With the improvement of technology, IoT has entered thousands of households. Daily household appliances are gradually connected through IoT, using millisecond-level intelligent linkage. As an important protective barrier of the home, door locks will enter the smart door locks era as well. The warming up of the smart door lock industry and landing of products in 2018 is the highlight of whole smart home industry.
System Structure
RTL8762EMF only provides Bluetooth data transmission function and Bluetooth communication function for smart locks.
RTL8762CKF is used as the main controller for smart locks, only for the functional coordination and basic business logic implementation of various peripheral modules, and does not undertake the implementation of system security policies or running fingerprint algorithms.
The RTL8772GWF, MCU Real-M300V 125MHz (compatible with Cortex-M55), Trust Zone, and other hardware-level security features are particularly suitable for the application of smart locks. Realtek, together with financial-grade security solution providers, offers customers a complete smart lock security solution.
Advantages of Solution
Supports Bluetooth 5.0 and above, ultra-low power consumption, combined with an ARM Cortex processor. Flexible GPIO design and sensitive reception range, widely used in all kinds of products.
Use one BLE SoC to actualize a single-chip solution, realize BLE connection and other functions, with high degree of integration, extremely reduce the cost of solution.
Full-featured SDK/HDK, with supporting mobile phone APP engineering, which greatly reduces a customer's development workload and accelerates the implementation of a project.
