Thermal noise in the analog circuitry is digitized to provide entropy for a true randomnumber generator (TRNG). The TRNG produces 16-bit uniformly distributed numbers. TheSoftware can use the TRNG to seed a pseudo random number generator (PNRG). TheTRNG is also used directly for cryptographic key generation.
Per the datasheet,
Random number generator
The STM32W108 micro controllers have a true random number generator. I cannot find any way to access this hardware feature. I do find a reference to stmRadioGetRandomNumbers in the simplemac-library.lib file, but not in the SimpleMAC library reference manual nor in the datasheet or Std Peripheral LIbrary code or programming manual. Is this a feature that is available for application use?
