15 June 1998 
 
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

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.
