Hi,
My name is Mayur.
I am new to PIC micro. I am using the PIC18F65K22 micro for low power application.
When i put the Micro in the sleep mode, it consumed 50uA, although the datasheet suggests it should not be using more than 700nA.
I have switched off RTCC, Watch Dog, Brown Out and kept all the port pins as inputs.
There is the pull up resistor with MCLR pin & Internal Regulator Enabled. Although to check the power consumption, I have supplied 2.0 volts for testing purposes.
In view of the testing, I have disconnected any and all the peripherals of my circuit board to ensure I am measuring the actual current consumption of the Micro.
Can anyone please help what else I can look at to reduce the power consumption of my micro in the sleep mode.
Just for the information, i have used one port pin as an output to monitor whether the micro is sleeping or working. If working, it oscillates and I can monitor it on scope. I am using INT0 to wake up the micro.
