IEC 60730 Class A and Class B
We offer a broad portfolio of dsPIC33 DSCs with a range of hardware safety features that support software routines, which you can readily integrate into your designs to simplify compliance to IEC 60730 Class B safety requirements.
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

This quick reference guide provides overview of supported functional safety standards, safety documentation, diagnostic libraries, development tools and safety ready/compliant product families, helping you accelerate development and compliance efforts.
Simplify Higher Safety Compliance With Decomposition
Are you worried about the increased design complexity and developmental costs of meeting higher safety standards? Our application note discusses how to use the decomposition method when creating an ASIL D/SIL 3 E-Fuse application to reduce software development effort (equivalent to implementing ASIL B/SIL 2 twice), deliver substantial cost savings and provide scalability. Explore the benefits of this modular solution and simplify the development of your next higher safety compliance design.

FAQs
Which dsPIC33 devices support ISO 26262, IEC 61508 and IEC 60730 functional safety applications?
Which dsPIC33 devices support ISO 26262, IEC 61508 and IEC 60730 functional safety applications?
dsPIC33C and dsPIC33A DSCs are designed to support functional safety applications. For ISO 26262 and IEC 61508, these devices target up to ASIL B and SIL 2 at the device level, with higher safety levels achievable through decomposition at the system level. For IEC 60730, they target Class B using the available diagnostic libraries and safety resources. Availability varies by device; refer to the functional safety collateral for the target part number.
What Automotive Safety Integrity Levels can dsPIC33 DSCs support in automotive designs?
What Automotive Safety Integrity Levels can dsPIC33 DSCs support in automotive designs?
dsPIC33 DSCs are designed to support automotive functional safety designs targeting up to ASIL B at the device level. Higher safety levels, such as ASIL C or ASIL D, can be addressed through decomposition, for example, combining independent ASIL B safety elements as part of the system architecture.
How can dsPIC33 DSCs be used in IEC 61508 SIL 2 industrial applications?
How can dsPIC33 DSCs be used in IEC 61508 SIL 2 industrial applications?
For industrial functional safety, dsPIC33 DSCs target IEC 61508 SIL 2 applications and help address higher SIL goals through combination at the system level. We provide safety collateral such as FMEDA reports, functional safety manuals, diagnostic software libraries and qualified development tools to help customers design IEC 61508-oriented industrial applications.
What hardware safety features are integrated into dsPIC33 DSCs for fault detection and reliable operation?
What hardware safety features are integrated into dsPIC33 DSCs for fault detection and reliable operation?
Depending on the device, dsPIC33 DSCs include hardware safety features such as Flash Error Correction Code (ECC), RAM Built-in Self-Test (BIST) or RAM ECC, Cyclic Redundancy Check (CRC), Watchdog and Deadman timers, fail-safe clock monitoring, clock deviation detection, power or reset monitoring, error traps, protected memory regions and peripheral or General-Purpose Input/Output (GPIO) monitoring. Some dsPIC33A devices include features such as Peripheral Access Control (PAC), an I/O integrity monitor, a performance monitor unit, RAM ECC, core voltage monitoring and backup clock support.
