New platform promises low-cost, high-performance smartphones

Attention: open in a new window.

2012 may be the year of the low-cost smartphone following the introduction of a 1GHz Android smartphone platform for TD-SCDMA (SC8810) and EDGE/WiFi (SC6820) by Chinese semiconductor provider Spreadtrum. The two products, both now sampling with customers, enable OEMs to deliver 1GHz performance at US$100 retail prices.

“Our 1GHz Android platform sets a new bar for low-cost smartphone performance,” said Dr. Leo Li, Spreadtrum’s president and CEO. “The graphics and web browsing performance of the SC8810 and SC6820 compares favourably to one of the most popular smartphone models globally, delivering a high performance applications and gaming experience for consumers. This type of experience has previously been available only in mid- to high-end handset models and can now be delivered by OEMs in US$100 smartphone models. This will reshape the definition of and consumer expectations for a low-cost handset.”

The 1GHz platform is the most highly integrated, lowest power smartphone platform for the TD-SCDMA market. The solution delivers the lowest chip count with a multimode single-chip RF transceiver supporting TD-SCDMA, EDGE, GPRS and GSM and integrates power management. The platform’s Cortex A5 processor architecture delivers more than 40% lower power consumption compared to ARM11-based products and more than 70% lower power consumption than Cortex A9 products, delivering differentiated standby and talk time performance relative to other smartphone models.

Designed with 40nm CMOS silicon technology, the SC8810 and SC6820 baseband platforms are powered by a Cortex A5 1GHz processor and incorporate an advanced multimedia subsystem which includes a Mali GPU with 3D/2D graphics acceleration and supports high definition video playback, a 5 megapixel camera, a WVGA touch panel and connectivity features including Bluetooth, WiFi and GPS.

The SC8810 supports TD-SCDMA with HSDPA at 2.8Mbps, HSUPA at 2.2Mbps as well as quad-band GSM/GPRS/EDGE with dual-mode auto handover, while the SC6820 supports quad-band EDGE/GPRS/GSM. Both products combine silicon hardware with turnkey Android software that reduce both the design time and design resources required to deliver new handsets to market.

Demand for smartphones in emerging markets, and particularly China, is increasing dramatically. Industry analysts expect the smartphone market in China to exceed 100 million units in 2012, leading the global demand for smartphone products.
