HIGH PERFORMANCE QUAD PCI-EXPRESS UART
GENERAL DESCRIPTION
The XR17V3541 (V354) is a single chip 4-channel PCI Express (PCIe) UART (Universal Asynchronous Receiver and Transmitter), optimized for higher performance and lower power. The V354 serves as a single lane PCIe bridge to 4 indepedent enhanced 16550 patible UARTs. The V354 is pliant to PCIe 2.0 Gen 1 (2.5GT/s). In addition to the UART channels, the V354 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 V354 has many enhanced Features such as the 256-bytes TX and RX...
