GENERAL DESCRIPTION

The Am28F010A is a 1 Megabit Flash memory organized as 128 Kbytes of 8 bits each. AMD’s Flash memories offer the most cost-effective and reliable read/write non-volatile random access memory. The Am28F010A is packaged in 32-pin PDIP, PLCC, and TSOP versions. It is designed to be reprogrammed and erased in-system or in standard EPROM programmers. The Am28F010A is erased when shipped from the factory.
