CM50 - Rugged COM Express Module with Intel Atom Processor E3900 Series

Truly Rugged COM Express Module

The CM50 is an ultra-rugged COM Express module with Type 10 Pin-Out for rolling stock, public transportation and industry applications. It is operable in an extended temperature range of -40 °C up to +85 °C (Tcase). The use of soldered components makes the board resistant to shock and vibration.

Versions for Extremely Harsh Environments

For applications that need reliable operation even under the harshest environmental conditions, a specially hardened version is available - the CM50C. CM50C modules are embedded in a closed aluminum frame that ensures optimum EMC protection, efficient conduction cooling and extended resistance to vibration and shock. Direct air cooling is possible by placing a heat sink on the cover. The innovative mechanical design around the COM.0 electronics makes it an ultra-rugged module.

Scalable Low Power Processor

The Intel E3900 CPU series provides a scalable performance up to 4 cores and integrated quality graphics. Intel VT-x virtualization support allows to run multiple applications on a single hardware platform, saving costs. Due to the low power dissipation (depending on the CPU), no active cooling is necessary and very small designs are feasible.

Safety, Security and Connectivity

The board management controller has supervision functions (onboard voltages, temperature etc.) that make the board suitable for safety-related applications. The Trusted Platform Module supports features like secure/measured booting and fast cryptographic execution. The CM50 comes with a large variety of interfaces, including, e.g., Digital Display Interfaces, HD Audio, PCI Express and Gigabit Ethernet. This enables implementing many functions on a very small form factor.
