  1. 2008/05/03 CAT28C512 - 512K-Bit CMOS PARALLEL EEPROM

 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.
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.
