Tool/software:

Hi team, 

could you help to check what value is the minimum capacitor on VDD pin, from the datasheet, I see the value is 0.1uF. if we can use <0.1uF capacitor?

    A low-impedance connection (i.e., short traces, and a small capacitor packate) is more important than the absolute value. It is likely that 10 nF works as well as 100 nF. In practice, you would use the same value as used elsewhere on the board to simplify the BOM.
