I'm constructing a circuit for outdoor use. I was thinking about using a resonator to save space vs. a crystal/capacitor combo.
Any advantages or disadvantages I need to consider?

Hi Dynamo,
If there are no critical time issues ... no problem. just have a look at tempco and freq. precision to see what.

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

A resonator is good for the above and should save you a couple of capacitors if you select one with internal caps.
I had two thoughts while laying out the board, save on space AND I believe a resonator is better when there are going to be temperature extremes. Correct?

Crystals Are Better For Initial Calibration Accuracy And Temperature Stability.
Resonators Are Typically 0.3% Accurate And 0.1% Temperature Stability, While Crystals Are 0.005% On Both Accounts. In Most Applications, The Resonator Is Adequate However.
I Have One Project That Has Timers Running Up To 24 Hour Range And Temperature Exposure Of 0-90 Degrees Farenheit And Used A Crystal For Stability.
Most Projects I Design Are Ok With The Internal Rc Clock.
