PSoC 5, 3 & 1 MCU

I have a project where I'm trying find sources of unexpected power consumption on the board.  I want to make sure that I know how much power is being consumed by the PSoC and how much is being consumed by other components.  If I erase the flash on a PSoC 5LP, is it reasonable to assume that its power draw would be 0 (or, say, less than 1mA)?

Emmm...Erasing its Flash may not draw its power consumption less than 1mA...(I'm not very sure, I don't have a tiny kit to test its current).

But you may try "CyPmHibernate()" or "CyPmSleep()" in main.c, setting its put the device into low power mode.

For more details, refer: https://www.cypress.com/documentation/application-notes/an77900-psoc-3-and-psoc-5lp-low-power-modes-...

Thanks,
