3.1 Introduction
The BGM113 product family combines an energy-friendly MCU with a highly integrated radio transceiver. The devices are well suited
for any battery operated application, as well as other system requiring high performance and low-energy consumption. This section
gives a short introduction to the full radio and MCU system. The detailed functional description can be found in the EFR32 Reference
Manual.
A detailed block diagram of the EFR32BG SoC is shown in the figure below which is used in the BGM113 Bluetooth Smart module.
