So a 1 uF becomes 0.5 uF, then use two or just get a 2.2 uF cap. What is relevant for decoupling is that there are some caps present to short spikes on the supplies. The actual value of the capacitors is not so relevant. The "golden rule" for supply decoupling is that there should be a cap close to each supply pin on all ICs. If you want add extra caps, feel free to do so. If you follow this rule then you did what is needed and your design should be OK. | |

To cite this article: "eramic capacitors are DC voltage sensitive, [...] And the ones with high capacity in a very small package are often the worst" | |
