Or in other words: Assuming that a stable power source is attached, how long does it take until the chip executes the first user instruction after the power source is attached? I couldn't find anything in the datasheet about that, just that the flash wake-up timer generates a 100uS startup time and then 250 additional clock cycles are needed. As the user program is stored in the flash, the startup time is higher than 100uS + 250 clock cycles I assume?</P></BODY></HTML> Mon, 13 Jul 2020 18:29:42 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC1765-Startup-time/m-p/1094250#M41924 flole 2020-07-13T18:29:42Z Re: LPC1765 Startup time? https://community.nxp.com/t5/LPC-Microcontrollers/LPC1765-Startup-time/m-p/1094251#M41925 <HTML><HEAD></HEAD><BODY><P>Hi, Florian,</P><P>Pls refer to the following table, copied from UM10360.pdf.</P><P>It describes the time from rising Rest signal to the instant that the user code is executed.</P><P>Hope it can help you</P><P>BR</P><P>XiangJun Rong</P><P><span class="lia-inline-image-display-wrapper" image-alt="pastedImage_1.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/115717i65C0D3A62E271C2C/image-size/large?v=v2&amp;px=999" role="button" title="pastedImage_1.png" alt="pastedImage_1.png" /></span></P></BODY></HTML> Tue, 14 Jul 2020 05:48:37 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC1765-Startup-time/m-p/1094251#M41925 xiangjun_rong 2020-07-14T05:48:37Z
