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, now available from Microchip Technology Inc.
The dsPIC33CH has 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 is designed specifically to facilitate independent code development for each core by separate design teams and allows seamless integration when brought together in one chip.
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. In addition, each of the new cores in the dsPIC33CH devices has been designed to provide more performance than current dsPIC DSC cores through: more context-selected registers to improve interrupt responsiveness; new instructions to accelerate digital signal processor (DSP) performance; and faster instruction execution.
“Customers tell us one of their biggest challenges is integrating software from multiple teams where one team is focused on the time-critical control code and another is working on the rest of the application,” said Joe Thomsen, vice president of Microchip’s MCU16 business unit. “We created this dual-core product to simplify that software integration and optimize the performance for math-intensive applications.”
The dsPIC33CH family delivers unprecedented integration in a small 5 by 5 mm package and includes features such as CAN-FD communications. To reduce system costs and board size, advanced peripherals are available to each core including high-speed ADCs, DACs with waveform generation, analog comparators, analog programmable gain amplifiers and high-resolution pulse width modulation (PWM) hardware. Having two cores, with dedicated peripherals, allows the cores to be programmed to monitor each other for functional safety reasons, facilitating robust system design.

Development Support
The dsPIC33CH is supported by Microchip’s MPLAB development ecosystem including Microchip’s free, downloadable and award-winning MPLAB X Integrated Development Environment (IDE) and MPLAB Code Configurator.
The dsPIC33CH Curiosity Board (DM330028) is a cost-effective and flexible platform, enabling customers to rapidly create a feature-rich prototype. The dsPIC33CH Plug-in Module (PIM) for motor control platforms (MA330039) is available for Microchip’s MCLV-2 and MCHV-2/3 systems. The dsPIC33CH PIM for general purpose platforms (MA330040) is now available for the Explorer 16/32 development board (DM240001-2).
Pricing and Availability
The dsPIC33CH is available in eight package variants. Variants include packages from 28 to 80 pins and as small as 5 by 5 mm. Flash memory sizes range from 64 to 128 KB.
