The CYW43012 from Infineon Technologies is an Ultra-Low Power Wi-Fi and Bluetooth Combo Solution for wearables, smart home products and portable audio applications. The solution is IEEE 802.11a/b/g/n-compliant and 802.11ac-Friendly, meaning it is interoperable with 802.11ac access points using standard modes. The chip simultaneously supports dual-band 2.4 and 5 GHz Wi-Fi and dual-mode Bluetooth/Bluetooth Low Energy (BLE) 5.0 applications. It prolongs battery life by leveraging 28nm process technology to cut power consumption up to 70 percent in receive mode and up to 80 percent in sleep mode. It is available in a 251-pin WLCSP package that measures 3.76 mm x 4.27 mm, 0.2 mm pitch and is ideal for IoT and embedded applications.
