dsPIC33CH Dual Core Digital Signal Controllers Microchip Technology dsPIC33CH Dual Core Digital Signal Controllers combine two dsPIC DSC cores into a single chip. The dsPIC33CH Controllers have one core that is designed to function as a master while the other is designed as a slave. The slave core is useful for executing dedicated, time-critical control code while the master core is busy running the user interface, system monitoring, and communications functions, customized for the end application.
