This chip is done in a 90nm technology, at 200MHz the chip will get warm.</P><P>Depending on the number of peripherals you run, it also might get hot.</P><P>What you should check: &nbsp;the clock tree for all peripherals is enabled by default after reset. So you should switch off everything in the beginning (except the core of course :-) and then switch the clocks for the needed peripheral blocks on step by step in your system initialization.</P></BODY></HTML> Thu, 21 Sep 2017 09:11:04 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC4337-running-at-200MHz-45-degrees-C-Is-this-normal/m-p/709220#M28607 bernhardfink 2017-09-21T09:11:04Z Re: LPC4337 running at 200MHz, 45 degrees C.
