DESCRIPTION

The CAT28C64B is a fast, low power, 5V-only 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 V

power up/down write protection

eliminate additional timing and protection hardware.

DATA

Polling and Toggle status bits signal the start and

end of the self-timed write cycle. Additionally, the

CAT28C64B features hardware and software write

protection.

The CAT28C64B is manufactured using Catalyst’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, TSOP, SOIC, or, 32-pin PLCC

package .
