LPC812 Current Consumption

Hi,

 

I am trying to replicate the current/power measurements of the LPC812 board. I have downloaded the AN11561 application note and source code from NXP and I downloaded the code for low power modes on my board.

 

However, I am getting ~3.2mA current consumption when in active mode and ~1.1mA when in sleep mode which is far off from the expected values. According to AN11561 and the datasheet of my microcontroller I would expect to see ~1mA when in active mode and ~0.7mA when in sleep mode.

 

Any suggestions on the cause behind the difference between the measured and the theoretical value?

 

Thanks in advance,
Theo
