Part Number:CC3220SF-LAUNCHXL
Hi,
I'm doing some measurements on the CC3220SF Launchpad Hardware, when using the on-board USB power and following the swru463a.pdf documentation, I have a consumption of 140µA in idle, which is correct regarding the CC3220SF datasheet (MCU and NWP in LPDS).
However, when I switch to an external power supply at 3.3V following the section 2.5.3 of swru463a.pdf, I measure a consumption of 21mA when in idle.
In the datasheet, a consumption of about 20mA would match a MCU in active mode and a NWP in idle connected mode, so why is it doing this ?
I'm running the exact same software when measuring the consumption on the Launchpad, is there anything else I have to do in order for my MCU to go in LPDS mode ?
