Representative models: STM32H5.

Cortex-A7: Designed for higher-performance microprocessor (MPU) needs.

Representative models: STM32MP1.

2. Classification by Use Case

High-Performance Series (e.g., STM32H7, STM32F7): Designed for applications requiring     high computational power and real-time responsiveness, such as industrial automation and image processing.

Mainstream Series (e.g., STM32F1, STM32G4): Balances performance and cost to meet most general-purpose embedded needs.

Ultra-Low-Power Series (e.g., STM32L0, STM32L4): Ideal for battery-powered devices like wearables and sensor nodes.

Wireless Series (e.g., STM32WB, STM32WL): Integrates Bluetooth or LoRa communication modules for IoT devices.

Technical Features

1. High Performance Combined with Low Power

The STM32     series is based on ARM Cortex-M cores, offering options ranging from     simple tasks to complex computations.

Ultra-low-power     design makes it ideal for battery-operated devices with multiple low-power     modes (Sleep, Stop, Standby).

2. Rich Peripheral Support

A wide range of peripherals are integrated, including GPIOs, ADC/DACs, PWMs, I2C, SPI,     UARTs, etc., enabling complex hardware interactions.

High-end products support advanced features like Ethernet controllers, USB OTG     interfaces, and high-speed storage interfaces (e.g., SDIO).

3. Strong Development Ecosystem

Free development tools such as STM32CubeIDE and graphical configuration tools like STM32CubeMX simplify the development process.

Extensive software libraries like HAL (Hardware Abstraction Layer) and LL (Low-Layer) libraries allow developers to get started quickly.

4. Security and Reliability

Some products support TrustZone technology to create a trusted execution environment.

Integrated Error Correction Code (ECC) memory improves data security.

5. Flexible Expansion and Innovation

Supports edge AI deployment through tools like STM32Cube.AI, enabling machine     learning models to run on microcontrollers for smart edge devices.

Typical Application Areas

1. Industrial Automation

Widely used in PLC controllers, motor drives, and industrial sensors for real-time data     acquisition and control.

The STM32G4 series is particularly suited for motor vector control and power     management in complex industrial applications.

2. Consumer Electronics

Applied in smart home devices (e.g., smart bulbs), wearables (e.g., smartwatches), and smart speakers.

3. Medical Devices

Used in glucose meters, ECG monitors, and other medical devices for data     acquisition and analysis with high precision and low power consumption.

4. Automotive Electronics

Found in engine management systems (EMS), battery management systems (BMS), in-car     entertainment systems, and ADAS modules.

5. IoT and Edge Computing

Wireless series like WB/WL integrate Bluetooth or LoRa communication modules for IoT device data transmission.

Edge AI deployment enables real-time facial recognition or behavior analysis in smart surveillance cameras.

6. Education and Research

As an embedded development learning platform, the STM32 is widely used in university     courses and research projects.
