PCIe x1 XR17V352 2-port RS422/485 Serial Adapter Card with 16550 UART
$65.00
- Product Code: PX1-2S-422
- Availability: In Stock
The XR17V352 (V352) is a single chip 2-channel PCI Express (PCIe) UART (Universal Asynchronous Receiver and Transmitter), optimized for higher performance and lower power. The V352 serves as a single lane PCIe bridge to 2 indepedent enhanced 16550 compatible UARTs. The V352 is compliant to PCIe 2.0 Gen 1 (2.5GT/s).
In addition to the UART channels, the V352 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 V352 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.
