Other Parts Discussed in Thread: MSP430FR6989
Hi,
This is very urgent & important issue.
Customer built ultra low power system with MSP430.
They wanted to use MSP430FR6877. so TI provided MSP430FR6989 as a sample.
when they built a system with FR6989, in LPM3, the current consumption was 10uA.
However, When they used FR6877 on exact same board, the current consumption increased to 80uA.
It is right before MP, but this issue is too critical to start MP.
Is there any particular reason for this increased current consumption?
FR6989 is Rev E and FR6877 is Rev C. if they apply FR6877 Rev C, will this problem gone?
All other functions works fine but increased current consumption is the only problem.
Best Regards,
Ted
