512K-Bit CMOS PARALLEL EEPROM
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:
s CMOS and TTL Compatible I/O
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
s Automatic Page Write Operation:
–1 to 128 Bytes in 5ms
–Page Load Timer
s End of Write Detection:
s Hardware and Software Write Protection
s 100,000 Program/Erase Cycles
s 100 Year Data Retention
s Commercial, Industrial and Automotive
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.
