Microchip TechnologyDSPIC33CH64MP202-I/SSMicrocontrollers - MCUs

System developers designing high-end embedded control applications can benefit from a new Digital Signal Controller (DSC) with two dsPIC DSC cores in a single chip. The dsPIC33CH has one core that is designed to function as a main core while the other is designed as a secondary core. The secondary core is useful for executing dedicated, time-critical control code while the main core is busy running the user interface, system monitoring and communications functions, customized for the end application.

The dsPIC33CH is designed to facilitate independent code development for each core by separate design teams and allows seamless integration when they are brought together in one chip. The dsPIC33CH family is optimized for high-performance digital power, motor control, advanced sensing and control, and general-purpose high-end embedded applications requiring sophisticated algorithms.

The dsPIC33CH product family has many hardware features that help simplify functional safety certifications for ASIL-B/-C and SIL-2/-3 focused automotive and industrial safety-critical applications. The family offers ISO 26262 and IEC 61508 Functional Safety packages containing FMEDA report, safety manual, diagnostic libraries and more.
