Subject: Process Change Notification (PCN95005) "An Evolutionary Change in the Xilinx XC7000 Fabrication Process"
Products Affected: XC7236A, XC727A, XC7354, and XC73108 (All packages and speed grades)
Change Description: Fabrication process migration from the 1.0µM UVCMOS EPROM process at tsmc to the 0.85µ process at this same facility.
Product Change: The products mentioned above will be moved to the 0.85µM UVCMOS EPROM process at tsmc. The 0.85µM devices are 100% pin and function compliant with the 1.0µM devices. Product manufactured with the 0.85µM process can be identified by the marking "xxK" which is appended to the date code (1.0µM product bears the identifier "xxH")
Reason For Change: The foundry is migrating production from the 1.0µM process to the 0.85µM process to enhance product availability. This also permits the introduction (by Xilinx) of higher speed grades (notably the XC7354-7, the XC73108-10, and the XC73108-7).
Key Dates: Qualification of this product in the evolutionary process has been completed and is attached. Production has started in the 0.85µM process. Product availability is immediate.
Response: No response to this notification is required. Requests for additional data or support should be made within 90 days of notification. Please address any questions you may via email to "pcn@xilinx.com" or directly by fax at 408 559 1368.
