Hello,
I am using Analog Devices ADuC836 micro-controller. As per my application total current consumption of all module of micro-controller must not exceed 2.5 mA. I am using inbuilt 16 bi Delta Sigma ADC, 12 bit DAC, external refernce (2.5V) for ADC, Clock frequency approx. 3MHz.
I've gone through the datasheet, but didn't found anything how to lower power consumption... Uunused pins should be connected thus (pullup / pulldown / floating / configure as input or out put).....
Can anyone point me to an application note or other info that could help? If I don't find any more info I'll simply connect the unused pins to ground...
Thanks.
To minimize power consumption: traditional port pins (Quasi-bidirectional) should be left in the reset state (high) non-traditional port pins should if possible be configured open collector and written low if not possible port pins should be configured Quasi-bidirectional and left in the reset state (high)
also, have you considered sleep mode
