PCI9656-BA66BI

Specialized Overview

The PCI9656-BA66BI is a 64-bit, 66MHz PCI Bus Mastering I/O Accelerator designed for Motorola PowerQUICC and generic 32-bit local bus applications. It operates at a maximum clock frequency of 66 MHz with a data rate of 4224 Mb/s. The device supports a 64-bit PCI interface and a 32-bit local bus, achieving burst transfer speeds up to 528 MB/sec on the PCI bus and 264 MB/sec on the local bus. Powered by a 2.5 V core voltage, it utilizes a 272-ball PBGA package measuring 27 x 27 mm with a 1.27 mm pitch. Operating temperatures range from -40°C to +85°C.

Specialized Feature Summary

• Supports 64-bit, 66MHz PCI r2.2 operation with zero wait state bursts
• Features Data Pipe Architecture technology for high-speed I/O acceleration
• Includes PICMG 2.1 r2.0 Hot Swap Silicon capabilities
• Provides register compatibility with the PCI 9054 for software migration

Specialized Applications

• Motorola MPC 850/860 PowerQUICC designs
• CompactPCI adapters in industrial and telecom environments
• Generic 32-bit, 66MHz local bus designs using DSPs or FPGAs
• Embedded host designs requiring PCI bus configuration

Specialized Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status as indicated in current documentation. Check for end-of-life notifications or obsolescence warnings prior to procurement. Ensure packaging specifications match design requirements. Validate supply chain integrity to avoid counterfeit components.

Specialized Selection Notes

Select this component for systems requiring direct connectivity to Motorola PowerQUICC processors or generic 32-bit local buses. Consider its backward compatibility with PCI 9054 registers for legacy system upgrades. Evaluate the need for Hot Swap support if designing CompactPCI adapters. Assess power management requirements against its D3COLD PME generation capability.

Specialized Part Context

This part belongs to the PLX Technology PCI 9656 series, now under Broadcom. It serves as an advanced I/O accelerator bridging 32-bit local buses to 64-bit PCI architectures. The series includes variants like the PCI 9056 for different local bus configurations. It represents a transition point in PLX's I/O acceleration product line focusing on high-performance networking and telecom applications.

Specialized Replacement Considerations

The PCI 9056 offers similar functionality with support for 32-bit, 66MHz PCI and local bus operations. Designers should verify register compatibility and pinout differences when considering substitution. Software migration efforts may vary depending on specific feature utilization.
