Dear all,
We seem to be unable to lower the power consumption to the level indicated in the datasheet (~2 uA).
The MCU is programmed to turn off all peripherals and timers (which should be off anyway after boot), and to set all pins to low output. When that's done, LPM3 is entered. Here's a link to the code:
When this code is executed on the TI MSP-TS430PN80A board, the power consumption is ~70 uA. On our own board, the consumption is ~95 uA. The theoretical consumption of our board should be ~25 uA, which seems wrt the consumption of the TI board.
All of this seems to indicate that the power consumption of the MCU is around 70 uA, which is way higher than the announced 2 uA. Is there something wrong in the way we handle LPM3?
Thanks in advance for any help.
