Flash Memory Cross Reference Guide

This document provides a comparison of flash memory chips from various manufacturers including AMD, Atmel, ST Micro, and SST. It lists the chip density, manufacturer, part number, voltage, speed, description, package type, and equivalent Winbond part number. For many chips, the Winbond part is listed as a drop-in replacement with the same pinout and software compatibility. However, some chips require software changes due to differences in features like sector size. The document serves as a guide for finding compatible flash chips from Winbond.
