The packages are available free-of-charge and contain resources applicable to IEC and ISO specifications.

X-CUBE-STL is aimed at industrial applications and is certified by TÜV Rheinland according to IEC 61508 SC3. Ttogether with the Condition of Use of the Safety Manual, it allows the use of STM32 devices for the implementation of functions up to Safety Integrity Level SIL-2 or SIL-3.
It is available immediately for most STM32 variants, although packages for STM32L5, dual-core STM32H7 and STM32MP1 are scheduled for Q4 2020.

X-CUBE-CLASSB is certified by Underwriters Laboratories (UL) according to IEC 60335-1 and 60730-1.
It is available for STM32F0, G0, F1, F3, G4, F2, F4, F7, H7, L0, L1, L4 and WB.STM8-SafeCLASSB is available for appliance developers using 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,” according to ST.

STM8A-SafeASIL package provides documentation for automotive applications up to ASIL B. “Suitable for use within an ISO26262-compliant software development process, this package helps users to realise the software self-test library required by the STM8AF safety manual,” said the company.X-CUBE-STL and STM8A-SafeASIL are subject to non-disclosure agreements (NDAs).“ST authorised partners provide associated services and support, including defining safety requirements, implementing safety diagnostics, test and validation, and product certification,” said ST. “These include Embedded Office, Microsoft, Arm, Segger and Wittenstein, which all offer a safety RTOS for STM32 microcontrollers.”Also, IAR Systems and Arm provide functional-safety certified compilers for STM8 and STM32. Embedded Office, Hitex, innotec, MESCO and NewTec provide software, design and engineering services, reference platforms, and training facilities to support customers’ projects.Industrial, medical, consumer and automotive end-used products are foreseen.
