CC2640R2F: TRNG generator use case

Part Number: CC2640R2F

Champs,

Customer would like to use the device as a true random number generator only, no need for radio. I am looking for HW application advice how to disable all radio functionality and leave only the MCU core and and serial peripherals running. 

thanks

Michael

    If you don't need the radio you can leave the RF_P and RF_N pins not connected. The 24 MHz stal can also be omitted since the chip runs from the internal RF oscillator when the RF is not in use.

    From the software side you don't have to do something special since the RF modules will be off if you are not using the RF driver.
