CAT28LV65

64 kb CMOS Parallel

EEPROM

Description

The CAT28LV65 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,

self−timed write cycle with auto−clear and VCC power up/down write

protection eliminate additional timing and protection hardware. DATA

Polling, RDY/BUSY and Toggle status bit signal the start and end of

the self−timed write cycle. Additionally, the CAT28LV65 features

hardware and software write protection.

The CAT28LV65 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.
