The CP11 provides a unique feature set, including up to 4 GB of DDR2 SDRAM (200 MHz) with enhanced ECC, four independent on-board PCI buses, system host and peripheral mode support for the CPCI backplane, two PMC interfaces (64-bit/133 MHz and 32-bit/33 MHz). Instead of the PMC1, a PCI Express™ based XMC interface is available on request. A high level of functional integration (two Gigabit Ethernet, one Fast Ethernet, two serial interfaces (RS-232 or RS-422/485), USB 2.0, integrated HDD or Flash drive) gives users the freedom to use the PMC interfaces for their application specific I/O. The VGA/DVI interface is supported through a high performance 2D/3D ATI® video controller capable of driving two displays in parallel.
