Microchip Technology 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.
The dsPIC33CH devices are optimized for high-performance digital power, motor control, and other high-end embedded applications requiring sophisticated algorithms. This includes applications such as wireless power, server power supplies, drones, and automotive sensors. For example, in a digital power supply, the slave core manages the math-intensive algorithms, while the master core independently manages the PMBus™ protocol stack and provides system monitoring functions, increasing overall system performance and responsiveness. Distributing the overall workload across two DSC cores in a single device enables higher power density through higher switching frequencies, leading to smaller components. The dsPIC33CH family was designed for live updating of the system, which is especially important for power supplies where firmware updates must be made with zero downtime.
For design flexibility, the dsPIC33CH devices are available in eight package variants, from 28-pins to 80-pins, and as small as 5mm x 5mm. Memory sizes range from 64KB to 128KB of Flash.
