MEN: SIL 2 certificate for QorIQ COM module
The Rugged COM Express module CB30C has been developed according to railway standards EN 50128 (software) and EN 50129 (hardware) and has now received the SIL 2 certification from TÜV SÜD. Due to its robust design, it is particularly suitable for safety-critical applications, e.g., in rail or bus transport, but also in demanding industrial applications.
The CB30C complies with the requirements of the EN 50218 and EN 50129 standards for software, system and hardware development in railways. Within these standards, the RCE module is now certified to safety integrity level SIL 2 and comes with the appropriate certification package, which includes the safety case and the certification report from TÜV SÜD. The package will simplify the certification process of the final system considerably and will consequently shorten the project time.
To achieve the SIL 2 level, the board is monitored by a specially developed CPLD (Complex Programmable Logic Device) supervisor. In case the defined operating conditions like the supply voltage or temperature reach the critical limits, the safe supervisor interrupts the power to the subsystem, ensuring all external communications are stopped. With the onboard event logger error states can be read out and analyzed.
According to the Rugged COM Express standard, the CB30C is embedded in a solid aluminum frame protecting the electronics against environmental impacts like humidity, dust or electromagnetic radiation and additionally supporting operation in the extended temperature range of -40 to +85°C via conduction cooling. And, of course the complete design is compliant to the EN 50155 railway standard.
Based on the QorIQ single core P1013 or dual core P1022 processor from NXP, the CB30C running at up to 1 GHz has an excellent performance per watt. With its focus on safe design, the CB30C still offers ample I/O functionality, including up to three Gigabit Ethernet and PCI Express interfaces, two SATA channels, up to four USB ports and UARTs. The CB30C complies with the COM Express Basic form factor and type 6 pin-out. A COM Express version without the aluminum frame is also on offer.
