The BG22 Series from Silicon Labs are Bluetooth low energy (BLE) wireless SoC solutions that are part of the Wireless Gecko Series 2 platform. These SoCs are ideal for enabling user-friendly Bluetooth 5.2 networking for high-volume IoT products. By combining ultra-low transmit and receive power (4.1 mA TX at 0 dBm, 3.6 mA RX) and a high-performance, low-power Arm® Cortex®-M33 core with 76.8 MHz maximum operating frequency, they deliver industry-leading energy efficiency and can operate on a coin cell battery for up to ten years. The SoCs include up to 512 kB of flash and 32 kB of RAM and feature Bluetooth 5.2 direction finding that targets a wide range of indoor positioning, navigation, and asset and people tracking applications.
The BG22 Series provides access to several technologies designed to protect the product, including Secure Boot with Root of Trust, Secure Loader and Secure Debug. Applications for these SoCs include Bluetooth mesh low-power nodes, smart door locks, personal healthcare, and fitness devices. Asset tracking tags, beacons and indoor navigation also benefit from the SoCs' versatile Bluetooth Angle of Arrival (AoA) and Angle of Departure (AoD) capabilities and sub-one-meter location accuracy.
