XILINX FIRST QUARTER FY05 REVENUES INCREASE 5% SEQUENTIALLY

SAN JOSE, CA, JULY 22, 2004 — Xilinx, Inc. (Nasdaq: XLNX) today announced revenues of $424 million in the first quarter of fiscal 2005, a sequential increase of 5% from the prior quarter and an increase of 35% from the same quarter a year ago.  Net income was $95.3 million or $0.26 per diluted share including a $7.2 million pre-tax charge associated with the acquisition of Hier Design in June 2004.  Net income was down 27% from $130.9 million, or $0.36 in the prior quarter, which was positively impacted by a $34.4 million reduction in taxes associated with an IRS settlement and also included a $7.0 million pre-tax charge in connection with the acquisition of Triscend Corporation.

Xilinx also announced today that the company’s Board of Directors declared a quarterly cash dividend of $0.05 per outstanding share of common stock, payable on September 1, 2004 to all stockholders of record at the close of business on August 18, 2004.

Additional fiscal first quarter comparisons are represented in the chart below.

Gross margin for the quarter increased for the sixth consecutive quarter to 66.0%, up from 64.7% in the prior quarter and up from 60.1% in the same quarter a year ago.  This was the highest gross margin the Company has reported in 15 years.  Better than expected yields and product mix contributed to the increase in gross margin.  Average selling prices remained firm.

“Sales from all geographies were up sequentially in the June quarter,” said Wim Roelandts, Xilinx’s chairman and chief executive officer.  “New products grew a healthy 10% sequentially and have nearly doubled versus the same quarter of the prior year.  Virtex-II Pro™ sales were the largest contributor to this sequential increase as design wins are beginning to turn to meaningful production volumes.  Additionally, sales from the Spartan-3™ family, which is the industry’s first FPGA manufactured using 90-nanometer (nm) process technology doubled sequentially during the quarter.”

Standard & Poor’s Ratings Services recently upgraded Xilinx’s corporate credit rating to investment grade, reflecting the Company’s leading market position in programmable logic, good cash flow generating capability, and an increasingly diversified base of customers and end markets.  Xilinx is the only PLD Company to have attained this rating.
