HIGH PERFORMANCE OCTAL PCI EXPRESS UART
GENERAL DESCRIPTION
The XR17V3581 (V358) is a single chip 8-channel PCI Express (PCIe) UART (Universal Asynchronous Receiver and Transmitter), optimized for higher performance and lower power. The V358 serves as a single lane PCIe bridge to 8 indepedent enhanced 16550 patible UARTs. The V358 is pliant to PCIe 2.0 Gen 1 (2.5GT/s). In addition to the UART channels, the V358 has 16 multi-purpose I/Os (MPIOs), a 16-bit general purpose counter/timer and a global interrupt status register to optimize interrupt servicing. Each UART of the V358 has many enhanced Features such as the 256-bytes TX and RX...
