Architekture overview
The Embedded PCs of the CX20x0 family all have the same architecture. The architecture is described below.
The CX20x0 Embedded PCs are based on the Sandy Bridge microarchitecture developed by Intel. The following CPUs are used:
- Intel®Celeron® 827E (Singlecore),
- Intel®CORETM i7 2610UE (Dualcore),
- and Intel®CoreTM i7 2715QE (Quadcore).
In addition to the arithmetic unit, the CPU also contains the memory controller and the graphics controller. The single-core processor uses the Intel® HD has as graphics core. The two CoreTM i7 CPUs (dual or quad core) feature an Intel® HD graphics 3000 core. This offers a somewhat higher performance than the Intel® HD graphics core, and the quad core offers a higher clock speed. For details on the CPUs please refer to Intel. The memory is connected directly to the memory controller. The Embedded PCs are available in two memory configurations: 2GB or 4GB DDR3 RAM. The memory is not expandable and must be ordered ex factory.
All CX20x0 Embedded PCs use the Mobile Intel® QM67 Express chipset (Intel® BD82QM67 PCH). This chip provides all required interfaces:
- 4 x USB 2.0
- 1x USB 2.0 internal (power supply unit control button / display).
- DVI-I and DVI-D interface (second interface optional CX20x0-N010).
- 1 PCIe lane for each of the two Intel® 82574L Gigabit Ethernet controllers
- LPC interface for super I/O controller for serial interface (CX20x0-N03x).
- 4 PCIe lanes via the multi-pin connection (left).
- 1 PCIe to FPGA for K-/E-bus and NOVRAM.
- 2x SATA internal via the multi-pole connection (right).
- 2x USB internal via the multi-pin connection (right).
The interfaces (USB, DVI, and LAN) are standard interfaces. Devices that meet the corresponding standard can be connected to and operated at these interfaces. A VGA monitor can be connected to the DVI-I interface with an adapter.
Intel® 82574L Gigabit Ethernet controllers are used as network controllers. There are two independent LAN interfaces. Both LAN interfaces are gigabit-capable and support jumbo frames.
