Ultra Low Power Smart Door Lock Solution

At present, the smart door lock industry solutions to achieve the overall function of high power consumption, the common program to MCU polling to open the card reading module, shielding touch keys, MCU high-frequency work, resulting in a significant reduction in the service life of the product.

Si24R1-2.4G ISM band ultra-low power consumption cost-effective solution, Si522A + Si12T chip combination using the new ACD automatic card search, card probe before automatically shielding the touch chip function, the whole process without MCU intervention, the MCU only need to judge the IRQ to make the corresponding operation can be. The new realization of the overall standby power consumption of the smart door lock is reduced to less than 10uA.
