STn8810 overview

The convergence of computing, multimedia and mobile communications is well underway. Already the

familiar voice phone is being transformed into a personal device with a wide range of multimedia capabilities.

Soon mobile users will be able to benefit from a broad spectrum of multimedia features and services, to

include capturing, sending and receiving images, videos and music. To deliver such data-heavy, processing-

intensive services, portable handheld systems must be optimized for high performance but low power, space

and cost.

In response to this need, the STn8810 processor platform from STMicroelectronics is a culmination of

breakthroughs in video coding efficiency, inventive algorithms and chip implementation schemes. It will

enable smart phones, wireless PDAs, internet appliances and car entertainment systems to play back media

content, record pictures and video clips, and perform bidirectional audio-visual communication with other

systems in real time.

The STn8810 focuses on the essential features to meet the future needs of mobile products and services: a

high-performance multimedia capability coupled with low power consumption, and based on an open

platform strategy.
