Description and Introduction

4-MBIT (256K X 16, 512K X 8)SmartVoltage BOOT BLOCK FLASH MEMORY FAMILY The **PA28F400BVB80** is a high-performance flash memory component designed for applications requiring reliable, non-volatile storage. Manufactured using advanced semiconductor technology, this device offers a capacity of 4 megabits (512 KB), organized in a flexible architecture suitable for embedded systems, industrial controls, and telecommunications equipment.  

Operating at a voltage of **5V ± 10%**, the PA28F400BVB80 features fast access times and low power consumption, making it ideal for power-sensitive designs. Its **80ns access speed** ensures efficient data retrieval, while its robust endurance and data retention capabilities support long-term reliability in demanding environments.  

The component employs a **byte-wide parallel interface**, simplifying integration with microcontrollers and processors. Additionally, it supports **block erase and programming operations**, enabling efficient firmware updates and system maintenance. With built-in error correction and wear-leveling algorithms, the PA28F400BVB80 enhances data integrity over extended usage cycles.  

Designed for industrial temperature ranges (**-40°C to +85°C**), this flash memory device meets stringent reliability standards, making it suitable for automotive, aerospace, and industrial automation applications. Its compact **PLCC-32** package ensures space-efficient PCB mounting while maintaining durability in harsh operating conditions.  

The PA28F400BVB80 represents a dependable solution for systems requiring high-speed, non-volatile memory with extended lifecycle support.

Alternative Part Number

  • AM29F400BB-90SC --: Same 4 Mbit flash density and 5 V operation with compatible command set; widely available second-source equivalent.
  • M29F400BB-90N6 --: Pin-compatible 4 Mbit boot-block flash with similar access time and voltage, suitable drop-in replacement.
  • SST39SF040-70-4C-PH --: 4 Mbit 5 V flash in similar package with comparable timing; functional alternative when exact boot-block mapping is not critical.
  • AM29F400BB-90SC --: Pin-compatible 4 Mbit flash memory with similar organization and access time, widely available as a drop-in replacement.
  • M29F400BB-90N6 --: Equivalent 4 Mbit boot-block flash in the same TSOP package with comparable speed and voltage.
  • SST39SF040-70-4C-PHE --: 4 Mbit flash alternative with similar interface; verify timing and package before substitution.
