Bluetooth device shipments are forecast to grow 26 percent by 2023 (from 4 billion units in 2019 to 5.4 billion units). Silicon Labs designed the EFR32BG22 (BG22) SoCs to meet the unique requirements of high-volume, battery-powered Bluetooth products. Featuring an ultra-low transmit and receive power (3.6 mA TX at 0 dBm, 2.6 mA RX) and a high-performance, low-power M33 core (27 µA/MHz active, 1.2 µA sleep) – BG22 delivers industry-leading energy efficiency that can extend coin cell battery life beyond five years.
BG22 Bluetooth Soc

EFR32BG22 Series 2 Bluetooth® Wireless SoC

EFR32BG22 (BG22) Bluetooth low energy (LE) wireless SoC solutions are part of the Wireless Gecko Series 2 platform. The BG22 family's combination of best-in-class 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 (27 µA/MHz active, 1.2 µA sleep) delivers industry-leading energy efficiency that can extend coin cell battery life up to ten years. Target applications 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.
