PCI 9080 I2O Compatible PCI Bus Master I/O Accelerator Chip Features s PCI Version 2.1 compliant Bus Master interface chip for adapters and embedded systems local bus supports nonmultiplexed 32-bit address/data, multiplexed 32- or 16-bit, and accesses of 32-, 16-, or 8-bit local bus devices s Programmable sI 2O compatible messaging unit s 3.3 or 5 volt PCI signaling, 5 volt core, low-power CMOS in 208-pin PQFP s Two independent programmable DMA channels for local bus memory to/from PCI host bus data transfers programmable FIFOs for zero wait state burst operation to/from local data transfers up to 133MB/sec bus runs asynchronously to the PCI bus 32-bit mailbox and two 32-bit doorbell registers Big Endian/Little Endian conversion compatibility with PCI 9060, 9060ES, 9060SD s Eight s PCI s Local Flexible Connection to the PCI Bus For add-in card and embedded system designers and integrators alike, the mission is clear: reduce the time to integrate new technology and time to market. Achieving this task requires the latest in I/O technology. PLX Technology, Inc. is committed to providing complete and proven PCI solutions with our PCI 9080 Bus Master I/O Accelerator interface chip. The PLX® PCI 9080 provides a compact, high performance PCI bus master interface with a programmable local bus. Integrating the latest in I/O technology, the PCI 9080 contains an Intelligent I/O (I2O) messaging unit in hardware that allows high performance and compatible software implementations of the I2O bus protocol specification. The highly flexible local bus solution can be configured to directly connect a wide variety of processors, controllers and memory subsystems. Combined with the PCI 9080RDK reference design kits, PCI SDK and I2O software development kits available from PLX, the design-in process is simple and painless with little or no glue logic. Customers are using the PCI 9080 with IBM PowerPC 40x, Motorola MPC850/860, Intel i960C/J/H, Hitachi Super H, MIPS R 3000/4000/5000, NEC V830/831, ARM, Motorola 68XXX, and others. Thoroughly tested and proven, PLX products have become the gold standard of the industry. Leading the way in PCI design, the PCI 9080 provides two intelligent DMA channels with scatter/gather, programmable burst modes, and asynchronous bus clocks to provide the best PCI throughput available. The versatility of the PCI 9080 also allows for a local processor to configure other PCI devices in the system. While the PCI 9080 is capable of keeping up with the most demanding of applications and the latest in technology, upward compatibility with existing PLX PCI I/O accelerators is maintained. The 9080 continues the PLX tradition of providing the highest performance and fully compatible PCI interface solutions. s Eight s Performs s Upward TECHNOLOGY ® Technical Speci cations Package PCI compliance I2O messaging unit Interface protocol PCI signaling Local bus speed Big/Little Endian conversion PCI Bus Speed PCI host capability Mailbox registers Doorbell registers Unaligned DMA transfer support Programmable local bus modes Mode C Mode J Mode S Serial EEPROM interface 208-pin PQFP PCI local bus specification, v. 2. 1 PCI extension of the Ispeci cation v.1.5 2O Direct bus master 3. 3v or 5v 0-40MHz Dynamic switching for direct slave, direct master, DMA, and the internal register accesses on the local side 33MHz max Type 0 or Type 1 PCI con guration cycles in direct master mode Eight 32-bit, accessed from PCI or local bus Two 32-bit, one from PCI to local bus, one from local bus to PCI bus From any byte boundary Selected through mode pins 32-bit address/32-bit data, non multiplexed 32-bit address/32-bit data, multiplexed 32-bit address/16-bit data, non multiplexed Supported PCI 9080 Internal Block Diagram Internal Registers PCI Con g Local Con g Run-Time DMA I2O Messaging PCI Bus State Machines PCI Initiator (For Direct Master Xfers) EEPROM Initialization FIFOs Dir.
