Last Updated: February 03, 2011
Question: 

What is the FIT (Failure in Time) rate, or MTBF (Mean Time Before Failures) of the CY7C9689A?

Answer: 
The Failure In Time (FIT) number for the CY7C9689A device is 34 which is mentioned in the Qualification report.

The Mean Time Before Failure (MTBF) number is calculated as follows:

MTBF = 1,000,000,000 X 1/FR
where FR = Failure Rate

29,411,764 hours =1,000,000,000 X 1/34
