IEC 61508 Industrial Functional Safety Ready—dsPIC33 DSCs
Industrial Functional Safety DSCs for IEC 61508-Compliant Designs
The growing need for functional safety in industrial systems adds more complexity for embedded engineers. Designing safety-critical industrial applications that comply with the IEC 61508 safety standard can reduce the risk of industrial accidents. We designed our devices for reliable operation in harsh environments, making it easy to develop high-performance embedded, sensor interfacing, real-time control and automation, digital power and motor control applications targeting SIL 2 compliance. You can achieve the higher SIL 3 level through decomposition. Many new dsPIC33 DSCs are qualified as functional safety compliant, meaning they are designed by following the TÜV Rheinland-certified, IEC-61508-compliant development process.
Simplifying IEC 61508 Functional Safety Design and Certification
Our broad portfolio of IEC 61508 functional safety-ready and compliant dsPIC33 Digital Signal Controllers (DSCs) offers hardware safety features and functional safety resources to simplify designing your safety-critical industrial applications.
Note: SIL 3 compliant diagnostic libraries are available for many devices. Targeting higher safety level is device dependent and requires adherence to SIL decomposition techniques.
We have implemented a TÜV Rheinland-certified Functional Safety Management System (FSMS) that covers up to and includes IEC 61508’s Safety Integrity Level 3 (SIL 3) and Systematic Capability 3 (SC 3).
Simplify SIL 3 Safety Compliance with Decomposition
Are you worried about the increased design complexity and developmental costs of meeting the IEC 61508 SIL 3 standard? Our white paper discusses how to use the decomposition method when creating an SIL 3 E-Fuse application to reduce software development effort (equivalent to implementing SIL 2 twice), deliver substantial cost savings and provide scalability. Explore the benefits of a modular solution and simplify the development of your next IEC 61508 SIL 3-compliant design.

Readiness Status for IEC 61508 Functional Safety-Ready dsPIC33 DSCs
Functional Safety Development Ecosystem
When you are designing functional safety applications, using development tools that meet the requirements of safety standards can make it easier for you to create compliant systems. To help you with implementing system-level functional safety in your applications, our MPLAB® XC C compilers are TÜV SÜD-certified for several functional safety standards. We also provide the complete certification packages for our MPLAB development tools ecosystem to help you qualify your projects. The tools package includes:
- TÜV SÜD-certified MPLAB XC functional safety compiler
- MPLAB Analysis Tool Suite
- MPLAB X Integrated Development Environment (IDE), debuggers/programmers and the related documentation and reports
Tools and Software
- Development Environment
- Design Resources
MPLAB X IDE is a highly configurable software platform that provides powerful, free tools for developing, debugging and qualifying embedded designs that use microcontrollers and digital signal controllers.
The MPLAB XC-DSC C Compiler is a full-featured, optimizing compiler that translates standard ANSI C programs into Digital Signal Controller (DSC) device assembly language sources. This compiler also supports many command-line options and language extensions that allow full access to the DSC device hardware capabilities and gives users fine control of the compiler code generator.
MPLAB Code Configurator supports 8-bit, 16-bit and 32-bit PIC® microcontrollers. MCC is incorporated into both the downloadable MPLAB X Integrated Development Environment (IDE) and the cloud-based MPLAB Xpress IDE.
MPLAB Tools for VS Code are a set of extensions that integrate the MPLAB development ecosystem with VS Code, offering a seamless and efficient environment for developing designs based on Microchip devices.
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
