Address and Data are latched The CAT28F512 is a high speed 64K x 8-bit electrically to free the I/O bus and address bus during the write erasable and reprogrammable Flash memory ideally operation. suited for applications requiring in-system or after-sale code updates. Electrical erasure of the full memory The CAT28F512 is manufactured using Catalysts ad- contents is achieved typically within 0.5 second. vanced CMOS floating gate technology. It is designed to endure 100,000 program/erase cycles and has a data It is pin and Read timing compatible with standard retention of 10 years. The device is available in JEDEC EPROM and EEPROM devices. Programming and Erase approved 32-pin plastic DIP, 32-pin PLCC or 32-pin are performed through an operation and verify algo- TSOP packages. rithm.
