M29W800A - 8 Mbit (1M x8 or 512K x16) 3V Supply Flash Memory

Overview

The M29W800A is a high-performance, non-volatile flash memory device that offers flexible erase and programming capabilities. It supports both byte-wide (x8) and word-wide (x16) configurations, making it suitable for a wide range of embedded applications. With a single voltage supply requirement of 2.7V to 3.6V, it is ideal for low-power systems while maintaining high-speed operation.

This device features a block-erasable architecture, allowing for efficient memory management. It can be erased at either the block level or the entire chip level, providing flexibility for different use cases. The in-system programmability enables easy updates without requiring removal from the target system.
