MSP430FR2111: AVCC input available

Lisa Ding

Hi Champs,

I checked MSP430FR2111 datasheet and user guide. I didn't find AVCC pin and information on datasheet. In FR2111, ADC module input power is DVCC not AVCC. Customer asked about ADC ref setting which related with AVCC. They don't know what AVCC level and resource. Could you please tell me does AVCC is connected with DVCC internal ? If yes, ref setting AVCC level should be the same as DVCC ? thanks for your reply in advance!

Hi Lisa!

When there is no dedicated AVcc pin available, all analog circuitry is also sourced by DVcc. And DVss is AVss.

Hi Lisa,
as Dennis mentioned already, there is only one power pair available on this device. It supplies both, digital and analog modules.

Best regards,
Tobias
