Description and Introduction

PCI Bus Master I/O Accelerator Chip The **PCI9054-AC50PIF** is a high-performance PCI bus interface chip designed to facilitate seamless communication between peripheral devices and a host system via the PCI (Peripheral Component Interconnect) bus. Manufactured by PLX Technology (now part of Broadcom), this component is widely used in embedded systems, industrial automation, and data acquisition applications where reliable and efficient data transfer is essential.  

Featuring a 32-bit, 33/66 MHz PCI interface, the **PCI9054-AC50PIF** supports both master and target modes, enabling flexible system integration. It includes a local bus interface that can be configured for various microprocessor architectures, making it compatible with a broad range of designs. The chip also incorporates advanced features such as scatter-gather DMA (Direct Memory Access), which enhances data throughput by minimizing CPU overhead.  

With its robust architecture and low power consumption, the **PCI9054-AC50PIF** is well-suited for demanding environments. Its ability to handle high-speed data transfers while maintaining signal integrity makes it a preferred choice for developers working on complex PCI-based systems. Whether used in medical equipment, telecommunications, or industrial control systems, this component delivers reliable performance and scalability.  

Engineers appreciate its ease of integration and comprehensive documentation, which streamline the development process while ensuring compliance with industry standards.

Application Scenarios & Design Considerations

PCI Bus Master I/O Accelerator Chip

Alternative Part Number

  • PCI9054-AC50BI --: Same PCI9054 bridge family in the same AC package but rated for industrial temperature range, making it a direct functional replacement for the PIF industrial-grade part.
  • PCI9054-AB50PI --: PCI9054 variant in the AB package with 50 MHz clock and industrial temperature rating; electrically compatible with the AC50PIF for most designs, differing mainly in package style.
  • PCI9056-BA66BI --: Next-generation PLX PCI-to-local bus bridge offering similar PCI 2.2 functionality and higher clock support; usable as an upgrade path when minor board rework is acceptable.
  • PCI9054-AC50PI --: Same PCI9054 series and 50 MHz speed grade in a 208-pin PQFP package, but without the lead-free/industrial suffix; functionally equivalent and widely available as a drop-in replacement.
  • PCI9054-AB50PI --: Same PCI9054 bridge family and 50 MHz rating in the same package, differing only in the silicon revision letter; compatible in most designs and often stocked as an alternative to the AC revision.
  • PCI9052 --: Related PLX PCI bridge from the same product line with similar PCI-to-local bus functionality; a viable fallback when PCI9054 variants are unavailable, though pinout and feature differences require design review.
