Smart Lock with Super-Low Power Wi-Fi and Bluetooth Low Energy

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 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.

System Benefits​:

• Includes the world’s smallest and lowest power Bluetooth 5.1 system-on-chip
• Ultra-low power Wi-Fi SoC for battery-powered IoT devices
• High-performance 120MHz low pin count MCU for adding a fingerprint module
• Programmable mixed-signal matrix enables innovators to integrate many system functions into a single custom circuit

Target Applications:

• Smart homes
• Smart buildings
