Other Parts Discussed in Thread: MSP430F427A

The current consumption of watchdog mudules is not in MSP430F427A datasheet.

And I want to know current consumption when each peripherals are actived.

How much is the current consumed by each peripherals of MSP430F427A?

    Hello Remony,

    We don't spec any power numbers for each module (timers, communication, etc.) mainly because they are very low power numbers and the power they do consume is included in the Active Mode and the LPMx current spec. Keep in mind however that when the digital peripheral is on it is typically using a clock source which consumes power. Depending on the module you can configure the clock source and the module can remain enabled or disabled depending on your LPM mode and settings. For the MSP430F427A the WDT+ sources can either be SMCLK or ACLK. If you use ACLK as the source for the WDT+ it will remain enabled up to LPM3 but if you use SMCLK as the source it can get disabled by anything higher than LPM1.

    Regards,
    Ryan
