STN8810/stn8811/stn8812 2/5 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. figure 1: typical system architecture using the STN8810 compactflash/cf+ nand flash nor flash sram rom ata d e v i c e keypad STN8810 low-power sdio mmc debug, trace 32 khz 13/19.2 mhz reset audio fm radio gps module usb device (e.g. 802.11xwlan) bluetooth fast irda gsm/gprs/edge xcdma modem chip set rf camera touch screen controller lcd backlight energy management codecs sdram mobile ddr sdram sdmc mmci etm9 jtag fsmc gpio i2s rtc clock, reset uart uart i2c i2c firda usb-otg pwl ssp clcd/ mdif camera interface fast synchronous modem interface tft mono/color stn smart panel tv output sd-card imagik touareg
3/5 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.
STN8810/stn8811/stn8812 4/5 open platform strategy the STN8810 is based around the mipi? software and hardware interface standard. this open platform strategy provides manufacturers with roadmap flexibility, allowing them to avoid becoming locked into a proprietary cpu architecture or vendor technology. this approach is facilitated by the following design points. the STN8810 employs the third-party arm? processor which is the standard cpu for mobile devices, with industry-wide application support. open, standard apis are provided for the development of application code on a level which is abstracted from the physical hardware. this allows the development of multimedia plug-ins that are portable between products and which can be reused on future products without modification. the STN8810 offers a rich set of peripherals and the capability of adding new smart accelerators when required. the STN8810 enables best-in-class algorithm development on its smart accelerators. stacked memory options the stn8811 and stn8812 build on the STN8810 by stacking their respective amounts of both sdram and flash memories in pin-compatible packages, a technology that stmicroelectronics has mastered for commercial use. in addition to saving space - the footprint of the stacked chips is the same as that for the STN8810, a critical factor for today?s compact clamshell designs - these stacked versions give manufacturers unprecedented flexibility on the production line. the stacked versions promise lower product costs, added system security, faster data throughput, and future performance enhancements. revision history table 1: revision history date revision description of changes february 2005 1 first issue.
