Hi,

can somebody give me a value for the Power Consumption of a LPC4370.
My code using M4 and M0 core.
In M0 --> gpio,adc(12bit)@40Mhz,dma
In M4 --> FFT processing

Thanks & Regards,
Jinesh

For information see the data sheet "10.1 Power Consumption".

To measure it on an LPC-Link2, study the schematics from Embedded Artists:
http://www.embeddedartists.com/products/lpcxpresso/lpclink2.php
http://www.embeddedartists.com/sites/default/files/support/xpr/link2/LPC-Link-II_Rev_C.pdf

It seems you can remove R53 (0R) and add JP3, and then measure the complete 3.3V supply current via JP3.
Note that it supplies all parts on the board, not jut the LPC4370.

How are we suppose to know? Are you an engineer or a management person?
