Power saving mode on ST7 lite

Posted on June 08, 2005 at 06:40

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.
