Tool/software:
Hi,
The customer has a problem on the MSP430F5310IRGCR in their products which have been already released into the market.
Could you help to solve the issue below ?
In their system, GPIO (Pin 18) outputs High when the input voltage into ADC (Pin 4) exceeds the certain set value as overvoltage.
However, out of 500K units shipped, they found the issue of abnormal output in 10 units.
On some device, the output is stuck to HIGH and never changed even though the input voltage become low.
On other device, the output is not toggled to HIGH or LOW correctly.
- During the issue occurred, MSP430 didn’t show any error and the other IOs continue to work correctly.
- The output on GPIO (Pin 18) is recovered from this failure by reset (RST on Pin 64).
- These issues occurred on the room temp.
- The 10 units mentioned above are Revision F device.
Do you have any idea to solve this issue ?
Thanks and regards,
Hideaki
