Other Parts Discussed in Thread: MSP430WARE
Hello.
I'm trying to get the lowest possible current consumption in LPM3.
SLASE58B says, that maximum possible current in this mode could achieve 5.25 uA (the worst case). And a typical value is 1.16 uA.
I've took a LaunchPad and a standart example from MSPWare "MSP430Ware_3_70_00_05\examples\devices\MSP430FR2xx_4xx\MSP430FR231x_Code_Examples\C\msp430fr231x_LPM3_02.C"
After program was compiled and downloaded, I've detached all the pins of MCU from emulator and from external components(LEDs and LightSensor) on LaunchPad by removing jumpers.
By measuring current from external supply to LaunchPad (currentmeter was inserted in high side) I've got 17.3 uA.
What could be a reason of extra 16 uA of consumption? And how to get 1uA in LPM3 on LaunchPad?
Thank you for support.
