DSPIC33CH in PIC Microcontrollers Family
The dsPIC33CH family from Microchip Technology is a high-performance 16-bit dual-core digital signal controller series designed for time-critical embedded systems. Featuring one Master core and one Dedicated Slave core, these controllers allow for the separation of control code and time-sensitive mathematical algorithms. Primarily utilized in high-speed power conversion, motor control, and functional safety applications, the family integrates hardware-based features to simplify ISO 26262 and IEC 61508 compliance while delivering near-zero latency processing.
