For product A (68-pin VFQFN package), pins 31 and 66 are VCAP pins, and 2.2uF capacitors have been placed on each pin. Should pins 33 and 66 be connected to each other, or is it sufficient to place the capacitors on each pin individually?
Hello
As you can see on the AN5711,
« It is recommended to connect the two VCAP pins together. If there are two VCAP pins (such as for the LQFP64 package), each pin must be connected to a 2.2uF (typical) capacitor (for a total approximately 4.4 F) »
Best Regards.
