JULY 2018
REV. 1.0.6
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.
