Description and Introduction

4-MBIT (256K X 16, 512K X 8)SmartVoltage BOOT BLOCK FLASH MEMORY FAMILY The **PA28F400BVB120** is a high-performance flash memory component designed for applications requiring reliable, non-volatile data storage. This electronic device features a 4-megabit (512K x 8) capacity, making it suitable for embedded systems, industrial controls, and telecommunications equipment where data integrity and fast access are critical.  

Built with advanced CMOS technology, the PA28F400BVB120 offers fast read and write operations, ensuring efficient performance in demanding environments. It supports a wide voltage range and includes built-in error correction mechanisms to enhance data reliability. The component is housed in a 120-ball BGA (Ball Grid Array) package, providing a compact footprint while maintaining robust connectivity.  

Key features include low power consumption, extended endurance cycles, and compatibility with industry-standard interfaces, making it a versatile choice for system designers. Its ability to retain data without power makes it ideal for firmware storage, configuration settings, and other critical functions.  

Engineers and developers seeking dependable flash memory solutions will find the PA28F400BVB120 well-suited for applications that demand durability, speed, and long-term data retention. Its technical specifications and design considerations align with modern electronic system requirements, ensuring seamless integration into various hardware architectures.

Alternative Part Number

  • AM29F400BB-120SC --: Pin-compatible 4 Mbit 5V flash in the same TSOP/PLCC footprint with 120 ns access time, widely available as a drop-in replacement for the Intel 28F400.
  • M29F400BB-120N1 --: Equivalent 4 Mbit boot-block flash with 120 ns speed and compatible command set, suitable for direct substitution in most legacy designs.
  • SST39SF040-70-4C-PHE --: 4 Mbit 5V parallel flash with similar pinout and faster 70 ns access, usable as a functional replacement where timing is not critical.
  • AM29F400BB-120SC --: Same 4 Mbit 5V NOR flash density and 120 ns speed grade, pin-compatible x8/x16 interface, widely available as a direct substitute.
  • M29F400BB-120N1 --: Equivalent 4 Mbit 5V parallel NOR flash with 120 ns access time and matching TSOP/PLCC pinout, suitable drop-in replacement.
  • SST39SF040-70-4C-PHE --: 4 Mbit 5V parallel NOR flash with faster 70 ns access, software-compatible command set and common PLCC package, good fallback option.
