Description and Introduction

64-bit, 66MHz PCI Bus Mastering I/O Accelerator for Motorola PowerQUICC? & Generic 32-bit, 66MHz Local Bus Designs The **PCI9656-BA66BIG** is a high-performance, 64-bit PCI-to-PCI bridge designed to facilitate seamless data transfer between PCI buses in embedded and computing systems. Manufactured by PLX Technology (now part of Broadcom), this component supports both **33 MHz and 66 MHz PCI bus operations**, ensuring compatibility with a wide range of legacy and modern PCI-based devices.  

Equipped with **dual address cycle (DAC) support**, the PCI9656-BA66BIG enables efficient handling of 64-bit addressing, making it ideal for applications requiring large memory spaces. Its **non-transparent bridging (NTB) capability** allows for secure, isolated communication between separate PCI domains, which is particularly useful in fault-tolerant and multi-processor systems.  

The device features **advanced power management**, reducing energy consumption without compromising performance. Its **compact BGA (Ball Grid Array) package** ensures reliable integration into space-constrained designs while maintaining robust signal integrity.  

Common applications include **industrial automation, telecommunications, and high-performance computing**, where reliable PCI bus expansion and bridging are critical. With its combination of speed, flexibility, and power efficiency, the PCI9656-BA66BIG remains a dependable solution for complex PCI-based architectures.  

For detailed technical specifications, consult the official datasheet to ensure proper implementation in system designs.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • PCI9656-BA66BI --: Same PCI9656 66MHz PCI-to-local bus bridge in the same BGA package, differing only in the lead-free/tray suffix, so it is functionally identical and pin-compatible.
  • PCI9056-BA66BI --: Closely related PLX 9056 PCI bridge with the same 66MHz PCI interface and BGA footprint; a common drop-in substitute when the 9656 is unavailable, though firmware may need minor adjustment.
  • PCI9656-BA66BIG --: Broadcom acquired PLX Technology and continues to supply the PCI9656 under the same part number, making this the most reliable sourcing alternative with identical specifications.
  • PCI9656-BA66BI --: Same PCI9656 64-bit PCI-to-PCI bridge in the same BGA package, differing only in the lead-free/tray suffix, so it is a near drop-in replacement.
  • PCI9056-BA66BI --: Closely related PLX 9056 PCI bridge with similar 66 MHz 64-bit PCI interface and BGA footprint; usable where the 9656-specific features are not required.
  • PCI9656-BA66BIG --: PLX was acquired by Broadcom, so the same device is now sourced under the Broadcom brand; functionally identical with updated vendor documentation and lifecycle support.
