OXPCIe200, PCI Express multi-port bridge
Highlights
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.
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.
Key Features

- Integrated USB2.0 full speed Phy
- Master or slave mode SPI or SRAM port
- Data rates of 60Mbps (SPI) & 25MB/s (SRAM)
- 8KB slave memory with direct access or 16 channel
FIFO modes
- PLX’s Oxford 950 UART
- DMA/bus mastering of both UARTs
- Asynchronous baud rates up to 15 Mbps
- 128-byte deep transmit/receive FIFO
- 9, 8, 7, 6 & 5-bit data framing
- Automated in & out-of-band flow control
- Advanced FIFO fill management
