Dual-Core Architecture Driving Efficient Motor Control Development Deployment

1. Positioning and Value of the CGH Series
In the process of motor control development, a highly compatible, stable, and reliable Evaluation Board (EVB) is a key tool for shortening development cycles and reducing debugging costs. As an essential platform for chip validation, an EVB efficiently and accurately exposes core signals through standard interfaces, enabling engineers to quickly complete performance verification, control algorithm tuning, and system integration. This eliminates the complexity of building a test environment from scratch, significantly improving overall R&D efficiency.

The CGH series BLDC motor control EVBs introduced here are specifically designed for Hall-based motor control applications. The series includes four core models: CGH001A, CGH021A, CGH061A, and CGH081A.

These products are differentiated to support various power levels and application scenarios, effectively addressing challenges in compatibility, debugging complexity, and system stability—thereby accelerating project deployment.

2. Core Architecture and Performance Highlights

The CGH Series adopts a dual-core cooperative architecture, integrating general-purpose control and dedicated motor driving at the hardware level:
👉 8051 MCU + Motor Driving Engine (MDE)
This architecture maintains a low development barrier while optimizing motor control performance.

2.1 8051 MCU Module
1) Built-in 1T 8051 core, compatible with MCS®-51 architecture, Operating voltage: 4.5V–5.5V, mature, stable, and easy to develop
2) Integrated memory: 8KB Flash, 256B IRAM + XRAM
Supports 13 interrupt sources / 4 priority levels, meeting real-time control requirements
3) Peripheral resources:
• 8-channel 10-bit ADC
• Full-duplex UART
• Hardware multiplier/divider

2.2 Motor Driving Engine (MDE) Module
Positioning: The MDE handles real-time critical motor control tasks (PWM generation and commutation logic), significantly reducing MCU workload.

Features:

1) Supports:

• SVPWM (Space Vector PWM)

• Compatible with sinusoidal and trapezoidal (square wave) drive modes

2) Position detection:

• Supports Hall latch inputs

• Provides speed and position detection capabilities

3) Control capability:

• Supports programmable phase/angle control (ideal for applications requiring high control precision)

4) Dual protection mechanisms： Supports both digital and analog overcurrent protection (OCP)

3. Series Models and Hardware Differences

The CGH Series is designed with graded power-driving capabilities. Different EVB models vary in gate driver configuration and voltage tolerance.

Each chip and EVB can be precisely matched to different power application scenarios, such as: Hall-based fans, Air-conditioning fan systems, Stand fans / ceiling fans, Air-conditioner drainage pumps…
