MSP430F5249: Power consumption in LPM0/1

Koichiro Tashiro

Hi

My customer is interested in F5249 and asking question.

Q) What is power consumption in LPM0 and LPM1 with SMCLK=1kHz?
Data Sheet[slas897A] shows only LPM0 with SMCLK=1MHz.

Thanks and regards,

Hi KoT,

What is the clock source for SMCLK in 1kHz?

Normally, the power consumption of 1kHz should be less than 1MHz. But you need to test in the specific condition of your application because we can't test all of the conditions with different clock&power configurations.

Hi Wei,

There was a mistake in previous question. Customer actually wants to know SMCLK 1MHz (clocked from DCO).
Datasheet shows LPM0 with this configuration.
What is the rough estimation for LPM1 ?

Thanks and regards,
KoT
