Part Number: TDA3
Hello,
A customer has observed a failure related to TDA3, the SPI interface and a Cold Temperature condition (~ -35C).
On the customer board, the TDA3x SPI is configured as a Master.
- At room temperature testing, the customer observes a valid clock signal as well as valid SPI signals. The target board operates as expected.
- At cold temperature (~ -35C), the customer does not observe a valid clock signal or expected SPI traffic. The target board does not operate.
What register configurations should be checked in this error case?
Which debug logs might capture a failure event?
What is the relationship between temperature and SPI, if any?
The device under test is a prototype TDA3x device that has been full-temp tested.
The customer has not observed failure across multiple target boards; the customer observed this on a single target board.
What other meaningful information should I request from the customer?
Thank you!
