Additional Details

The AM28F020-70JC operates from a single 5V power supply and is available in a JEDEC-standard PLCC package. The device features an erase suspend/resume capability, which allows the erase operation to be interrupted so that data can be read from other sectors of the memory. This feature is useful in applications where it is necessary to access critical data during an erase operation. The device also features embedded erase and program algorithms, which simplify memory programming and reduce system overhead.
