MSP430FR2433: LPM mode power consumption

Part Number: MSP430FR2433

Hi All,

If I have two MSP430 operating in same LPM mode but with different GPIO configuration (i.e. one has all GPIO output low while another has all GPIO output high), will the power consumption for two MSP430 be the same or will one be higher than the other in LPM mode? Thank you

    Hi Yifan

    If all GPIO is unused /no function in system, unused I/O pins should be configured as I/O function, output direction, and left unconnected on the PCB.
    Alternatively, the integrated pullup or pulldown resistor can be enabled by setting the PxREN bit of the unused pin to prevent a floating input. from this point of view, these 2 low power mode MCUs should have the similar consumption.

    if there are some GPIO is used driving some device, there is the current on the GPIO, these 2 MCUs should have the different power consumption.
