Profile: Integrated Device Technology, Inc. is an international designer, manufacturer and marketer of microprocessors and integrated circuits. Our product line includes analog & USB switches, audio solutions, digital logic, memory interface and processor products. Our analog & USB switches & devices are used to minimize redundant circuitry and board space. The wide range of analog, USB and hybrid switch portfolios offered by IDT are well suited for portable and handheld applications. The IDT PowerSpan™ II is a multi-port PCI bus switch that bridges PCI to the PowerQUICC™ II (MPC8260), MPC7xx, PowerPC® 7xx, and the Wintegra WinPath™ processors. PowerSpan II is available in either a single PCI or dual PCI variant. The device defines a new level of PCI bus switch flexibility. The device has a switched PCI architecture which maximizes transfer concurrency, and improves the efficiency and burst performance on the PCI and processor buses. The single PCI PowerSpan II is a two-port device that has a PCI interface and a PowerPC bus interface. The dual PCI variant is a three-port device that has two PCI interfaces and a PowerPC bus interface. The PowerSpan II in conjunction with the PowerPro PowerPC memory controller provides a 100-MHz PowerPC interconnect solution. This flexible offering allows designers to leverage the PowerSpan and PowerPro devices across many different system architectures with a common investment in software. The IDT lineup of system monitor devices increase the reliability of complicated platforms. The current devices provide a baseline functionality, and the design methodology allows for quick and simple modifications to supply optimum solutions.
