MEN Mikro CB30C - Rugged COM Express (VITA 59 RCE) Safe Railway Computer

Up to dual core 1GHz CPU, 1 or 2GB soldered DDR3 Memory, eMMC flash storage onboard


The CB30C safe CPU board is a Rugged COM Express® module for use in safety-related applications, e.g., for rolling-stock train control systems or industrial applications. It is based on a Freescale™ QorIQ™ single-core P1013 or dual-core P1022 processor, running at up to 1 GHz and providing excellent performance per watt. It is hardware-supervised by a dedicated safe supervisor to meet EN 50129 SIL 2 level requirements. The technical assessment report from TÜV SÜD, included in the certification package, will greatly simplify certification at system level.

Functional Safety Architecture: Fail-Safe

The CB30C is a single-processor board with a reactive fail-silent design. The functional safety architecture is based on monitoring all safe CPU subsystem
environmental conditions such as voltages and temperature. If safe operation of the CPU subsystem cannot be guaranteed, the safe supervisor (SUPV) removes the power of the subsystem, ensuring all external communications are stopped. The SUPV also ensures it is only possible to exit the safe
state in a controlled manner. If an overvoltage is detected the CB30C is placed in a non-recoverable disabled state and needs to be shipped to MEN for inspection before possibly returning to the field.

An onboard event logger helps to analyze errors while reducing software overhead.

Rugged COM Design for Harsh Environments

The computer-on-module comes in a robust aluminum cooling frame and cover that shields the COM against EMC and provides a cooling interface for integration in fanless systems. With all components soldered, its small form factor and low power consumption, the board is ideal for embedded applications in severe environments. Its full EN 50155 compliance up to Tx gives it a focus on rolling-stock applications. 

Solid Connectivity and I/O

With its focus on safe design, the CB30C still offers ample I/O functionality, including two or three Gigabit Ethernet and PCI Express® interfaces, two SATA channels, up to four USB 2.0 ports, UARTs and general-purpose I/O. DVI or LVDS can be implemented for graphics functions. Up to 2 GB DDR3 SDRAM with ECC support and a soldered eMMC storage device round out the CPU.

Standardized VITA 59, COM Express® based

Being a VITA 59 standard computer-on-module, the CB30C complies with the COM Express® Basic form factor and type 6 pin-out. A COM.0 COM Express® version is also on offer. For evaluation and development purposes a microATX carrier board, the XC15, is available.
