CAT28F020 Datasheet (Catalyst Semiconductor) - 2 Megabit CMOS Flash Memory

CAT28F020, 2 Megabit CMOS Flash Memory

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 compatibl
