I have a reel of MSP430FR4133IG56 56 pin controllers. They are all drawing about 0.3 ma while the same part I ordered directly from TI website is drawing about 7 uA. How do I figure out if I have a reel of faulty parts or Chinese Knock offs?

Hi Garret,
Is the configuration exactly the same? Same HW and same code?
300uA could be reasonable for LPM0, 7uA could be reasonable for LPM3 (does seem a little high). Regardless, please share a little more detail about what LPM state the device is in and any other resources that may be consuming power.
By chance is the debugger running? That will draw current.
Regards,
Evan
Ok thanks for the update. Post back if you need more support. If this thread auto locks (which can happen after extend inactivity) just open a new one and reference this one.
