MSP430G2333: Need technical information on low power modes

Part Number: MSP430G2333

Hi Team,

I need detailed information about various low power modes. Complete list functions which operate and doesn't operate during those power modes. 

Regards

Safir

    Hi Safir,

    Please see section 6.3 of the device's datasheet, which lists the clocks that are disabled in each low power mode (LPM). There is no list of which functions or modules operate in each of those modes because each module can be driven by different clocks. You can use this list along with the User's Guide for the family of devices to determine which modules you can use in each LPM and what clocks you can use to drive those modules.

    Regards,

    Thanks.

    May I know the operations that can be performed using ACLK. For example WDT, Brown out, Timer, ADC etc. Also LPM3 uses ACLK and consumes 0.7uA typical current. Does this current increases if we use Timer and ADC in LPM3. Also suggest a interrupt pin in controller to wake up the controller from LPM3 to Active mode.

    Regards

    Hi Safir,

    as Nathan already mentioned please check the User's Guide (www.ti.com/lit/slau144) to check which peripheral can use which clock.

    WDT = SMCLK, ACLK
    Brownout = no clock necessary, voltage dependent
    Timer = ACLK, SMCLK, external clock
    ADC = MCLK, SMCLK, ACLK

    The current consumption increases slightly in LPM3 if you use the timer, as digital logic is clocking. If you use the ADC it will increase even more, as the conversion logic is clocking. See table 5.29 the current for ADC10 is specified to be I(ADC10)~600uA.

    Best regards,
    Andre
