Hangshun Products

Hangshun offers four main MCU categories designed for different applications: 1) General Purpose MCU - versatile 32-bit ARM Cortex-M0/M3/M4 microcontrollers for embedded systems, industrial control, and consumer electronics; 2) Touch Control MCU - integrated capacitive touch sensing with up to 24 channels, water rejection technology, and low power consumption for HMI applications; 3) Motor Control MCU - dedicated MCUs with integrated gate drivers, advanced PWM units, and hardware acceleration for BLDC, PMSM, and stepper motor control; 4) Wireless MCU - BLE 5.0 and Sub-1GHz connectivity solutions for IoT applications with ultra-low power consumption. Each category is optimized for specific use cases while maintaining the common ARM ecosystem compatibility.

Select General Purpose for standard embedded applications, Touch Control for HMI interfaces, Motor Control for drives, or Wireless for IoT connectivity.

Choosing the right Hangshun MCU category depends on your application requirements: 1) General Purpose MCU - choose when you need standard processing with rich peripherals (UART, SPI, I2C, ADC, timers) without specialized features; suitable for industrial control, data acquisition, and general embedded systems; 2) Touch Control MCU - select when your application requires capacitive touch interface (buttons, sliders, wheels); ideal for home appliances, consumer electronics, and industrial panels; includes water rejection for kitchen applications; 3) Motor Control MCU - required for motor drive applications (BLDC, PMSM, stepper); features integrated drivers and control algorithms; perfect for fans, pumps, power tools, and servo systems; 4) Wireless MCU - essential for IoT applications requiring BLE 5.0 or Sub-1G connectivity; best for smart home, wireless sensors, and remote monitoring. Consider your primary function first, then evaluate peripheral requirements and power constraints.

Identify your primary application need (general processing, touch interface, motor control, or wireless), then browse the corresponding category for specific models.

Hangshun MCUs use three ARM Cortex-M core variants with different performance characteristics: 1) Cortex-M0 - entry-level 32-bit core, up to 48MHz, 0.9 DMIPS/MHz, simplest architecture with smallest code footprint, ideal for cost-sensitive applications with basic processing needs; 2) Cortex-M3 - mainstream performance core, up to 72MHz, 1.25 DMIPS/MHz, includes hardware divide and single-cycle multiply, better interrupt handling with NVIC, suitable for medium-complexity applications requiring real-time response; 3) Cortex-M4 - high-performance core with DSP capabilities, up to 168MHz, 1.25 DMIPS/MHz, includes single-precision FPU, DSP instructions (SIMD, MAC), and advanced debug features, perfect for applications requiring signal processing, complex algorithms, or floating-point calculations. Power consumption increases with performance: M0 < M3 < M4. Price follows the same trend. Select based on your processing requirements, algorithm complexity, and power budget.

Choose M0 for simple control tasks, M3 for mainstream applications, M4 for DSP and complex algorithms requiring floating-point operations.

Home appliance applications typically require a combination of Hangshun MCU categories: 1) Touch Control MCU - ideal for control panels with capacitive touch buttons and displays; water rejection features are essential for washing machines and kitchen appliances; supports overlay materials up to 5mm thick; 2) Motor Control MCU - required for appliances with motors (washing machine drums, refrigerator compressors, air conditioner fans, vacuum cleaners); integrated algorithms simplify development; 3) General Purpose MCU - suitable for simpler appliances without motors or touch interfaces (microwave ovens, rice cookers); cost-effective solution with sufficient peripherals. Many modern appliances use multiple MCUs: Touch MCU for the user interface, Motor Control MCU for the drive system, and General Purpose MCU for system management. Wireless MCUs are increasingly used for smart home connectivity and remote monitoring.

Use Touch Control MCU for panels, Motor Control MCU for drives, and General Purpose MCU for system control in home appliances.

Hangshun Wireless MCUs combine microcontroller and RF connectivity in a single chip: 1) BLE 5.0 variants - support 2Mbps high-speed mode, long range (Coded PHY with 4x range), extended advertising, and multiple simultaneous connections; TX power adjustable from -20dBm to +8dBm; RX sensitivity -95dBm; 2) Sub-1G variants - operate at 433/868/915MHz with -120dBm sensitivity and +20dBm TX power; better penetration through walls and longer range than 2.4GHz; 3) Ultra-low power - BLE: 3mA RX, 4mA TX, <1μA sleep with RAM retention; Sub-1G: 10mA RX, 25mA TX at +10dBm; 4) Integrated protocol stacks - BLE peripheral/central/broadcaster/observer roles, proprietary RF protocols; 5) Coexistence features - integrated balun, antenna diversity support. Applications include smart home devices, wireless sensors, asset tracking, health monitors, and industrial IoT. Development kits include RF evaluation boards and protocol analyzers.

Select BLE 5.0 for smartphone connectivity and interoperability; choose Sub-1G for long-range, low-power sensor networks.
