AM28F512A Datasheet PDF – 512 Kbit Flash Memory – AMD

What is AM28F512A?

This is a type of flash memory device produced by AMD (now Spansion). It has a capacity of 512 kilobits (Kb) or 64 kilobytes (KB) and is organized as 64 kilobytes of 8-bit data. Flash memory is a type of non-volatile memory that can retain data even when power is removed.

The AM28F512A flash memory device is designed for use in a variety of electronic systems, including embedded systems, computer peripherals, and automotive applications. It has a fast access time and a low power consumption, making it suitable for use in battery-powered devices.

Function: 512 Kilobit (64 K x 8-Bit) CMOS 12.0 Volt, Bulk Erase Flash Memory

Package: DIP, PLCC, TSOP 32 Pin Type

Manufacturer: Advanced Micro Devices


AM28F512A datasheet



The Am28F512A is a 512 Kbit Flash memory organized as 64 Kbytes of 8 bits each. AMD’s Flash memories offer the most cost-effective and reliable read/write non- volatile random access memory. It 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 Am28F512A is erased when shipped from the factory. The standard Am28F512A offers access times as fast as 70 ns, allowing operation of high-speed microprocessors without wait states. To eliminate bus contention, It has separate chip enable (CE#) and output enable (OE#) controls.
