Description and Introduction

32-bit, 66MHz PCI Bus Mastering I/O Accelerator for Motorola PowerQUICC? and Generic 32-bit, 66MHz Local Bus Designs The **PCI9056-BA66BIG** is a high-performance PCI bus target interface chip designed to facilitate seamless communication between peripheral devices and PCI-based systems. Manufactured by PLX Technology (now part of Broadcom Inc.), this component is widely used in embedded systems, industrial automation, and data acquisition applications due to its reliability and advanced features.  

Featuring a 32-bit, 66 MHz PCI interface, the PCI9056-BA66BIG supports high-speed data transfers, making it ideal for applications requiring efficient bus mastering and DMA (Direct Memory Access) operations. Its flexible architecture allows for easy integration with various microprocessors and FPGAs, enabling designers to develop customized solutions without extensive hardware modifications.  

Key functionalities include programmable local bus support, interrupt handling, and power management, ensuring compatibility with diverse system requirements. The chip also incorporates robust error detection and recovery mechanisms, enhancing system stability in demanding environments.  

With its compact form factor and low power consumption, the PCI9056-BA66BIG is a preferred choice for developers seeking a dependable PCI interface solution. Its versatility and performance make it well-suited for applications in telecommunications, medical devices, and test equipment, where precision and speed are critical.  

In summary, the PCI9056-BA66BIG offers a reliable and efficient bridge between PCI-based systems and peripheral devices, streamlining development and improving overall system performance.

Application Scenarios & Design Considerations

32-bit, 66MHz PCI Bus Mastering I/O Accelerator for Motorola PowerQUICC? and Generic 32-bit, 66MHz Local Bus Designs

Alternative Part Number

  • PCI9056-BA66BI --: Same PCI9056 66MHz PCI-to-local bus bridge in the same BGA package; the G suffix denotes lead-free/RoHS packing, so the non-G variant is functionally identical and widely available.
  • PCI9054-AC50PI --: Closely related PLX PCI9054 PCI-to-local bus bridge with similar host interface and DMA features; a common drop-in choice when the 9056 is unavailable, though pinout and speed differ so layout review is required.
  • PCI9030-AA60PI --: PLX PCI9030 PCI-to-local bus target bridge offering a comparable PCI interface for many designs; usable as a functional substitute in less demanding applications after verifying bus width and package compatibility.
  • PCI9056-BA66BI --: Same PCI9056 series and 66 MHz bus interface in the same BGA package, differing only in the lead-free/tray suffix, so it is a near drop-in replacement.
  • PCI9054-AC50PI --: Closely related PLX PCI bridge family with similar PCI-to-local bus architecture; usable when the 66 MHz and specific local bus features of the PCI9056 are not strictly required.
  • PCI9656-BA66BI --: Higher-performance member of the same PLX 96xx PCI bridge family with a compatible BGA footprint and 66 MHz support, suitable as an upgrade path with minor design review.
