Dear all,

I am working with an LPC824 that sleep in power down mode. According to the datasheet the current should be 1.6uA typical 10uA maximum.
I have disabled BOD and watchdog oscillator, most IO are in output and set to 0 and few are in inputs with external high value pull-up resistor but all IO are in a valid, not floating, state.

I measure a consumption of around 30uA. Any idea how I can improve this ?

Any idea is welcome as I am going crasy !

PGR
