GENERAL DESCRIPTION
The Am28F256 is a 256 K Flash memory organized as 32 Kbytes of 8 bits each. AMD’s Flash memories offer the most cost-effective and reliable read/write non volatile random access memory. The Am28F256 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 Am28F256 is erased when shipped from the factory.
