  • Also provides a range of product lifecycle support and certification

STMicroelectronics has released three functional-safety packages that simplify the development of safety-critical industrial, medical, consumer and automotive products based on STM32 and STM8 microcontrollers and microprocessors.

The packages contain the resources required by the developers to comply with applicable IEC and ISO specifications. A diverse range of over 1000 STM32 devices and the STM8 microcontroller family including STM8AF automotive-qualified devices provide a wide choice and affordability.

All embedded developers can leverage these packages to overcome engineering challenges, accelerate time to market and minimize certification costs.

Meeting safety and efficiency

Targeting industrial applications, the X-CUBE-STL package is certified by TÜV Rheinland according to IEC 61508 SC3 and allows the use of STM32 devices for safety implementation of functions up to Safety Integrity Level SIL-2 or SIL-3.

For developers of safety-critical home appliances, X-CUBE-CLASSB is certified by Underwriters Laboratories (UL) according to IEC 60335-1 and 60730-1.

The STM8-SafeCLASSB package enables appliance developers to leverage the high efficiency, low cost and low power consumption of STM8 devices.

X-CUBE-STL, X-CUBE-CLASSB, and STM8-SafeCLASSB contain application-independent self-test libraries for core CPU and memory components, as well as necessary safety documentation.

The STM8A-SafeASIL package provides the documentation needed for automotive applications up to ASIL B. Suitable for use within an ISO26262-compliant software development process, this package helps users to realize the software self-test library required by the STM8AF safety manual.

Wide support and availability

Several ST Authorized Partners provide associated services and support for every stage of the development lifecycle, including defining safety requirements, implementing safety diagnostics, test and validation, and product certification. They all offer a safety RTOS for STM32 microcontrollers and microprocessors. Also, functional-safety certified compilers for STM8 and STM32, software, design and engineering services, reference platforms, and training facilities are provided to support customers’ projects.

The new functional-safety software packages are available now, free of charge.

X-CUBE-STL is available for most STM32 variants, with packages for STM32L5, dual-core STM32H7, and STM32MP1 devices scheduled for Q4 2020. The X-CUBE-CLASSB  is available for STM32F0, G0, F1, F3, G4, F2, F4, F7, H7, L0, L1, L4 and WB.

The STM8-SafeCLASSB package is also available.
