Certification for safety-critical railway applications with C167 MCU

July 11, 2014 // By Graham Prophet
Embedded Office, a specialist company for embedded systems that specialises in safety-critical applications, has extended the range of its Cert-Kits and is now offering a component for the µC/OS-II OS, pre-certified on the 16-bit microcontroller C167 from Infineon.

The offering supports manufacturers of safety-critical systems in standard-compliant development according to DIN EN50128 SIL-4. The C167 is a proven microcontroller, typically used in the automotive sector, in medical engineering and in industry, for example in railway applications.

By using the real-time kernel µC/OS-II as a pre-certified component, this product facilitates the development of safety-critical applications and considerably reduces the certification process. The Cert-Kit comprises all the elements required for creating an executable application. These include the certified source code, various software manuals such as safety, target integration, user, reference and system manual. The Cert-Kit also contains validation software (including reference board support package) and the TÜV certificate pertaining to the type approval of the pre-certified software component. Upon request, the test environment can also be made available to customers. The Cert-Kit provides flexibility so Embedded Office can adapt the certification of µC/OS-II to other CPUs and development environments with minimum effort. In addition to the standard EN50128, it is also suitable for the development of safety-critical devices according to the standards IEC62304 (med ical sector) and IEC61508 (industrial applications).

µC/OS-II is a portable, ROM-capable, scalable, pre-emptive, deterministic real-time kernel for microprocessors, microcontrollers and DSPs. It is used in many different industries. The real-time kernel is particularly popular in the safety-critical environment, because the source code is written in a comprehensible manner and is well documented. µC/OS-II has proven itself in a wide variety of applications within safety-critical areas. The real-time kernel provides a wide range of functions: semaphores, mutual-exclusion semaphores, event flags, message mailboxes, message queues, memory management, task management and timer management.
