Smart Locks with Super-Low-Power Wi-Fi and BLE

Renesas/Dialog Semi's smart lock solution features fingerprint control, low-power Bluetooth®, and low-power Wi-Fi options. The demand for smart locks is a rapidly growing segment for the home and building automation industries and 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. 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 a small, low-power 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. 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) sensors are also used for a complete compact design.
