MSP430FR5994: Power consumption MSP430™ low power MCU LaunchPad kits

Part Number: MSP430FR5994
Other Parts Discussed in Thread: MSP-EXP430FR5994

Hi team,

I'm looking forward to design a extension for MSP43x LauchPads. 

  1. Is it possible to run the programming circuitry on the LaunchPads via USB and the MCU from another source like a LDO seperatly?
  2. Whats the most effective way to compare the power consumption oft the CMSP43x family MCUs
  3. And the power consumption of the available LaunchPads

Kind regards

Dierk Bronner

    Hi Dierk,

    1. Please see Figure 6 of the MSP-EXP430FR5994 User's Guide, it is possible to power the 3.3 and 5V rails from the BoosterPack header connections: www.ti.com/.../slau678a.pdf
    2. Power consumption numbers for Active Modes and LPMs are given in each device's datasheet.
    3. LaunchPad power consumption is the same as that given in the datasheets, with the exception of the eZ-FET being connected which requires additional current. It is important that the MSP be initialized properly (correct unused pin connections, power control settings, pin direction/selection, etc.) to reflect numbers from the datasheet.

    Regards,
    Ryan
