概要

Description

PC28F128P33T85A is a parallel NOR flash memory device with a capacity of 128 Mbit (about 16 MB). It’s designed for embedded systems to store firmware and data, accessed via a parallel data bus (typically 8-bit) and controlled by CE, OE, and WE signals. The “33” indicates 3.3 V operation, and the “T85A” suffix denotes an industrial temperature range (up to 85°C) and revision/grade.
Common uses include boot code storage, code execution, and non-volatile data retention in microcontroller-based systems. Exact details such as bus width, page/block sizes, access times, endurance, and package options vary by vendor and revision, so consult the official datasheet for the specific part from the supplier. If you share the vendor (e.g., Spansion/Cypress, etc.), I can point you to the precise datasheet and extract the key specs.
