardware and
software write protection.
The CAT28LV64 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 28−pin DIP, 28−pin TSOP,
28−pin SOIC or 32−pin PLCC packages.
