General description
The convergence of computing, multimedia and mobile communications is well underway.
The familiar voice phone is being transformed into a personal device with a wide range of
multimedia capabilities including capturing, sending and receiving images, videos and
music. To deliver such data-heavy, processing-intensive services, portable handheld
systems must be optimized for performance and low power, space and cost.
In response to this need, the STn8811A12 processor platform from STMicroelectronics is a
culmination of breakthroughs in video coding efficiency, inventive algorithms and chip
implementation schemes. It will enable smart phones, portable media players, portable
navigation devices, internet appliances and car entertainment systems to play back media
content, record pictures and video clips, receive mobile-TV and perform bidirectional audiovisual communication with other systems in real time.
The STn8811A12 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.

STn8811A12 overview
Main features
The STn8811A12 processor platform enables compelling multimedia applications by means
of its unique distributed-processing architecture. The application processor features lowpower 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:
1.5
●
A smart video accelerator for VGA video encoding and decoding, with MIPI 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/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 (OS).
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 STn8811A12 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 off load 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.

STn8811A12
Open platform strategy
The STn8811A12 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.
6/17
●
The STn8811A12 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 STn8811A12 offers a rich set of peripherals and the capability of adding new smart
accelerators when required.
●
The STn8811A12 enables best-in-class algorithm development on its smart
accelerators.

The PMU controls the external voltage regulator, in order to change its settings in different
modes. In deep-sleep mode, only GPIOs, the real-time clock (RTC), system and reset
controller (SRC), PMU and secured RAM remain in operation. The PMU also controls the
embedded 1.2 V voltage switch that switches off the logic supply after the platform has
entered sleep mode.

9/17
Architecture overview
2.9
STn8811A12
Real time clock (RTC)
The RTC provides a 1-second resolution clock. This keeps time when the system is inactive
and can be used to wake the system up when a programmed alarm time is reached. It has a
clock trimming feature to compensate for the accuracy of the 32.768 kHz crystal and a
secured time update.
2.10
Timers
The STn8811A12 provides eight 16- or 32-bit (configurable) timers, as two groups of four.

2.12
Vectored interrupt controller (VIC)
The VIC allows the OS interrupt handler to quickly dispatch interrupt service routines in
response to peripheral interrupts. There are 32 interrupt lines and the VIC uses a separate
bit position for each interrupt source. Software controls each request line to generate
software interrupts.
2.13
System and reset controller (SRC)
The SRC provides a control interface for clock generation components external to the
subsystem. It also controls system-wide and peripheral-specific energy management
features.
2.14
Direct memory access (DMA) controllers

STn8811A12
Master display interface (MDIF)
This interface drives LCD display modules, that is, panels that include their own display
memory and perform LCD panel refresh themselves. The MDIF is a parallel bidirectional
interface that can send commands or data to or read data from the display panel logic. It has
a DMA engine to automatically fetch data/commands from main memory without CPU
intervention.
2.21
Pulse width light modulator (PWL)
The PWL provides control of LCD backlighting. It produces a series of pulses that are fed to
the backlighting, where the width (or duty cycle) of the pulses determines the perceived
lighting level. An 8-bit random sequence generator decreases the spectral power at the
modulator harmonic frequencies.
2.22
General purpose inputs/outputs (GPIOs)
The STn8811A12 provides 96 programmable inputs or outputs that have switchable pull-up

The GPIO interface provides the following individually programmable functions:
2.23
●
Any number of pins may be configured as interrupt sources
●
Debouncing logic can be enabled for each GPIO to filter out glitches on I/Os
●
Any GPIO may be used to wake up the device from sleep mode independent of
interrupt programming, and the input level that triggers wake-up is definable for each
enabled GPIO.
MultiMediaCard/secure data card interface (MMC/SD)
This interface can directly control one SD card (without encryption/decryption logic) or one
MultiMediaCard. It also supports several of each card type using the GPIOs for card
selection.
