Architekture overview

The Embedded PCs of the CX50x0 family all have the same architecture, which is described below.

The CX50x0 Embedded PCs are based on the Intel Atom microarchitecture, which was developed by Intel. The CPUs used in the CX50x0 family are:

• Intel^®Atom^TM Z510 (Singlecore)
• Intel^®Atom^TM Z530 (Singlecore)

For details on the CPUs please refer to Intel. The graphics controller is located in the Intel^® SCH US15W chipset. The two EPC variants therefore have the Intel^® GMA 500 as graphics core. The memory is also directly connected to the chipset. The EPC is available in two memory configurations: with 512 MB and optionally with 1 GB DDR2 RAM.

In all CX50x0 EPCs the Intel^® SCH US15W chipset is used. This chip provides all required interfaces:

• 4x USB 2.0 (interfaces)
• DVI-D interface
• 1 PCIe lane for each of the two Intel^® 82574L Gigabit Ethernet controllers
• LPC interface for Winbond W83627HG controller for serial interface (CX50x0-N03x)
• 1 PCIe for FPGA for K-/E-bus
• 1 IDE for Compact Flash card interface

The interfaces (USB, DVI, and LAN ports) are standard interfaces. They can be used for operating devices that comply with the standard. Intel^® 82574L Gigabit Ethernet controllers are used as network controllers. There are two independent ports, which are both gigabit-capable.

Details of the individual system interfaces are described in separate sections.
