US Microchip Technology Releases New Digital Signal Controller

Microchip Technology Inc. has released a new digital signal controller that uses a single-chip, dual dsPIC DSC core configuration and will be used by system developers who design high-end embedded control applications. According to the design, the two cores of the dsPIC33CH One is the main core and one is the deputy core. The deputy core is used to execute the time-critical special control code. The main core is responsible for running the user interface, system monitoring and communication functions. It is tailor-made for the terminal application. The dsPIC33CH is also specially designed. This allows different design teams to separately develop code for each core separately, and seamlessly integrates the two cores into a single chip.

The dsPIC33CH family is optimized for high-performance digital power supplies, motor control and other applications that require precision algorithms, including wireless power supplies, server power supplies, drones and automotive sensors.

In automotive exhaust fans or automotive pumps, the secondary core is dedicated to managing time-critical speed and torque control, main core management controller area network flexible data rate (CAN-FD) communication, system monitoring and diagnostics. Both cores Collaborate seamlessly, enabling advanced algorithms to increase efficiency and speed of response. In addition, each new core in dsPIC33CH devices is designed to provide higher performance than current dsPIC DSC cores in the following ways: 1) More based on the environment Selected registers to increase interrupt response speed; 2) New instructions to improve digital signal processor (DSP) performance, and 3) Faster instruction execution speeds.

The dsPIC33CH family offers unprecedented levels of integration. Although the package is only 5 x 5 mm in size, it includes features such as CAN-FD communications. To reduce system cost and board size, each core provides advanced peripherals, including high-speed ADCs. Waveform generation DACs, analog comparators, analog programmable gain amplifiers and high-resolution pulse width modulation (PWM) hardware. Dual cores and dedicated peripherals allow the kernel to be programmed to monitor each other to ensure functional safety. Robust system design.
