PCI9656 pdf datasheet

Maximum PCI Bandwidth for Your 32-bit Local Bus Applications
The PCI 9656 offers flexible connectivity and high performance I/O acceleration features
to enable leading edge PCI, CompactPCI, and embedded host designs.
?
Motorola MPC 850/860 PowerQUICC Designs
The PCI 9656 is the perfect match for the industry leading 32-bit communication proces-
sor, the Motorola MPC 850/860 PowerQUICC. The PCI 9656 provides a direct connection
to PowerQUICC devices, enabling high-speed 64-bit, 66MHz PCI performance with its
Data Pipe Architecture? technology. 
Generic 32-bit, 66MHz Local Bus Designs
The PCI 9656 provides direct connection to two generic industry standard interconnect
buses. Designers use these 32-bit, 66MHz buses for a myriad of high-speed devices rang-
ing from processors, to DSPs, to memories, to custom ASICs and FPGAs.
The PCI 9656 Data Pipe Architecture technology enables high-speed, 64-bit, 66MHz PCI
I/O with those devices.

64-bit, 66MHz PCI Operation
As PCI evolves to meet the ever increasing I/O demands of leading edge systems, PLX
continues to provide leading edge, high performance PCI I/O acceleration solutions. Based
on the architecture of the industry-leading PCI 9054, the PCI 9656 offers a variety of
enhancements for the needs of today's telecom, networking, and I/O adapter designs:
64-bit, 66MHz PCI operation
32-bit, 66MHz local bus operation
Dynamic DMA descriptor ring management with Valid bit semaphore control
PICMG 2.1 r2.0 Hot Swap Silicon, including Bias Voltage, Early Power, 64-bit
Initialization, and Intially Not Responding Support
PCI Power Management r1.1 D3 Power Management Event (PME) generation
COLD
PCI arbiter supporting 7 external masters
Reset and interrupt pins configurable for embedded host applications
JTAG boundary scan
The PCI 9656 is register compatible with the PCI 9054, enabling easy software migration.
