EFR32MG13 Mighty Gecko Multi-Protocol Wireless SoC Family Data Sheet
System Overview
3.2.10 Radio Controller (RAC)
The Radio Controller controls the top level state of the radio subsystem in the EFR32MG13. It performs the following tasks:
• Precisely-timed control of enabling and disabling of the receiver and transmitter circuitry
• Run-time calibration of receiver, transmitter and frequency synthesizer
• Detailed frame transmission timing, including optional LBT or CSMA-CA
3.2.11 Random Number Generator
The Frame Controller (FRC) implements a random number generator that uses entropy gathered from noise in the RF receive chain.
The data is suitable for use in cryptographic applications.
Output from the random number generator can be used either directly or as a seed or entropy source for software-based random num-
ber generator algorithms such as Fortuna.
