“In recent years, with the substantial improvement of people’s living standards, smart door locks, as the core product of home smart security, have been favored and sought after by many consumers, and have become a new outlet in the smart home industry. The traditional smart door lock solution needs to add additional security modules to realize the storage protection, encryption and decryption operations and security authentication of sensitive information such as keys, unlock passwords, fingerprint templates, etc., which is not only unfavorable for product miniaturization design, but also to a certain extent. There are security risks.

In recent years, with the substantial improvement of people’s living standards, smart door locks, as the core product of home smart security, have been favored and sought after by many consumers, and have become a new outlet in the smart home industry. The traditional smart door lock solution needs to add additional security modules to realize the storage protection, encryption and decryption operations and security authentication of sensitive information such as keys, unlock passwords, fingerprint templates, etc., which is not only unfavorable for product miniaturization design, but also to a certain extent. There are security risks. Based on Nations N32G4FRx/N32WB4x MCU, the single-chip security smart door lock solution launched by Dalian Da Shiping can integrate the originally physically independent smart door lock master control, security chip, fingerprint recognition, touch, Bluetooth and other functions into It is implemented in a single MCU chip, which saves the cost of the device and reserves more room for the design of door lock products.

Nationals Technology Co., Ltd. (Nations) was established in 2000. It is a leader in security chips and general-purpose MCUs in China. The company has the first domestic enterprise independent security chip attack and defense technology laboratory and post-doctoral research workstations in Beijing, Shanghai, Wuhan and Singapore. There are branches in other regions.
The N32G4FRx/N32WB4x used in this solution are high-performance MCUs specially designed by Nations for single-chip security smart door locks. It integrates fingerprint recognition algorithm components, security components, password components, voice components, low power control, touch components, optional Bluetooth components (N32WB4x comes with BLE5.0 Bluetooth components) and other components, equipped with embedded freeRTOS real-time operating system , can run OLED menu Display, voice navigation, fingerprint, touch and other human-computer interaction functions smoothly. And in the design, a non-contact function chip can be provided to achieve the best cost-performance ratio of the smart door lock solution.
