Electrical erasure of the full memory contents is achieved typically within 0.5 second. It is pin and Read timing compatible with standard EPROM and E2PROM devices. Programming and Erase are performed through an operation and verify algo- rithm. The instructions are input via the I/O bus, using a two write cycle scheme. Address and Data are latched to free the I/O bus and address bus during the write operation. The CAT28F102 is manufactured using Catalyst’s ad- vanced CMOS floating gate technology. It is designed to endure 100,000 program/erase cycles and has a data retention of 10 years. The device is available in JEDEC approved 40-pin DIP, 44-pin PLCC, or 40-pin TSOP packages.
