Single Chip UART IC 8 Channel PCI UART Interface XR17V358IB176-F

Product Specification

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).
