1.1

Key benefits

The STn8810S12 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,

●

Ultra-integrated system package.

1.2

Main features

The STn8810S12 system-in-package 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

STn8810S12 incorporates additional memory in a much reduced area using advanced

packaging processes.

The main features of the system 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,

●

A power management unit which offers a number of power saving modes,

●

The ARM926EJ processor, a powerful industry-standard CPU,

●

Self-contained memory resources:

–

Processor on-chip ROM and SRAM memory devices,

–

1-Gbit NAND Flash memory,

–

512-Mbit DDR mobile RAM.

●

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, color LCD and camera interfaces),

●

Minimal support for high-level operating system such as Symbian™, Linux and

WinCE® operating systems.
