System Overview
3. System Overview
3.1 Introduction
The EFR32 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 systems 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 block diagram of the EFR32MG12 family is shown in
Figure 3.1 Detailed EFR32MG12 Block Diagram on page 4.
The diagram
shows a superset of features available on the family, which vary by OPN. For more information about specific device features, consult

Internal
Reference
Op-Amp
The 2.4 GHz antenna interface consists of two pins (2G4RF_IOP and 2G4RF_ION) that interface directly to the on-chip BALUN. The
2G4RF_ION pin should be grounded externally.
The external components and power supply connections for the antenna interface typical applications are shown in the RF Matching
Networks section.
