Spreadtrum SC6531 chipset

Just recently, China-based fabless company Spreadtrum Communications Inc. had announced that its first mobile base band chipset with integrated wireless connectivity is now commercially available. Called the SC6531, the chipset integrates Spreadtrum's 40nm based GSM/GPRS mobile base band platform with FM and Bluetooth. It is capable of delivering a high level of integration for 2.5G feature phone handset makers.

"The SC6531, designed with 40nm CMOS silicon, provides customers with the benefit of the most advanced process technology for GSM/GPRS base band chipsets, a mature, proven platform with extensive development tools for handset customisation, and a high level of integration that brings together the mobile base band, RF transceiver, PMU, FM and Bluetooth features into a single base band SoC," said Dr. Leo Li, president and CEO of Spreadtrum Communications. "This combination of advanced technology, platform maturity and high integration supports our customers' strategy of bringing to market high quality, cost-competitive handsets with differentiated features. We are happy to see that this 40nm SC6531 not only is commercially available for general markets, it has also passed the rigorous quality tests of a major European operator. This achievement testifies to the high level of quality of our new 40nm products."
