Is Low MCLR brings the PIC into a very deep sleep?

[Yves]

Hello All,

I know bringing MCLR low reset the PIC but my question is: anyone knows if the PICs still drawing some stray microamps current?

Cheers,

The MCLR input leakage + Pull up resistor + power down current. For specific values, check the corresponding datasheet.

Edit: Oops my bad, I thought you wanted info on MCLR during deep sleep.

Now reading carefully what you actually asked - bringing the MCLR pin low, does not bring the device in low power state but in reset state. In reset state the oscillator is still running. It will only reset the program vector and some of the SFR.

Many thanks for your reply Trastikata.

MCLR will reset the PIC if it is enabled, otherwise it is an input. As an input you might be able to use it in code to sleep the PIC.
