The dsPIC33CH family is optimised for applications requiring sophisticated algorithms, including 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.
In an automotive fan or pump, the Slave core is dedicated to managing time-critical speed and torque control while the master manages the Controller Area Network Flexible Data rate (CAN-FD) communications, system monitoring and diagnostics. The two cores work seamlessly together, enabling advanced algorithms to improve efficiency and responsiveness.
The dsPIC33CH is supported by Microchip’s MPLAB® development ecosystem including Microchip’s MPLAB® X Integrated Development Environment (IDE) and MPLAB Code Configurator.
In terms of hardware support, Microchip's offering includes:
- dsPIC33CH Curiosity Board (DM330028 ; $34.99 each)
- dsPIC33CH Plug-in Module (PIM) for motor-control platforms ( MA330039; MCLV-2 and MCHV-2/3 versions; $25.00 each)
- dsPIC33CH PIM (MA330040; for general-purpose platforms and Explorer 16/32 development board; $25.00 each)
The dsPIC33CH is available in eight package variants, from the 28-pin dsPIC33CH64MP202, to variants with 80 pins and variants as small as 5 x 5 mm. Memory sizes range from 64 to 128 KB of Flash.
