BG2B is the lowest-power Bluetooth LE SoC from Silicon Labs so far

Silicon Labs BG2B is an ultra-low-power Arm Cortex-M33 Bluetooth 6 LE SoC with support for Channel Sounding, “Secure Vault High” security, and integrated CAN-FD and peripherals such as LED drivers and ADCs for smaller, longer-lasting IoT devices. The company claims it’s the lowest-power Bluetooth LE device in its portfolio, with 1.1 µA EM2 sleep current with RAM retention, as well as 14%-15% lower MCU active current and lower Bluetooth receive current compared to Silicon Labs BG22/BG22L. The new microcontroller targets…
