Article Overview

This article introduces Microchip 's dsPIC33A Digital Signal Controller ( DSC ) , a high-performance real-time control and edge intelligence platform designed specifically for the AI era . This controller integrates a high-speed DSP engine, a double-precision FPU , an AI- grade safety module, and leading analog peripherals, providing a core real-time control solution for scenarios such as AI server power supplies, edge AI/ML , and intelligent sensing . Furthermore, the dsPIC33A DSC , with its powerful parallel processing capabilities and instruction set designed specifically for machine learning, is an ideal choice for edge AI/ML applications.

AI is reshaping the future of data centers, power architectures, industrial automation, and smart devices. From the high-power-density power supplies of large AI servers to the real-time sensing and intelligent decision-making of edge devices, the demands on computing performance, energy efficiency, response speed, and security are increasing dramatically.

The Digital Signal Controller ( DSC ) serves as the " real-time brain of an AI system + high-speed sensing front-end + secure and reliable execution core." It's not used to train large models, but rather to enable AI systems to "see faster, calculate more accurately, and react more promptly" in the real world. The DSC plays several key roles in AI server power supplies, edge AI/ML, and intelligent sensing .

In this episode, Microchip experts will provide a detailed introduction to the new dsPIC33A Digital Signal Controller ( DSC ) , designed specifically for this AI- driven era. It deeply integrates a high-speed DSP engine, a dual-precision FPU , an AI -level safety module, and industry-leading analog peripherals, providing enterprises with an AI-ready real-time control core to help their products stand out in the wave of intelligentization.

Guest Introduction:

Leo Wang , Marketing Development Manager , dsPIC Business Unit

Leo Wang is currently the Marketing Development Manager for the dsPIC Business Unit at Microchip Technology Inc.'s Shanghai branch . He joined Microchip in 2008 and has over 20 years of experience in the MCU/DSC industry . Prior to that, he worked at Renesas Electronics, where he provided technical support and promoted MCU products.

Wang Anming has extensive experience in marketing and promotion, having previously been responsible for markets such as electricity meters, industrial control, motor drives, and digital power supplies. Currently, he is in charge of the promotion and marketing of digital power supply products in China at Microchip .

Wang Anming graduated from Soochow University with a bachelor's degree in Electronic Information and Science and Technology.

The interrupt entry speed of the dsPIC33A is 2.38 times that of a general-purpose MCU .

This is thanks to:

Multiple working registers
Single-step ISR switching mechanism

Compared to general-purpose MCUs that require multiple push/pop operations , the dsPIC33A can enter interrupts faster, making it suitable for timing-sensitive applications, such as:

Overcurrent protection
Motor commutation
Digital power fast loop

The dsPIC33AK series chips support capacitive touch functionality and have an integrated on-chip touch controller (ITC) module, which mainly has the following functions:

It is equipped with a dedicated hardware engine to handle capacitive sensing, which does not require CPU resources and improves operating efficiency.
It provides a pre-defined, hard-coded touch detection process for beginners, lowering the development threshold.
Supports users' innovative needs, allowing them to define their own capacitive sensing detection logic and processes.
It can be adapted to multiple trigger sources and supports flexible configuration of capacitance parameters to meet the touch needs of different scenarios.
The speed of touch signal acquisition and processing is improved by using a 40MHz high-speed ADC , reducing the response latency of touch operations.
By leveraging software-coded sequence logic, sensor signal processing can be completed automatically, simplifying the development process.

With the help of this ITC module, users can flexibly complete touch and sensor-related designs.

Some trends in the development of AI server power supplies:

For example, higher energy efficiency, with peak efficiency improved from Platinum to Titanium, and now to Titanium Plus.
With ever-increasing power density, a single power supply cabinet can now provide more than 30KW of power .
Higher performance requires faster processing speeds to meet the demands of large-scale computing power.
Strengthen security requirements, including sensitive data handling, identity verification, and prevention of cyberattacks / data breaches, etc.
