There's no simple value (in ohms) for an active pull-up.</SPAN></BODY></HTML> Wed, 15 Jun 2016 19:41:24 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC1114-pull-up-down-resistors-value/m-p/538332#M11654 lpcware 2016-06-15T19:41:24Z Re: LPC1114 pull up/down resistors value? https://community.nxp.com/t5/LPC-Microcontrollers/LPC1114-pull-up-down-resistors-value/m-p/538333#M11655 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by nxpsupport on Fri Nov 09 16:16:06 MST 2012</STRONG><BR /><SPAN>The pull-up and pull-downs are not actual resistors. They are transistors configured as a current source. These are "weak" current sources. For simplicity we call it a resistors.</SPAN></BODY></HTML> Wed, 15 Jun 2016 19:41:25 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC1114-pull-up-down-resistors-value/m-p/538333#M11655 lpcware 2016-06-15T19:41:25Z
