DESCRIPTION

· The PCI 9656 is a 64-bit, 66MHz PCI Bus Mastering I/O Accelerator designed for Motorola PowerQUICC™ and generic 32-bit, 66MHz Local Bus applications.

· It provides high-performance I/O acceleration for PCI, CompactPCI, and embedded host designs.

· The device features Data Pipe Architecture™ technology for high-speed PCI performance.

FEATURES

· 64-bit, 66MHz PCI operation and 32-bit, 66MHz local bus operation.

· Dynamic DMA descriptor ring management with Valid bit semaphore control.

· PICMG 2.1 r2.0 Hot Swap Silicon support, including Bias Voltage, Early Power, 64-bit Initialization, and Initially Not Responding.

· PCI Power Management r1.1 D3 COLDPower Management Event (PME) generation.

· PCI arbiter supporting 7 external masters.

· Reset and interrupt pins configurable for embedded host applications.

· JTAG boundary scan.

APPLICATIONS

· Ideal for Motorola MPC 850/860 PowerQUICC designs.

· Suitable for generic 32-bit, 66MHz local bus designs, connecting to processors, DSPs, memories, ASICs, and FPGAs.

· Used in telecom, networking, and I/O adapter designs requiring high-speed PCI I/O.
