Features & Applications

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.

The V258 consists of eight independent UART channels, each with set of configuration and enhanced registers, 64 bytes of Transmit (TX) and Receive (RX) FIFOs, and a fractional Baud Rate Generator (BRG). A global interrupt source register provides a complete interrupt status indication for all 8-channels to speed up interrupt parsing. The V258 device operates at 33/66MHz and features fully programmable TX and RX FIFO level triggers, automatic hardware and software flow control, and automatic RS-485 half duplex direction control output for software and hardware design simplification.
