Low Power Wi-Fi

Wi-Fi smart door locks are becoming increasingly popular in Smart Homes. In a typical smart lock, the high current motor and Wi-Fi are the key sources of battery drainage. As a result, the battery only lasts up to a few weeks. Replacing batteries on regular basis is time consuming, costly and it negatively impacts the user perception of the product quality. Renesas’ DA16200 is the world’s first Wi-Fi SoC that enables 1+ year battery life for smart door locks solving one of the key technology hurdles for door lock makers.

Smart Home starts at the smart door. Doorbells are the gateway to a smarter and safer home. Smart doorbells combine technology and the traditional doorbell enabling a range of use cases such as motion detection-based notifications, automated recording of the video footage, and remote parcel delivery. Doorbells can connect with other smart home devices to provide control and convenience while making the home safer. Renesas’ Wi-Fi platform provides industry-leading battery life for battery-powered doorbell applications without compromising on the range and wireless signal quality.

Smart thermostats provide comfort to smart homeowners by adjusting the temperature intelligently while reducing the energy bill and environmental footprint. Renesas’ Wi-Fi products have been adopted by leading thermostat makers because of their long battery life, reliability, and range characteristics.

The vision of the smart home is coming together and home appliances are its integral part. Connected appliances such as air conditioners, refrigerators, washing machines, dishwashers, and dryers allow users to remotely check their status and control their operation. Connectivity allows devices to be more power-efficient and environmentally friendly. More advanced operations such as predictive maintenance can allow repairmen to come to customer premises even before the appliance failure. Refills for consumables e.g. dishwashing soap can be ordered automatically before the previous ones run out of stock. Renesas offers the most secure and reliable Wi-Fi products for home appliance makers. Our low power chips allow appliance makers to build energy-efficient appliances while our support teams ensure that customers get the support they need at each step in the product design and manufacturing process to create differentiated products.

Billions of wireless IoT sensors are expected to be deployed in the next few years. These everyday IoT sensors such as smart plugs and switches, garage door operators, smart lights, and fire/smoke detectors will become smarter through low-cost IoT technologies such as wireless transmitters and receivers. But transmitting and receiving data continuously is energy consuming and most IoT sensors will be battery operated. This interesting technology challenge is resolved by Renesas VirtualZero™ technology that enables low-cost, energy-efficient IoT sensors with multiple years of battery life depending on the application.
