XR17V258
66MHZ PCI BUS OCTAL UART WITH POWER MANAGEMENT SUPPORT
AUGUST 2010
REV. 1.0.2
GENERAL DESCRIPTION
The XR17V2581 (V258) is a single chip 8-channel
66MHz PCI (Peripheral Component Interconnect)
UART
(Universal
Asynchronous
Receiver and
Transmitter)
solution,
optimized
for
higher
performance and lower power. The V258 device with
its fifth generation register set is designed to meet the
high
bandwidth
and
power
management
requirements for multi-serial communication ports for
system administration and management. The 32-bit
66MHz PCI interface is compliant with PCI 3.0 and
PCI power management revision 1.1 specifications.
The device provides an upgrade path for Exar’s
33MHz 5V and Universal PCI UART family of
products in a 144-pin LQFP package.
The V258 consists of eight independent UART
channels, each with set of configuration and
enhanced registers, 64 bytes of Transmit (TX) and
Receive (RX) FIFOs, and a fractional Baud Rate
Generator (BRG). A global interrupt source register
provides a complete interrupt status indication for all
8-channels to speed up interrupt parsing. The V258
device operates at 33/66MHz and features fully
programmable TX and RX FIFO level triggers,
automatic hardware and software flow control, and
automatic RS-485 half duplex direction control output
for software and hardware design simplification.
