    I have a boubt/problem with my project:

    I need to get my St7 Lite on power saving mode (only battery)

    but I need to wake up sometimes (0.5-1s) to check my

    probes.

    - Is possible to do?

    - If yes, How I can wake up my micro?

    with external interrupt (needs more component??)?

    or internal interrupt ??

    Is there any Application Note ?

    Many tanks in advantage!!

    Hi MBKS!

    ST7FLITE1x and ST7FLITE2x have an internal oscillator that can be used to wake-up the micro when it is in HALT mode.

    For ST7FLITE0x and ST7FLITESx, the AN1605 explains how to wake-up the micro by an external RC circuit.
