Architecture overview

The architecture of the CX9020 Embedded PC is described below.

The CX9020 Embedded PC is based on the ARMv7-A microarchitecture developed by Arm^®. The following CPU is used in the CX9020:

• i.MX535 Cortex^®-A8

Details for the CPU can be read at Arm^®. The memory is connected directly to the CPU. The embedded PC is available in one memory configuration: with 1 GB DDR3 RAM. The memory is not extendable. The CX9020 Embedded PC has two microSD card slots.

The CPU provides all required interfaces:

• 2x switched Ethernet RJ45 ports
• 4x USB 2.0
• DVI-D
• serial interface (CX9020-N03x)
• 1 EMI to FPGA for K-bus/E-bus and NOVRAM
• 2x microSD card slots

The USB, DVI, and LAN interfaces are standard interfaces. They can be used for operating devices that comply with the relevant standard. Only digital signals can be transmitted via the DVI-D interface.

The RJ45 interfaces are fed to an internal switch and no additional Ethernet switches are required.
