Single-chip 8-channel PCI UART Interface Integrated Circuit 256Byte FIFO XR17V358IB176-F

GENERAL DESCRIPTION
The XR17V3581 is a single chip 8-channel PCI
Express (PCIe) UART (Universal Asynchronous
Receiver and Transmitter), optimized for higher
performance and lower power. The XR17V358
serves as a single lane PCIe bridge to 8 independent
enhanced 16550 compatible UARTs. The XR17V358
is compliant to PCIe 2.0 Gen 1 (2.5 GT/s).
In addition to the UART channels, the XR17V358 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 XR17V358 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 XR17V358 is available in a 176-pin
FPBGA package (13 x 13 mm).
