Smart lock with super-low power Wi-Fi and BLE

The demand for smart locks is a rapidly growing segment for the home and building automation industries. These locks need to be able to communicate with a smart home or building via fingerprint recognition and/or with a mobile phone using a common wireless communication protocol such as Bluetooth® or Wi-Fi. This smart lock solution features fingerprint control, low power Bluetooth and low power Wi-Fi options. The DA16600 low power Wi-Fi plus low power Bluetooth Low Energy (LE) module, DA16200 low power Wi-Fi networking system-on-chip (SoC) and DA14531 SmartBond TINY™ Bluetooth LE module provide the smallest and lowest Bluetooth 5.1, ultra-low power Wi-Fi SoC for battery powered Internet of Things (IoT) devices. Additionally, the GreenPAK™ family of cost-effective NVM programmable devices provides features such as a motor driver and LED control and the RX651 high-performance, low pin count, 32-bit microcontroller (MCU) is available to design in a fingerprint module for the algorithm design. A wide input range ultra-low quiescent current LDO and Time of Flight (ToF) sensor are also used for a complete compact design.
