Targeted datacom and telecom applications include high-speed routers/switches, Frame Relay adapters, WAN/LAN controllers, and modem cards. The PCI 9656 simplifies these designs by providing an enhanced direct-connect interface to the PowerQUICC processor family. The flexible 3.3V, 5V tolerant I/O buffers, combined with local bus operation up to 66MHz, are ideally suited for current and future PowerQUICC processors. The PCI 9656 supports the PowerQUICC IDMA channels for data transfer between the integrated PowerQUICC communication channels and PCI. In addition, the PCI 9656 exploits PLX’s leading edge Data Pipe Architecture technology, allowing unlimited bursts, as illustrated in the figure below. The PCI 9656, with its internal PCI arbiter, reset signal direction control, and Type 0/1 PCI configuration support, is ideal for CompactPCI system cards. Generic 32-bit, 66MHz Local Bus Designs The PCI 9656 also supports two generic de facto standard bus interfaces, one with demultiplexed and the other with multiplexed address and data busses. Because of their high speed and relative simplicity, these C and J bus modes have been embraced by designers of a wide variety of devices including processors, DSPs, memories, custom ASICs, and FPGAs. PCI Adapters The PCI 9656 is also designed for traditional PCI adapter card applications requiring 64-bit, 66MHz PCI operation and bandwidth. Specific applications are high performance communications, networking, disk control, RAID, and data encryption adapters. Today, Power Management and Green PCs are major initiatives in traditional PCI applications. The PCI 9656 supports PCI power management, including generation of PME in the D3COLD state. This is a requirement for modem and communications adapters in Windows desktop and server systems.. CompactPCI Adapters The PCI 9656 is the ideal choice for CompactPCI adapters in industrial, telecom, and networking applications. These applications include WAN/LAN controllers, modem cards, Frame Relay adapters, and telephony cards for telecom switches and remote-access systems. The PCI 9656 has integrated key features to enable live insertion and extraction of CompactPCI Hot Swap adapters. The PCI 9656 is PICMG 2.1 r2.0 Hot Swap Silicon, supporting Programming Interface 0 (PI=0). It includes Bias Voltage and Early Power support for ease of Hot Swap board design. Further, the PCI 9656 includes an option to suppress PCI target retries during chip initialization, providing the optimal behavior for live insertion in Hot Swap systems. For PowerQUICC IDMA operation, the PCI 9656 transfers data to the PCI bus under the control of the IDMA handshake protocol using Direct Master transfers. 1 Simultaneously, the two PCI 9656 DMA channels run as masters on both buses to perform bi-directional data transfers between the local bus and the PCI bus. 2 COM 1 COM 2 COM N This is a prime example of how the PCI 9656 gives PowerQUICC designers greater flexibility in implementing multiple simultaneous I/O transfers. MPC860 SDRAM Flash J2 2 IDMA 1 DMA 0 32-bit, 66MHz Local Bus EEPROM PCI 9656 2 DMA 1 64-bit, 66MHz PCI Bus J1 PCI 9656 PowerQUICC CompactPCI Adapter Embedded Host Designs I/O intensive embedded host designs are another major application of the PCI 9656. These applications include network switches/routers, printer engines, set-top boxes, CompactPCI system cards, and industrial equipment. While the support requirements of these embedded host designs share many similarities with peripheral card designs, there are three significant differences: ■ A host must configure the PCI bus. The PCI 9656 supports PCI Type 0 and Type 1 configuration cycles. ■ A host must provide a PCI bus arbiter. The PCI 9656 arbiter supports seven external PCI masters, enough for a CompactPCI backplane with 7 peripheral slots. ■ For hosts, the directions of reset and interrupt signals reverse. The PCI 9656 includes a strapping option to accomplish this. In one setting, the directions are appropriate for a peripheral. In the other, they are appropriate for a host.
