What is the difference between the HALT and the STOP Modes ?

The HALT mode has the lowest power consumption mode (typ. 1ua) and it can be exited just by an external reset. Whereas the STOP mode can be exited by one of the 16 external WAKE-UP lines, resuming the code where it was stopped.

How much is the consumption in Stop Mode?

And how much is the consumption in ''Low Power Wait for Interrupt mode''? Can I periodically wake-up in this mode (with timers, not only with wake-up lines)?

Thanksssss

Stop Mode is only available with F124, F150 and F250 devices. Stop mode current consumption should be closed to Halt mode because both modes stop all clocks so CPU and peripherals.

Low Power WFI Mode current consumption is provided in the ST92F124/F150/F250 datasheet : 500uA typ, 800uA max at 4MHz/32

You can exit from this mode by an internal interrupt so yes you can periodically wake-up your ST9 using a timer

Check

http://www.stmcu.com/forums-cat-472-4.html

(see ST92F150 current consumption) for stop mode value.

You will notice that stop and halt current consumption are much different.

Take care,
