The Bluetooth smart door lock is an innovative locking solution that seamlessly combines modern technology with convenient and secure features, empowering users to manage security in a new way. Utilizing Bluetooth technology, users can easily manage and unlock the door lock through a smartphone app, passcode, or traditional key. The Bluetooth connection not only ensures quick response within short distances but also significantly enhances security. The installation process is simple and requires no additional wiring, making it an ideal choice for upgrading home or office door locks.
Realtek's chip series provides perfect support for various smart door lock products, benefiting both entry-level and advanced models with their low power consumption and the strong advantages of stable Bluetooth connectivity. Realtek offers comprehensive development kits and detailed documentation, enabling customers to effortlessly complete function development, test validation, and mass production testing. We ensure that customers receive fast and high-quality support at every stage, from solution selection to certification services.
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), supports hardware-level security features such as Trust Zone and has obtained PSA-L2 certification. It is particularly suitable for smart door lock applications. Realtek, together with financial-grade security solution providers, offers customers a complete smart lock security solution.
Advantages of Solution
