STM32F103RDT6 VDDA PIN

[Mom.1]

Hi,

In the STM32F103RDT6 , The datsheet showing VDDA pin needs 10nf AND 1Uf. But in AN2586 reference document, it shows 100nf and 1Uf. which one is correct?

Warm regards,

The particular value of 10nF/100nF is not that important. Routing, layout of ground, and placement (as close as possible) of the ceramic capacitors in supply is more important that their particular value.
