Infineon Technologies AG announced that its 512Mb GDDR3 (Graphic Double-Data-Rate 3) graphics DRAM was selected by ATI Technologies for use with its graphics processor drives ASUS A7G notebook" target=_blank>Mobility Radeon X1600 graphics processor targeting notebook PCs.

According to the press release, the Mobility Radeon X1600 is ATI's new mobile graphics processor designed to deliver stunning visuals and lightening-fast graphics for the performance thin notebook segment, answering the trend for increased mobility and life-like visuals in a high-performance design.

"The GDDR3 memory will enable the Mobility Radeon X1600 to deliver lightning-fast visual performance with superior power management capabilities," said Phil Eisler, VP and GM of ATI's Mobile Business Unit. "By working closely with industry-leading companies like Infineon, we are able to bring a new era of performance-per-watt efficiency with our mobile graphics products to our customers."

Infineon's 512Mb GDDR3 graphics DRAM for high-performance mobile and desktop 3D graphics applications supports clock frequencies of up to 800MHz and uses a 32-bit interface. It is capable of handling data bandwidths of up to 1.6Gbps per pin. In addition Infineon's power saving trench technology offers less power consumption than other DRAMs at a given performance and improves battery lifetime which is important in all mobile graphics applications.

"Developers of 3D games can take full advantage of the capabilities of new high-performance graphics systems that use our GDDR3 memory technology. And notebook users will profit from our power-saving trench technology, which will give them longer battery life while they play their favorite 3D games," commented Robert Feurle, VP and GM of Infineon's Graphics Business Unit.

Infineon's 512Mb and 256Mb GDDR3 DRAM are organized as 16M x 32 and 8M x 32. These configurations allow for the design of notebook graphics with an ideal balance of frame buffer and bus width, said Infineon.

Housed in a small FBGA package of 11-by-14mm, these components are suitable for space-restricted applications such as notebook computers. The 136-ball FBGA package ball-out has lower electrical parasitic values (inductance, capacitance and resistance) to allow operation at higher speeds, and to ensure better signal integrity.
