Description: 2 Megabit CMOS Flash Memory

Features

* s Fast read access time: 90/120 ns s Low power CMOS dissipation:
* Active: 30 mA max (CMOS/TTL levels)
* Standby: 1 mA max (TTL levels)
* Standby: 100 µA max (CMOS levels) s High speed programming:
* 10 µs per byte
* 4 seconds typical chip program s 0.5 second

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 compatible with standard EPROM and E2PROM devices. Programming and Erase are performed through an operation and verify algorithm. The inst
