The ARM9-CPU of the ECUcore-9G20 runs at 400 MHz and features high performance at low power consumption. Linux as operating system allows for simultaneous execution of different user applications. Due to the freely programmable on-board FPGA, it is possible to realize basic digital in- and outputs as well as highly complex peripheral units. The basic version of the FPGA already includes powerful counter and PWM units. Additionally, the board features 3 ADC channels. Both, the VHDL sources of the FPGA and the source code of the I/O driver, are available with our Driver Development Kit (DDK). This makes a flexible implementation of own I/O connections possible.

A comprehensive CANopen library is available for the ECUcore-9G20. Amongst others, it contains a CiA 302-conform CANopen Manager. It supports automatic node configuration and enables flexible expandability of the module via CANopen units and easy plug & play.

In addition to the Ethernet and CAN interface, the ECUcore-9G20 features two USB 2.0 Full Speed host ports, one USB device port and 4 UART ports. Due to the numerous communication interfaces, the module is well-suitable as central unit in distributed automation systems and as communication gateway.

Linux as a mainstream CPU supports the ARM9 architecture and hence ensures the availability of actual kernel versions for the module. Moreover, for ARM processors there exist various ports of current standard software and the industry-proven Linux Realtime extension Xenomai.

Thanks to an extended firmware, the same hardware module is also available as Linux-based Hard PLC for the usage in OEM applications. The so called PLCcore-9G20 supports C/C++ and other textual and graphical programming according to IEC 61131-3.
