DESCRIPTION
The CAT28C17A is a fast, low power, 5V-only CMOS
parallel EEPROM organized as 2K 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
CC
power up/down write protection
eliminate additional timing and protection hardware.
DATA
Polling and a RDY/
BSY
pin signal the start and
end of the self-timed write cycle. Additionally, the
CAT28C17A features hardware write protection.
The CAT28C17A is manufactured using Catalyst’s ad-
vanced CMOS floating gate technology. It is designed to
endure 10,000 program/erase cycles and has a data
retention of 10 years. The device is available in JEDEC
approved 28-pin DIP and SOIC or 32-pin PLCC pack-
ages.
