IOP 480 PLX Technology Controller Board

The Broadcom / PLX Technology IOP 480 Controller Board feature a distributed processing architecture, a high speed PCI system bus, a high performance, low cost processor, efficient memory management, flexible I/O device interface, high performance burst mode data transfers, intelligent message passing support, and efficient I/O transaction management. To meet these requirements, the new IOP 480 integrates a 66 MHz, PowerPC core and highly flexible memory controller with PLX's industry leading advanced Data Pipe ArchitectureTM PCI controller including dual DMA channels, programmable PCI Initiator and Target data transfer modes and PCI messaging functions. The IOP 480 is available in space saving PQFP or PBGA packages with power management and CompactPCI Hot Swap Friendly support.

The IOP 480 provides a highly flexible local bus with 8-, 16-, or 32-bit operation, at speeds up to 66 MHz, and offers Fly-By DMA with burst transfers between local memory and I/O devices. To maximize flexibility in design, the 3.3V IOP 480 offers 5V tolerant signaling on both the PCI and Local bus, complies with PCI v2.2, and supports the performance enhancements in I2O v2.0. With support for both type 0 and 1 configuration cycles, and arbiters for both the PCI and Local bus, the IOP 480 is ideal for embedded host as well as adapter card designs.
