Hello,

I am experiencing a high amount of what is a suspected "lock up" condition with the S29GL101GS flash part.  When commanding an erase, seems like the flash took the command, per ISE iMPACT, but it just sits, never completing the operation.  This is on a large batch of parts.  Configuration in the ISE iMPACT tool has been verified as correct, as other S29GL101GS parts work without issue.  Unfortunately I don't have the lot/date info on the passing parts. 

I believe the lot/date code is : "744BB053 C"

Is there a possible issue with the above lot/date code?

Thank you,

Lee G.

Hello,

Could you please provide more details about how you are testing and observing this failure?

How many devices are showing this failure? Are you observing this issue with all of the devices with lot code "744BB053 C"?

Thanks and Regards,

Hi Sudheesh,

In regards to how we are testing and observing this failure, we are simply, within ISE iMPACT, attempting to send a sector erase command prior to programming, and get no response from the device, causing the GUI to hang. We tried a simple program, same issue, no response from the device, GUI hangs. It is only occurring with this device, and so far, only the date/lot code below.

So far, I believe we have seen this on about 20 devices, with a possibility of more in the short term.

Thanks,

Lee G.

Yes I will, but I really need an answer ASAP. Production is affected at this time, and I have been waiting more than a week for a SIMPLE answer!
