HSINCHU, TAIWAN AND CARLSBAD, Calif. - July 10, 2007 - UMC [(NYSE: UMC; TWSE: 2303)] and MaxLinear, Inc., a technology leader at the forefront of developing fully integrated broadband radio frequency (RF) systems-on-a-chip for worldwide television standards, today announced that MaxLinear produced its breakthrough silicon tuner IC, the MxL7001 on UMC's CMOS process. The MxL7001 is the world's smallest silicon tuner produced to date for mobile TV applications such as digital TV (ISDB-T) on cell phones.

"This successful cooperation between UMC and MaxLinear has resulted in a technology that is poised to provide consumers with high-quality digital TV on mobile applications, without interfering with the size, power or performance of end appliances," said Henry Liu, senior vice president of UMC's New Business Development Division. "Our most recent fabrication alliance with MaxLinear follows a series of other similar successful product developments for them, including MaxLinear's Silicon Tuner for fixed and portable television applications that is currently in volume production at UMC."

"We are very excited about our cooperation with UMC as we were able to produce the MxL7001on CMOS rather than in SiGe, an industry breakthrough," noted Kishore Seendripu, MaxLinear's CEO and president. "UMC has continued to show us over and over again that it has the process technology, the people and the support to help us deliver leading products to market. We are looking forward to continuing our collaboration as we head toward volume production of the MxL7001, and toward cooperating on a myriad of other exciting technology developments."

The MxL7001 is a 1.9mm x 1.9mm single-die, digital CMOS IC that is at the foundation of a family of MaxLinear products supporting mobile TV standards worldwide. The device is 1/10th the packaged area of MaxLinear's MxL5000-family ICs (6mm x 6mm) which set the previous record for small size, low power, and superior performance. The MxL5000 ICs will continue to be a part of MaxLinear's standard offering for fixed and portable television tuner applications. Using a standard digital CMOS process technology, the MxL7001 consumes only 65mW of power, reducing battery draw and minimizing heat dissipation -- two very important criteria for mobile TV applications. The highly integrated MxL7001 supports both ISDB-T 1-segment and 3-segment applications. MxL7001 eliminates the need for an external balun, SAW filters and IF amplifier, which reduces both board footprint and BOM costs.
