Spreadtrum Communications has introduced a portfolio of quad-core smartphone chipsets supporting both WCDMA and TD-SCDMA 3G standards for mid-range and high performance smartphones. These chipsets are now shipping in smartphones recently launched by HTC and other customers in China and Asia, and have been qualified by global operators including China Unicom, China Mobile and a major European operator, the company said.

　　Spreadtrum's flagship quad-core smartphone chipset is the SC8735S, which supports multi-mode WCDMA/HSPA+, TD-SCDMA/HSPA+ and GSM/GPRS/EDGE standards. The SC8735S incorporates a quad-core ARM Cortex-A7 CPU running at speeds up to 1.2GHz, an ARM Mali 400 MP4 GPU for high performance graphics support, integrated GPS, WiFi, Bluetooth and FM connectivity functions, as well as support for up to a 13 megapixel camera, 1080p 30fps video and full HD display. Spreadtrum's chipsets additionally support dual-SIM dual-active mode across both 3G standards.

　　Spreadtrum is also introducing the SC7735S for WCDMA/HSPA+ and the SC8835 for TD-SCDMA/HSPA+, with both supporting multi-mode operation with GSM/GPRS/EDGE standards. Like the SC8735S, both chipsets incorporate an ARM Mali 400 MP4 GPU for 3D graphics acceleration, integrate connectivity features and support dual SIM dual active function.

　　For customers targeting lower-end market segments, Spreadtrum offers the SC7730A for WCDMA and the SC8830A for TD-SCDMA, which support ARM Mali 400 MP2 GPU and dual SIM dual standby features, and are otherwise similar in feature set to their higher end counterparts.

　　The SC8735S and other chipsets in Spreadtrum's quad-core smartphone portfolio are available now and already shipping in commercial devices globally.
