XR17V352
HIGH PERFORMANCE DUAL PCI EXPRESS UART
APRIL 2012
REV. 1.0.3
GENERAL DESCRIPTION
The XR17V3521 (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. The V352 is available in a 113-pin FPBGA
package (9 x 9 mm).
