CC2642R: Peak power consumption

I suppose you can estimate this by adding Active-ModeTX 5 dBm:9.6 mA and Active-Mode MCU 48 MHz(CoreMark):3.4 mA (71μA/MHz) so it's about 13mA on CC2642R itself. If you have IO pins to cause extra power consumption in your application, you have added those extra power consumption by yourself.
