Product Summary
The AM28F256-150PC is a 256 K Flash memory organized as 32 Kbytes of 8 bits each. AMDs Flash memories offer the most cost-effective and reliable read/write nonvolatile random access memory. The AM28F256-150PC 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. The AM28F256-150PC is byte programmable using 10 μs programming pulses in accordance with AMDs Flashrite programming algorithm. The typical room temperature programming time of the AM28F256-150PC is a half a second. The entire chip is bulk erased using 10 ms erase pulses according to AMDs Flasherase alrogithm. Typical erasure at room temperature is accomplished in less than one second. The windowed package and the 15-20 minutes required for EPROM erasure using ultra-violet light are eliminated.
