DESCRIPTION
The CAT28F020 is a high speed 256K x 8-bit electrically erasable and reprogrammable Flash memory ideally suited for applications requiring in-system or after-sale code updates. Electrical erasure of the full memory contents is achieved typically within 0.5 second.
It is pin and Read timing patible with standard EPROM and E2PROM devices. Programming and Erase are performed through an operation and verify algorithm. The instructions are input via the I/O bus, s mercial, industrial and automotive temperature ranges s Stop timer for program/erase s On-chip...
