CC2640: ADC Input

Dan Cristy

Part Number: CC2640

Hi Team –

It looks like there are 8 pins that can definitely be used for ADC inputs. I believe we'll need a 24MHz external osc to use Bluetooth, not the 32 KHz. Therefore, I believe that we can use those two IO pins to get to 10. Is that correct?

Thanks!

What do you mean "I believe that we can use those two IO pins to get to 10?"

Hello,

No, the X32K_Q1 and X32K_Q2 pins can only be used for a external crystal, so you will only get 8 ADC pins. You can use Bluetooth with only a 24 MHz crystal, but you will achieve better power consumption with an external 32 kHz crystal.

Best regards,
Simon
