DESCRIPTION

The CAT28C64B is manufactured using Catalyst’s ad-

vancedCMOSfloatinggatetechnology. Itisdesignedto

endure 100,000 program/erase cycles and has a data

retentionof100years.ThedeviceisavailableinJEDEC-

approved28-pinDIP,28-pinTSOP,28-pinSOIC,or,32-

pin PLCC package .

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

Parallel E²PROM 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_CCpower 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 pro-

tection.
