ISO 26262 Automotive Functional Safety—dsPIC33 DSCs
Achieve ISO 26262 Compliance With dsPIC33 DSCs for Functional Safety in Automotive Designs
Designing safe and reliable automotive applications to ensure customer safety is critical. To meet these rigorous safety requirements, we offer a broad portfolio of functional safety compliant/ready dsPIC33 Digital Signal Controllers (DSCs) that encompass the latest hardware safety features and support collateral to help you achieve ISO 26262 Automotive Safety Integrity Level (ASIL B) certification for your design. You can also achieve the higher ASIL C and ASIL D safety levels through decomposition.
You can use our dsPIC33C DSCs in safety-critical, high-performance embedded, sensor interfacing, digital power and motor control applications for the automotive market targeting ISO 26262 compliance.
Functional Safety Support With dsPIC33 DSCs
Many new dsPIC33 DSCs are qualified as functional safety compliant, which means they are designed by following the TÜV Rheinland-certified, ISO 26262-compliant development process.
Our AEC-Q100 Grade 0- and Grade 1-qualified dsPIC33 DSCs include the following resources to simplify safety certification of your automotive designs:
- Failure Modes, Effects and Diagnostic Analysis (FMEDA) report and Functional Safety Manual (FSM)
- Functional Safety Reference Application
- Application note: “ISO 26262 Functional Safety: Implementation of a Safety Element Out of Context” (AN3864)
- TÜV Rheinland-certified diagnostic libraries for designs targeting levels up to ASIL C*
- Supporting safety collateral, including pin FMEA and Dependent Failure Analysis (DFA)
- Functional safety-compliant co-operative scheduler
- Development ecosystem for functional safety applications with TÜV SÜD-certified MPLAB® XC16 compiler and a qualification package for the MPLAB ecosystem
*Targeting ASIL C safety level is device dependent and requires adherence to ASIL decomposition techniques.

Functional Safety Development Ecosystem
When designing functional safety applications, using development tools that meet the requirements of safety standards can make it easier to create compliant systems. To help you with implementing system-level functional safety in your applications, we are TÜV SÜD-certified for our MPLAB® XC C compilers for several functional safety standards, and we provide the complete certification packages for the MPLAB development tool ecosystem to help you qualify your projects. The tool package includes:
- TÜV SÜD-certified MPLAB XC functional safety compiler (XC-DSC SW006024-FS and XC16 SW006022-FS)
- MPLAB Analysis Tool Suite Workstation License (SW006027-2)
- MPLAB X Integrated Development Environment (IDE), MPLAB debugger/programmers and associated documentation and reports for a fully qualified development environment to ease safety qualification

SAFERTOS® for Safety-Critical Applications
SAFERTOS, by WITTENSTEIN High Integrity Systems (WHIS), is an ISO 26262/IEC 61508 pre-certified safety Real-Time Operating System (RTOS) that is compatible with our dsPIC33 DSCs.
Achieving ASIL C and ASIL D Safety Levels
You can typically achieve higher safety levels through ASIL decomposition and redundancy.
ASIL C = ASIL B(C) + ASIL A(C)
ASIL D = ASIL B(D) + ASIL B(D), where the combination of the DSCs enables meeting the ASIL C or ASIL D safety goal
