PCI9056-BA66BI G

Specialized Overview

The PCI9056-BA66BI G is a 32-bit, 66MHz PCI Bus Mastering I/O Accelerator designed for Motorola PowerQUICC and generic local bus architectures. It operates at a maximum clock frequency of 66 MHz with a data rate of 2112 Mb/s. The device utilizes a 256-ball PBGA package measuring 17 x 17 mm with a 1.00 mm pitch. Electrical specifications include a minimum and maximum power supply voltage of 2.5 V, with an operating temperature range from -40°C to +85°C. It supports 32-bit data bus width and features 3.3V I/O that is 5V tolerant.

Specialized Feature Summary

• Supports PICMG 2.1 r2.0 Hot Swap Silicon capabilities including Bias Voltage and Early Power support
• Incorporates Data Pipe Architecture technology for high-speed DMA and direct master/slave transfers
• Provides register compatibility with the PCI 9054 for software migration
• Includes integrated PCI arbiter supporting seven external masters

Specialized Applications

• Motorola MPC 850/860 PowerQUICC based designs for datacom and telecom
• CompactPCI adapters in industrial, telecom, and networking applications
• Traditional PCI adapter cards requiring 32-bit, 66MHz operation
• I/O intensive embedded host designs such as network switches and routers

Specialized Procurement Notes

Verify component authenticity through manufacturer documentation or authorized channels. Confirm the specific suffix indicates lead-free compliance. Check for end-of-life status as distribution may be limited. Ensure environmental compliance matches project requirements before procurement.

Specialized Selection Notes

Select this component for designs requiring direct connectivity to Motorola PowerQUICC processors or generic 32-bit local buses. It is suitable for applications needing hot-swap support and high-performance data transfer rates up to 264 MB/sec. Consider backward compatibility with PCI 9054 if existing software drivers are utilized.

Specialized Part Context

This component belongs to the PLX Technology PCI 9056 series, which serves as a bridge between local bus masters and the PCI bus. It is part of a family that includes variants like the PCI 9054 and the 64-bit PCI 9656. The device is manufactured by Broadcom Limited, formerly PLX Technology.

Specialized Replacement Considerations

The PCI 9056 is register compatible with the PCI 9054. For designs requiring 64-bit PCI support, the PCI 9656 is a related product offering 32-bit local bus support.
