EFR32BG22 BLUETOOTH® 5.2 Wireless SoCs

Silicon Labs EFR32BG22 BLUETOOTH® 5.2 Wireless SoCs (System-on-Chip) are versatile, single-chip solutions for Bluetooth Low Energy (BLE), Bluetooth Mesh, and direction-finding, with sub-meter accuracy. The EFR32BG22 SoCs combine best-in-class, ultra-low transmit and receive power (3.6mA Tx at 0dBm, 2.6mA Rx) and a high-performance, low-power Arm® Cortex®-M33 core (27µA/MHz active, 1.2µA sleep). These devices deliver industry-leading energy-efficienc-extending coin cell battery life for up to ten years.
