XR17V358

High Performance Octal PCI Express UART

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 independent enhanced 16550 compatible UARTs. The V358 is compliant 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 FIFOs, programmable Fractional Baud Rate Generator, Automatic Hardware or Software Flow Control, Auto RS-485 Half-Duplex Direction Control, programmable TX and RX FIFO Trigger Levels, TX and RX FIFO Level Counters, infrared mode, and data rates up to 25Mbps. The V358 is available in a 176-pin fpBGA package (13 x 13 mm).

NOTE¹: Covered by U.S. Patents #5,649,122, #6,754,839, #6,865,626 and #6,947,999
