What voltage is required for start-up in 1788?Sorry for the basic questions that I ask, because I am new.. :-[
Hello,
You should provide 3.3V ideally. But the microcontroller works in the 2.4V-3.6V range.
Of course, if the LPC1788 is mounted on a development board the whole supply for the board might be higher (part of the power supply might go to peripherals and/or board protection passive and active elements).
The best idea is to refer to the LPC1788 datasheet here: http://www.nxp.com/documents/data_sheet/LPC178X_7X.pdf (http://www.nxp.com/documents/data_sheet/LPC178X_7X.pdf).
