PSoC 5LP Consumption in Hibernate
I'm trying to measure the consumption for the PSoC 5LP (to be precise, CY8C5868LTI-LP039) device.
Currently I'm just measuring power consumption with nothing in the schematics, but I change the operating modes (I cover all the modes possible).
All other modes seems fine (even Sleep mode comes close to what the datasheets say, ~2 µA), except for the Hibernate mode, which somehow consumes ~45µA (well, that's what came up on the DMM screen).
My current setup is using a DMM set to DC ammeter connected in series with the PSoC VDD (Digital, Analog and IO pins are tied together). The wirings and connections all follow the guidelines given by the documentations.
Could this be a problem with wakeup? Currently all IO pins are not connected to anything. I didn't restore the clocks either after CyPmHibernate() since I thought that the device would hibernate forever. Maybe that isn't the case.
