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.”

Hi, Alex. You mean hyperbus? I think Freescale is.

Junko, any idea whether some microcontroller manufacturer is designing mcu's with such interface ?

Hi Janine, 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.

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.

@Janine, I don't know. We need to check that out.

Hi, Janine. Not all, but one of the reasons is that it takes time for anyone to go through the qualification tests...at least that's what I heard from Spansion.

Oh, or are there more  test processes that he doesn't mention?

>>"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?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
