Attention: Valued Customer,

Subject: Product Discontinuation Notice (PDN98001). Discontinuation of the MQFP (Metal Quad Flat Pack) package option for the products listed below.

Products Affected:

XC4008-6MQ208C/I XC4008-5MQ208C/I XC4008-4MQ208C

XC4010-6MQ208C/I XC4010-5MQ208C/I XC4010-4MQ208C

XC4025-6MQ240C/I XC4025-5MQ240C/I XC4025-4MQ240C

Change Description: The above part/package combinations are being discontinued.

Reason For Change: The MQFP (Metal Quad Flat Pack) package was originally introduced by Xilinx at the time of the release of certain XC4000 products. This package offered better thermal resistance than the then available PQFP (Plastic Quad Flat Pack) options. Since that time Xilinx has made these same parts available in the HQFP (thermally enhanced Quad Flat Pack) package. The HQFP package offers better thermal resistance (see table below) than the MQFP package, while offering a footprint that is fully compatible.

Theta _JA (°C/watt)

MQFP208 MQFP240 17.5 - 18.4 16.4 - 16.8

HQFP208 HQFP240 13.5 - 14.8 11.8 - 12.7

Key Dates: Last date to order any of the above products is 15 June 1999 with final delivery on or before 15 September 1999.
