4 Introduction
4.1 Overview
ATJ2259B is highly integrated 32bit RISC-based SOC for media solution. The RISC
architecture and high speed bus controller can achieve high performance and low power
dissipation. With a built-in media coprocessor, its media platform can deal with MJPEG,
MPEG4, H263, H264 and WMV format more efficiently. A USB v2.0 (HS) SIE with OTG
function was integrated, making the platform act as a host or slave mass storage device at
the speed up to 480Mbps. The audio codec in the SOC is based on delta-sigma modulation,
which can get high performance with low power and allow the flexible adjustment of sample
rate from 8k to 96k. The built-in audio codec can switch inputs within headphones,
microphone and FM radio and direct drive the low impedance earphone. ATJ2259B also
provides TVOUT for PAL/NTSC CODEC, easily converting video signal between analog and
digital. For various memories, the SOC integrates SRAM, SDRAM, FLASH, SD/MMC, MS etc.
The platform also offers I2C, SPI, UART, IR and SPDIF interfaces for changeful control and
transfer modes. Thus, ATJ2259B provides a true “ALL-IN-ONE” solution that is ideally suited
for highly optimized digital media devices.
