Description

The CAT28F020 is a high speed 256K x 8-bit electricallyerasable and reprogrammable Flash memory ideallysuited for applications requiring in-system or after-salecode updates. Electrical erasure of the full memorycontents is achieved typically within 0.5 second.It is pin and Read timing compatible with standardEPROM and E2PROM devices. Programming andErase are performed through an operation and verifyalgorithm. The instructions are input via the I/O bus,using a two write cycle scheme. Address and Data arelatched to free the I/O bus and address bus during thewrite operation.The CAT28F020 is manufactured using Catalyst’sadvanced CMOS floating gate technology. It is designedto endure 100,000 program/erase cycles and has a dataretention of 10 years. The device is available in JEDECapproved 32-pin plastic DIP, 32-pin PLCC or 32-pinTSOP packages. CAT28F020 Features • Fast read access time: 90/120 ns• Low power CMOS dissipation:– Active: 30 mA max (CMOS/TTL levels)– Standby: 1 mA max (TTL levels)– Standby: 100 μA max (CMOS levels)• High speed programming:– 10 μs per byte– 4 seconds typical chip program• 0.5 seconds typical chip-erase• 12.0V ± 5% programming and erase voltage• Commercial, industrial and automotivetemperature ranges• Stop timer for program/erase• On-chip address and data latches• JEDEC standard pinouts:– 32-pin DIP– 32-pin PLCC– 32-pin TSOP (8 x 20)• 100,000 program/erase cycles• 10 year data retention• Electronic signature
