Hi,
documentation says "VDDIO1 voltage must be above 2.2V to allow the chip to start-up (POR threshold)".
but I need to work with a 1.8V power supply for power consomption.
component doesn't start with a 1.8V supply (as said in doc) at first power up, then next restart are ok.
when component doesn't start it consumes more than 50mA !!!
How can I work ? which schematic do I need ?
Thanks
