Functional Safety Support for Arm-based Microcontrollers and Processors

This white paper introduces functional safety concepts such as the hazard analysis and risk assessment, random and systematic faults, safety element out of context and IEC 61508 SIL and ISO 26262 ASIL ratings. Examples are provided of how the AM243x MCU and AM64x processor series assist system integrators in achieving functional safety goals through the use of an on-chip safety MCU and safety diagnostics.

Understanding Functional Safety FIT Base Failure Rate Estimates per IEC 62380 and SN 29500

Functional safety standards like International Electrotechnical Commission (IEC) 61508 (1) and International Organization for Standardization (ISO) 26262 (2) require that semiconductor device manufacturers address both systematic and random hardware failures. Systematic failures are managed and mitigated by following rigorous development processes. Random hardware failures must adhere to specified quantitative metrics to meet hardware safety integrity levels (SILs) or automotive SILs (ASILs). Consequently, systematic failures are excluded from the calculation of random hardware failure metrics.
