dsPIC33A DSC Class B Software Library

The dsPIC33A Class B Software Library* is a diagnostics and self-test suite designed to help developers meet IEC 60730 and IEC 60355 Class B safety standards for home appliances and other safety‑critical embedded applications. Built specifically for the dsPIC33A family of Digital Signal Controllers (DSCs), this library leverages several on-chip hardware safety features and provides robust verification of essential DSC modules to ensure the reliable operation of end products.

Overview

This library* implements a comprehensive set of diagnostic APIs that can be seamlessly integrated into user applications, enabling compliance with Class B functional safety requirements.

These diagnostics perform runtime and startup tests on critical DSC resources, helping developers reduce development time while meeting safety standards.

*VDE and UL Certification is in progress
