Product overview
2.5 Architecture overview
The architecture of the CX9020 Embedded PC is described below.
The CX9020 Embedded PC is based on the ARMv7-A microarchitecture, which was developed by ARM
®
.
The following CPU is used in the CX9020:
• i.MX535 Cortex
TM
-A8
For details on the CPUs please refer to ARM. The memory is connected directly to the CPU. The Embedded
PC is available in one memory configuration: with 1GB DDR3 RAM. The memory is not expandable. The
CX9020 Embedded PC has two MicroSD card slots.
The CPU provides all required interfaces:
• 2x switched Ethernet-RJ45
• 4x USB 2.0
• DVI-D
• Serial interface (CX20x0-N03x)
• 1 EMI for FPGA for K-/E-Bus and NOV-RAM
• 2x MicroSD card slots
The interfaces USB, DVI, and LAN ports are standard interfaces. They can be used for operating devices
that comply with the standard. Only digital signals can be transmitted over the DVI-D interface.
The RJ45 interfaces are connected to an internal switch, without the need for additional Ethernet switches.
Details of the individual system interfaces are described in separate sections.
