Hi!

What is the recommended capacitor for DVcc on MSP430F149? I cannot find it in the datasheet.

Best Regards

Hi Kalle!

Look at the following picture from the User's Guide (page 360):

Thanks! Is there also a minimum capacitor recommendation? It's for ATEX so we need to minimize all capacitors.

A minimum of 0.1µ should definitely be connected to each supply pin. It depends on your application and your design if this is sufficient, but I would stick to the recommendation. Of course no need to add the 10µ to each pin if there is another larger cap close to the supply pins.
