64-bit, 66MHz PCI Bus Mastering I/O Accelerator for Motorola
PowerQUICC
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
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.
