Overview
CAT28C16A 16K-Bit CMOS PARALLEL E2PROM FEATURES s Fast Read Access Times: 200 ns s Low Power CMOS Dissipation: s End of Write Detection: DATA Polling s Hardware Write Protection s CMOS and TTL Compatible I/O s 10,000 Program/Erase Cycles s 10 Year Data Retention s Commercial, Industrial and Automotive –Active: 25 mA Max.
–Standby: 100 µA Max.
s Simple Write Operation: –On-Chip Address and Data Latches –Self-Timed Write Cycle with Auto-Clear s Fast Write Cycle Time: 10ms Max Temperature Ranges DESCRIPTION The CAT28C16A is a fast, low power, 5V-only CMOS Parallel E2PROM 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 VCC power up/down write protection eliminate additional timing and protection hardware.
DATA Polling signals the start and end of the self-timed write cycle.
Additionally, the CAT28C16A features hardware write protection.
The CAT28C16A is manufactured using Catalyst’s advanced 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 24-pin DIP and SOIC or 32-pin PLCC packages.
