Re: [lpc2000] Power at 60Mhz

At the risk of sounding like an idiot... (My apologies in advance)
 
Be sure that you are measuring just the CPU's power consumption and the board's.
 
Power supplies are not 100% efficient, particularly linear regulators.   Many of the
demo boards use a 1.8 volt linear regulator for the LPC21XX core voltage.  
 
I am interested in the final results of your measurements.

I'm trying to measure power consumption and I found out that the LPC2106 at 60Mhz uses 
~50mA. Is everybody seeing the same thing? I'm curious because the datasheet says 30mA 
at 60Mhz in an infinite loop (which what I'm doing). Thanks.
