I don’t expect the total current to vary a lot from the datasheet typical numbers.</P><P></P><P>2.- It can't be accessed, if you attempt to write an address other than RAM using the "Write to RAM" command you will receive a SRC_ADDR_NOT_MAPPED return code.</P><P><BR />Hope it helps!</P><P></P><P>Best Regards,<BR />Carlos Mendoza<BR />Technical Support Engineer</P></BODY></HTML> Fri, 03 Feb 2017 00:06:15 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC1114FHN33-302-1-power-consumption-and-programming/m-p/652595#M25929 Carlos_Mendoza 2017-02-03T00:06:15Z
