OXPCIe200, PCI Express multi-port bridge
Part of the Expresso family of high performance PCI
Express devices, the OXPCIe200 is a single chip
multi-port bridge with a rich set of connectivity ports
and advanced system management to maximize data
throughput while substantially reducing CPU and
system loading.
ƒ General Features
o Dual USB 2.0 host ports or USB 2.0 host port &
SPI/SRAM port, both with UART port configuration
o PCIe x1 end-point
- Integrated 2.5 GT/s SerDes
o 9 x 9mm2, 156-pin TAPP package
o Typical Power: 300 mWatts
A fully integrated, single lane PCI Express endpoint
controller and SerDes enables host system access to
USB2.0 host, SPI and SRAM ports, a PLX
Technology’s ultra high performance Oxford 950
UART, plus user defined GPIOs/PWMs. The device
is configurable as dual USB host ports or one USB2.0
host port & one SPI or SRAM port providing a high
throughput communication path from a PCI Express
host system to a slave processor or peripherals.

Outstanding Performance
Development Support
The OXPCIe200 achieves ultra high performance by
combining the class leading connectivity interface
technology, with advanced MSI interrupt handling
on-board memory and bus master DMA for maximum
throughput, minimum CPU overhead and optimal
system performance.
With a compact footprint, comprehensive power
management and industrial temperature range as
standard, the OXPCIe200 is perfect for power and
temperature sensitive ExpressCard and miniCard
designs and is the perfect choice for high performance
To support these advanced connectivity options, the
OXPCIe200 uses operating system native USB
drivers and dedicated PLX device drivers that are
quality assured, exhaustively tested and WHQL
approved; saving development time and providing
peace of mind.
Design and evaluation of the OXPCIe200 couldn’t be
easier with this comprehensive reference design kit
(RDK). The RDK includes everything you need for
PC installation and evaluation including Hardware,
Oxide Development Tools and software device
drivers. Simply plug the half length PCI Express or
ExpressCard evaluation board into any PCI Express
or ExpressCard slot, install the software and its ready
to go.
Changing the dynamics of device customization,
Oxide development tools enable customization of the
OXPCIe200 in minutes. No more complex, time
consuming, error prone manual editing of
programming files and driver source code; Oxide’s
intuitive graphical user interface provides simple
‘point and click’ feature selection and text box entry
for fast, error free customization with minimal
software expertise as well as instant access to up to
date documentation, software and reference designs.
