System developers designing high-end embedded controlapplications can benefit from a new Digital Signal Controller (DSC) with twodsPIC DSC cores in a single chip. The dsPIC33CH has one core that is designedto function as a master while the other is designed as a slave. The slave coreis useful for executing dedicated, time-critical control code while the mastercore is busy running the user interface, system monitoring and communicationsfunctions, customized for the end application.The dsPIC33CH is designed to facilitate independent codedevelopment for each core by separate design teams and allows seamlessintegration when they are brought together in one chip. The dsPIC33CH family isoptimized for high-performance digital power, motor control and other high-endembedded applications requiring sophisticated algorithms.
The dsPIC33CH product familyhas many features that help simplify functional safety certificationsfor ASIL-B and ASIL-C focused applications including: • Functional Safety Manual, FMEDA and DiagnosticSoftware available under NDA upon request to your local sales office• Learn more about 16-bit Functional Safety capabilities including hardware, software,and supporting collateral
