3.1.1 System Overview 

MT6229 is a feature-rich and extremely powerful single-chip solution for high-end mobile 

phones with GSM/GPRS and EDGE capability. Based on 32 bit ARM7EJ-STM RISC 
processor, MT6229’s superb processing power along with high bandwidth architecture and 
dedicated hardware support provides an unprecedented platform for high performance 
EGPRS Class 12 MODEM and leading-edge multimedia applications. To sum up, MT6229 
presents a revolutionary platform for multimedia-centric mobile devices along with an EDGE 
capable modem.   
    Typical application diagram is shown in

 Figure3- 1

. 

 
Platform  

    MT6229 is capable of running the ARM7EJ-STM RISC processor at up to 104Mhz, thus 
providing fast data processing capabilities. In addition to the high clock frequency, separate 
CODE and DATA caches are also added to further improve the overall system efficiency. For 
large amount of data transfer, high performance DMA (Direct MemoryAccess) with hardware 
flow control is implemented, which greatly enhances the data movement speed while reducing 
MCU processing load. Targeted as a media-rich platform for mobile applications, MT6229 
also provides hardware security digital rights management for copyright protection. For further 
safeguarding, and to protect manufacturer’s development investment, hardware flash content 
protection is also provided to prevent unauthorized porting of software load.   

 
Memory  

    To provide the greatest capacity for expansion and maximum bandwidth for data intensive 
applications such as multimedia features, MT6229 supports up to 4 external state-of-the-art 
devices through its 8/16-bit host interface. High performance devices such as Mobile RAM, 
and Cellular RAM are supported for maximum bandwidth. Traditional devices such as 
burst/page mode Flash, page mode SRAM, and Pseudo SRAM are also supported. For 
greatest compatibility, the memory interface can also be used to connect to legacy devices 
such as Color/Parallel LCD, and multi-media companion chip are all supported through this 
interface. To minimize power consumption and ensure low noise, this interface is designed for 
flexible I/O voltage and allows lowering of supply voltage down to 1.8V. The driving strength is 
configurable for signal integrity adjustment. The data bus also employs retention technology 
to prevent the bus from floating during turn over. 

 
Multi-media 

TheMT6229 multi-media subsystem provides connection to CMOS image sensor and 

supports resolution up to 3M pixels.With its advanced image signal and data processing 
technology, MT6229 allows efficient processing of image and video data. It also has built-in 
JPEG CODEC and MPEG-4/

H.263 

CODEC, thus enabling real-time recording and playback 

of high-quality images and video. Hardware MPEG4/

H.263 

accelerator supports playback in 

VGAmode at 15fps, and encoding in CIF at 15fps. Videophone functionality is also provided. 
Moreover, high quality de-blocking filter is provided to remove blocking artifacts in video 
playback. GIF decoder and PNG decoder are implemented as well for fast image decoding. 
MT6229 also supports TV-OUT capability, thus allowing the mobile handset to connect to TV 
screen via NTSC/PAL connections. In addition to advanced image and video features, 
MT6229 also utilizes high resolution DAC, digital audio, and audio synthesis technology to 
provide superior audio features for all future multi-media needs.
