They're both single supply 3.3V chips. The NXP only needs five-size passive support components. > here the schema : https://file.tsaitgaist.info/www/?a=d&i=CWn6xIaCVe I get nonsense messages visiting that page. :\ "needs input" something or other. Maybe you can attach them to the wiki? Christian Vogel wrote: > according to the datasheet VDDPLL powers the oscillator, you should > not leave it unconnected.
