Description and Introduction

4-MBIT (256K X 16, 512K X 8)SmartVoltage BOOT BLOCK FLASH MEMORY FAMILY The **Intel PA28F400BVT80** is a high-performance flash memory component designed for applications requiring reliable, non-volatile storage. As part of Intel's advanced memory lineup, this device offers a capacity of 4 megabits (512 KB) and operates at a voltage of 5V, ensuring compatibility with a wide range of industrial and embedded systems.  

Built with a **Top Boot Block architecture**, the PA28F400BVT80 provides flexible sector organization, making it suitable for firmware storage, configuration data, and code execution in place (XIP) applications. Its **80ns access time** ensures efficient data retrieval, while the extended temperature range (-40°C to +85°C) enhances its suitability for harsh environments.  

The component supports **standard microprocessor interfaces**, simplifying integration into existing designs. Additionally, it features **hardware and software data protection** mechanisms, safeguarding critical information from accidental corruption.  

With its robust design and dependable performance, the Intel PA28F400BVT80 remains a practical choice for legacy systems and applications where durability and long-term reliability are essential. Its combination of speed, endurance, and sector flexibility makes it a versatile solution for embedded developers and industrial applications.
