Smart Door Lock Solution Based on GD32 MCU
Fingerprint recognition, touch pads, and card swiping are now standard functions for smart door locks. Smart door locks have evolved from single lock function to "3-in-1" products that further integrated peephole and doorbell, which are now more demanding on chip function, performance, and peripheral interfaces. The requirements on MCUs are evolving towards two main directions, one is the higher integration of functions and the other is lower power in deep sleep mode.GigaDevice launches a "3-in-1" GD32W515 for smart lock main boards and the ultra-low power GD32L233 that features overall smart door lock control and functions from the front panel to the back panel. GigaDevice also releases the GD32FFPR for fingerprint modules that can be used with fingerprint sensors enabling fingerprint recognition.
