AM28F020A Datasheet PDF – 2 Megabit Flash Memory – AMD

Part Number: AM28F020A

Function: 2 Megabit (256 K x 8-Bit) CMOS 12.0 Volt, Bulk Erase Flash Memory

Package: DIP, PLCC, TSOP 32 Pin Type

Manufacturer: Advanced Micro Devices


AM28F020A Flash Memory


The Am28F020A is a 2 Megabit Flash memory organized as 256 Kbytes of 8 bits each. AMD’s Flash memories offer the most cost-effective and reliable read/write non-volatile random access memory. The Am28F020A 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 Am28F020A is erased when shipped from the factory. The standard Am28F020A offers access times of as fast as 70 ns, allowing high speed microprocessors to operate without wait states. To eliminate bus conten tion, the device has separate chip enable (CE#) and output enable (OE#) controls.
