DESCRIPTION
The CAT28C65B 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 VCC power up/down write protection
eliminate additional timing and protection hardware.
DATA Polling, a RDY/BUSY pin and Toggle status bits
signal the start and end of the self-timed write cycle.
Additionally, the CAT28C65B features hardware and
software write protection.
The CAT28C65B 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 JEDECapproved 28-pin DIP, 28-pin TSOP, 28-pin SOIC or 32-
pin PLCC packages.
