Rugged COM Express Type 10 Module Sports Intel Apollo Lake-I

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

The CM50C is a COM Express Mini module for rolling stock, public transportation and industry applications. It is compatible to COM Express Type 10 Pin-Out and conforms to the VITA 59 standard which specifies the mechanics to ensure reliable operation in harsh environmental conditions. In accordance with the Rugged COM Express standard, the CM50C is embedded in a solid aluminum 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.

Based on the Intel E3900 CPU series with a low power dissipation of 7 W to 16 W, the CM50C provides a scalable performance up to 4 cores and integrated quality graphics. It also offers Intel VT-x virtualization support. This allows to run multiple applications on a single hardware platform, saving physical hardware and costs.

The board management controller provides enhanced reliability, reduced downtime and is certifiable up to SIL 2. With the Trusted Platform Module and the secure/ measured booting features fast cryptographic execution is supported. The CM50C comes with a large variety of interfaces, including, for example, Digital Display Interfaces, HD Audio, PCI Express and Gigabit Ethernet. This enables implementing many functions on a very small form factor.

The processor’s 15 years long-term availability ensures an extended product life and future-safety for a wide range of applications. For less demanding applications, a standard COM Express variant without frame is also available.

Features:

  • Intel Atom E3900 series
  • Up to 8 GB DDR3 RAM with ECC
  • Intel VT-x virtualization support
  • Rugged COM Express Mini (VITA 59 RCE) type 10
  • Trusted Platform Module
  • Board Management Controller (SIL 2 certifiable)
  • Conduction cooling
  • -40°C to +85°C

Software Speeds Safety Certification for STM32-Based Systems

STMicroelectronics has announced new free software for its STM32 microcontrollers. The functional-safety design package cuts complexity and IEC 61508 safety-certification costs for STM32-based safety critical applications. This resource is created for designers of STM32-based devices in the field of industrial controls, robots, sensors, medical, or transportation, which must be certified up to Safety Integrity Level (SIL) 2 or 3 of the recognized safety standard IEC 61508. ST’s STM32 SIL Functional-Safety Design Package simplifies system development and certification.

The SIL Functional-Safety Design Package comprises documentation and the X-CUBE-STL, a software Self-Test Library certified to IEC 61508 SIL3. The package is initially available for the STM32F0 series. ST will continue to introduce equivalent packages for all other series in the STM32 family throughout 2018 and 2019. There are currently more than 800 STM32 microcontroller variants.

ST’s STM32 SIL Functional Safety Design Package contains full documentation to support development of STM32-based embedded systems to meet IEC 61508 requirements for functional safety. The documentation comprises safety manuals that detail all applicable safety requirements, or conditions of use, with implementation guidelines to help developers certify their products to SIL 2 or SIL 3 in accordance with IEC 61508. Also included are the mandatory Failure-Modes Effects Analysis (FMEA), containing the detailed list of microcontroller failure modes and related mitigation measures, and Failure-Mode Effects and Diagnostics Analysis (FMEDA), which gives a static snapshot reporting IEC 61508 failure rates, computed at both the microcontroller and basic functions detail levels.

The software self-test library, X-CUBE-STL, is a software-based diagnostic suite for detecting random hardware failures in STM32 safety-critical core components comprising the CPU, SRAM, and Flash memory. The Diagnostic Coverage is verified by state-of-the-art ST proprietary fault injection methodology. Integrated with the familiar and proven STM32Cube workflow, it is application-independent thereby allowing use with any user application, and is delivered as compiler-agnostic object code.

TÜV Rheinland, a leading international certification institute for functional safety certification to relevant international standards, has positively assessed X-CUBE-STL-F0 according to the functional safety standard IEC 61508:2010. Detailed information of the certificate will be soon available on www.fs-products.com. Swiss-based sensor manufacturer Contrinex is the first to use ST’s Functional-Safety Design Package to certify safety products based on STM32F0 microcontrollers.

The Functional-Safety Design Package for STM32F0 microcontrollers is available from www.st.com, free of charge, subject to Non-Disclosure Agreement (NDA) with ST. Equivalent packages for other STM32 series will be introduced throughout 2018 and 2019.
