In recent years, smart locks have become an important entry point for smart homes, with the market size continuously expanding. Previously, products mainly featured a single function of “fingerprint + password”; however, as users’ demands for security and interactive experience continue to rise, smart locks are rapidly evolving towards a three-in-one form of “lock + peephole + doorbell.” This multifunctional integration not only brings a more convenient application experience but also poses higher challenges for chips.
In this evolution, MCUs have become crucial, with demand primarily reflected in two directions: on one hand, there is a need for higher functional integration to support wireless communication, video processing, and security algorithms; on the other hand, it is essential to achieve lower power consumption under long standby conditions to ensure that battery life meets expectations.
In response to market trends, GigaDevice has launched three MCU products tailored for different scenarios of smart locks—GD32W515, GD32L233, and GD32FFPR, covering high-integration multi-functional solutions, ultra-low power designs, and core applications for fingerprint module control, laying a solid foundation for the continuous upgrade of smart locks.
