STn8810S12 general description
STn8810S12
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.
