ST Microelectronics STN8810
STn8810/STn8811/STn8812
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.

ST Microelectronics STN8810
STn8810/STn8811/STn8812
Key benefits
The STn8810 brings the following key benefits to mobile manufacturers and consumers:
Unsurpassed audio and video quality,
Ultra-low power consumption for longer battery operation,
Easier application development for shorter time-to-market,
Scalability for multiple market segments and future multimedia applications.
Main features
The STn8810 processor platform enables compelling multimedia applications by means of its unique
distributed-processing architecture. The application processor features low-power smart accelerators which
handle all audio and video functions. These free the main CPU for control and program flow tasks, or allow
the CPU to enter power-saving modes to prolong battery life. The smart accelerators operate independently
and concurrently to ensure the lowest absolute system power and deterministic high-performance.
The main features of the platform are:
A smart video accelerator for VGA video encoding and decoding, with camera interfaces,
A smart audio accelerator containing a comprehensive set of digital audio decoders and
encoders, and offering a large number of 3-D surround effects,
An advanced power management unit which offers a number of power saving modes,
The ARM926EJ processor, a powerful industry-standard CPU with Java acceleration,
On-chip ROM and SRAM memory devices,
Advanced security framework for authentication and digital rights management,
Multichannel DMA controller for efficient data transfer without CPU intervention,
A multi-layer AMBA crossbar interconnect for optimized data transfers between the CPU,
accelerators, memory devices and peripherals,
A wide range of peripheral interfaces (GPIO, USB-OTG, UART, I²C, FIrDA, SD/SDIO/MMC,
serial ports, TV output, color LCD and camera interfaces),
Direct support for high-level operating system such as Symbian™, Linux and WinCE® operating
systems (OSs).
Low power consumption
The new multimedia functionality of mobile products brings with it an increase in power consumption that is
outpacing advances in battery technology. The STn8810 chip saves on power by avoiding the need for high
clock speeds wherever possible, but its extremely low power consumption results from a systematic effort at
all design levels to reduce power requirements.
These include:
The use of smart accelerators and distributed processing to offload from the CPU,
Efficient code execution by means of innovative algorithms, energy-efficient instruction set
architectures and Java acceleration,
The efficient use of bandwidth for on-chip data transport, achieved by data compression,
buffering and image scaling,
Aggressive power management which includes turning off inactive parts of the chip and keeping
the CPU in power-saving modes as much as possible.
