CAT28C512/513
512K-Bit CMOS PARALLEL EEPROM
FEATURES
s Fast Read Access Times: 120/150 ns
s Low Power CMOS Dissipation:
–Active: 50 mA Max.
–Standby: 200 µA Max.
s Simple Write Operation:
–On-Chip Address and Data Latches
–Self-Timed Write Cycle with Auto-Clear
s Fast Write Cycle Time:
–5ms Max
s CMOS and TTL Compatible I/O
DESCRIPTION
The CAT28C512/513 is a fast,low power, 5V-only CMOS
parallel EEPROM organized as 64K 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
CAT28C512/513 features hardware and software write
protection.

Temperature Ranges
The CAT28C512/513 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 32-pin DIP, PLCC and TSOP packages.

*COMMENT
Stresses above those listed under Absolute Maximum
Ratingsmay cause permanent damage to the device.
These are stress ratings only, and functional operation
of the device at these or any other conditions outside of
those listed in the operational sections of this specifica-
tion is not implied. Exposure to any absolute maximum
rating for extended periods may affect device perfor-
mance and reliability.

Note:
(1) This parameter is tested initially and after a design or process change that affects the parameter.
(2) The minimum DC input voltage is 0.5V. During transitions, inputs may undershoot to 2.0V for periods of less than 20 ns. Maximum DC
voltage on output pins is VCC +0.5V, which may overshoot to VCC +2.0V for periods of less than 20 ns.
(3) Output shorted for no more than one second. No more than one output shorted at a time.
(4) Latch-up protection is provided for stresses up to 100mA on address and data pins from 1V to VCC +1V.
(5) VILC = 0.3V to +0.3V.
(6) VIHC = VCC 0.3V to VCC +0.3V.
