>>"There are others who also claim a similar extended high temperature, but typically, they have not passed all the qualification processes like ours did.">> Is that because they couldn't pass or because they haven't been tested in both of the qual processes mentioned?
Thanks @Junko. It would also be interesting to know if the OEMs require the qual tests or just prefer them for these parts. That will probably determine if the other manufacturers will go through the cost/effort of the process.
Although some suppliers claim 125C degree operation, they typically follow JEDEC standards to meet general market needs. However, for automotive the qualification is more stringent and must adhere to the Automotive Electronics Council (AEC) qualification specification, called AEC-Q100. Spansion is an active member of the AEC. Any products that we deem automotive grade have to pass the AEC-Q100 qualification process as well as our GT-grade test flow that ensures less than 10 DPPM, but targets zero failures.
The Spansion HyperBus Interface is being implemented broadly by leading system-on-chip manufacturers. From our press release “The Spansion HyperBus Interface is being implemented broadly by leading system-on-chip (SoC) manufacturers. Freescale is the first company to announce their support. You'll see a number of their Microcontrollers appearing in the near future taking advantage of this new interface.”
