EFR32MG 2.4 GHz 19.5 dBm Radio Board
BRD4154A Reference Manual
The EFR32MG family of Wireless SoCs deliver a high perform-
ance, low energy wireless solution integrated into a small form
factor package.
By combining a high performance 2.4 GHz RF transceiver with an energy efficient 32-bit
MCU, the family provides designers the ultimate in flexibility with a family of pin-compati-
ble devices that scale from 128/256 kB of flash and 16/32 kB of RAM. The ultra-low
power operating modes and fast wake-up times of the Silicon Labs energy friendly 32-
bit MCUs, combined with the low transmit and receive power consumption of the 2.4
GHz radio, result in a solution optimized for battery powered applications.
