www.DataSheet4U.com xr NOVEMBER 2005 XR17V258 66MHZ PCI BUS OCTAL UART WITH POWER MANAGEMENT SUPPORT REV. 1.0.0 GENERAL DESCRIPTION The XR17V2581 (V258) is a single chip 8-channel 66MHz PCI (Peripheral Component Interconnect) UART (Universal Asynchronous Receiver and Transmitter) solution, optimized for higher performance and lower power. The V258 device with its fifth generation register set is designed to meet the high bandwidth and power management requirements for multi-serial communication ports for system administration and management. The 32-bit 66MHz PCI interface is compliant with PCI 3.0 and PCI power management revision 1.1 specifications. The device provides an upgrade path for Exar’s 33MHz 5V and Universal PCI UART family of products in a 144-pin LQFP package.
