MEN Mikro CM50C Rugged COM Express module

CM50C is a low-power and space-saving Rugged COM Express module that was developed around the Intel Atom E3900 series of processors. Due to the low power consumption, the virtualisation support of the processor and the safe board management controller, the robust module is a multifaceted solution for individual designs in harsh environments and safety-critical applications.

The unit is an ultrarugged COM Express Mini module for rolling stock, public transportation and industry applications. It is compatible with COM Express Type 10 Pin-Out and conforms to the VITA 59 standard, which specifies the mechanics to ensure operation in harsh environmental conditions.

Based on the Intel E3900 CPU series with a low power dissipation of 7–16 W, the product provides scalable performance with up to four cores and integrated quality graphics, as well as Intel VT-x virtualisation support. This allows it to run multiple applications on a single hardware platform, saving physical hardware.

The board management controller is designed to reduce downtime and is certifiable up to SIL 2. With the Trusted Platform Module and secure/measured booting features, fast cryptographic execution is supported. The product comes with a large variety of interfaces, including, eg, Digital Display Interfaces, HD Audio, PCI Express and Gigabit Ethernet.

In accordance with the Rugged COM Express standard, the module is embedded in a solid aluminium frame that protects the electronics from environmental influences such as humidity, dust, vibrations or EMC radiation and also enables operation in the extended temperature range from -40 to +85°C via conduction cooling. The processor’s long-term availability of 15 years ensures an extended product life for a wide range of applications.

For less demanding applications, a standard COM Express variant without frame is also available.
