XR17V354
XR17V354 is HIGH PERFORMANCE QUAD PCI-EXPRESS UART manufactured by MaxLinear.
DESCRIPTION
The XR17V3541 is a single chip 4-channel PCI Express (PCIe) UART (Universal Asynchronous Receiver and Transmitter), optimized for higher performance and lower power. The XR17V354 serves as a single lane PCIe bridge to 4 independent enhanced 16550 patible UARTs. The XR17V354 is pliant to PCIe 2.0 Gen 1 (2.5 GT/s).
In addition to the UART channels, the XR17V354 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 XR17V354 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 31.25 Mbps. The XR17V354 is available in a 176-pin FPBGA package (13...
