Subject: Product Change Notification PCN99008 - A Change
to the Icc Standby Specification of XC1702L and XC1704L Products (all Packages)
Change Description: Increase in Icc Standby from 50 µA
to 350 µA
Products Affected: All XC1702L and XC1704L Product in
all packages.
Reason For Change: Xilinx is addressing a TCE
speed issue that occurs only under the following conditions:
| 1. |
XC1702L or XC1704L is used as the second or subsequent part in a cascaded
chain |
| 2. |
And the configuration speed is 7.5 MHz or higher |
| 3. |
And the first bit of the second or subsequent part in the cascaded
chain is programmed to a zero. |
The solution to this speed problem necessitated a circuit design change,
which increased the Icc standby current.
Key Dates: Xilinx has evaluation quantities of this product
available today. Standard production utilizing the new design will start
shipping on 1 January 2000. This change will not affect the electronic
ID of the part and will not require an update of your programming algorithm.
Traceability: All products shipped with a year 2000 date
code or later will be of the new design.
Response: No response to this notification is required.
Requests for additional data or support should be made within 90 days of
