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 VCC 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 .
