About Wireless MCU

Hangshun Wireless MCUs integrate high-performance 32-bit ARM Cortex-M cores with advanced RF transceivers to provide complete wireless connectivity solutions for IoT applications. The portfolio includes BLE 5.0 MCUs supporting 2Mbps high-speed mode, long range (Coded PHY), and extended advertising, as well as Sub-1GHz MCUs operating at 433/868/915MHz for long-range, low-power applications. These MCUs feature ultra-low power consumption with receive currents as low as 3mA and sleep currents below 1μA while maintaining RAM retention. The integrated protocol stacks include complete BLE stack supporting peripheral, central, broadcaster, and observer roles, as well as proprietary RF protocols for custom applications. RF performance is excellent with BLE sensitivity of -95dBm and Sub-1G sensitivity of -120dBm. Security features include hardware encryption (AES-128/256), secure boot, and true random number generator. The wireless MCUs are ideal for smart home devices, wireless sensors, asset tracking, health monitors, industrial IoT, and remote controls. Development is simplified with comprehensive SDK, protocol analyzers, and certified modules.

Frequently Asked Questions

Should I choose BLE 5.0 or Sub-1GHz for my application?

Choosing between BLE 5.0 and Sub-1GHz depends on application requirements: BLE 5.0 Advantages - Smartphone connectivity: Direct connection to iOS/Android devices

Ecosystem: Large ecosystem of compatible devices

Data rate: 2Mbps for fast data transfer

Interoperability: Standard protocol ensures compatibility

Certification: Easier regulatory certification

Best for: Consumer devices, phone accessories, smart home. Sub-1GHz Advantages - Range: 2-5x longer range than 2.4GHz

Penetration: Better through walls and obstacles

Power: Lower power for same range

Spectrum: Less crowded than 2.4GHz

Cost: Lower module cost for simple applications

Best for: Industrial sensors, smart metering, long-range monitoring. Comparison: Range (urban): BLE 30-50m, Sub-1G 100-500m

Range (rural): BLE 100m, Sub-1G 1-5km

Data rate: BLE 2Mbps, Sub-1G 50-500kbps

Power (TX): BLE 4mA, Sub-1G 25mA

Power (RX): BLE 3mA, Sub-1G 10mA. Decision factors: Need smartphone connectivity -> BLE

Need maximum range -> Sub-1G

High data rate required -> BLE

Simple sensor network -> Sub-1G

Consumer product -> BLE

Industrial application -> Sub-1G. Hangshun offers both options with similar MCU features.

Choose BLE for smartphone connectivity and high data rate; choose Sub-1G for maximum range and penetration.

What is the range of Hangshun wireless MCUs?

Wireless range depends on protocol, environment, and antenna design: BLE 5.0 Range - 1Mbps mode: Indoor 30-50m, Outdoor 100-150m

Coded PHY (125kbps): Indoor 100-200m, Outdoor 300-500m

Factors: 2.4GHz absorption by walls/water

Interference from WiFi/BLE devices

Antenna efficiency critical. Sub-1GHz Range - 433MHz: Urban 200-500m, Rural 1-3km

868/915MHz: Urban 100-300m, Rural 500m-2km

Factors: Lower frequency = better penetration

Less interference than 2.4GHz

Regional regulations limit power. Range extension techniques: Higher TX power (within regulatory limits)

Higher sensitivity receiver (lower dBm = better)

Directional antennas (Yagi, patch)

Mesh networking for multi-hop

Repeaters for coverage extension. Typical applications: Smart home (BLE): Room-level coverage

Industrial sensors (Sub-1G): Factory floor coverage

Asset tracking (BLE): Building-level

Smart metering (Sub-1G): Neighborhood-level. Antenna considerations: PCB antenna: Compact, lower efficiency

Chip antenna: Small, moderate efficiency

External antenna: Best performance, larger size. The actual range should be tested in the actual deployment environment.

BLE for room/building coverage; Sub-1G for long-range industrial; test in actual environment.

How do I optimize power consumption for battery-operated wireless devices?

Optimizing power for wireless battery devices requires system-level approach: 1) Duty cycling - Transmit/receive only when necessary

Sleep between transmissions

Typical duty cycle: 0.1% to 1%

2) Connection intervals - BLE: Longer intervals = lower power

Range: 7.5ms to 4s

Trade-off: Latency vs power

3) TX power optimization - Use minimum TX power for required range

BLE: -20dBm to +8dBm programmable

1dB reduction = ~10% power savings

4) Sleep modes - Deep sleep with RAM retention: <1μA

Wake on timer or external interrupt

Maintain connection state in RAM

5) Data aggregation - Collect multiple samples before transmission

Burst transmission more efficient than frequent small packets

Use notifications instead of polling. Power calculation example: Sensor reading every minute

BLE transmission: 10ms @ 5mA = 50μC

Sleep: 59.99s @ 5μA = 300μC

Average current: ~6μA

Battery life (CR2032, 225mAh): ~4 years. Additional optimizations: Reduce payload size

Use connection slave latency

Disable unused features

Optimize antenna matching. The Hangshun wireless SDK includes power profiling tools.

Use long connection intervals; minimize TX power; aggregate data; deep sleep between transmissions.
