Figure.3-1-1 MT6229 FUNCTIONAL BLOCK DIAGRAM

-19-
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.

-20-
Connectivity, and Storage
In order to take advantage of its incredible multimedia strengths, MT6229 incorporates
myriads of advanced connectivity and storage options for data storage and communication.
MT6229 supports UART, Fast IrDA, USB 1.1 Full Speed OTG, SDIO, Bluetooth and WIFI
Interface, and MMC/SD/MS/MS Pro storage systems. All these interfaces provide MT6229
users with the highest degree of flexibility in implementing solutions suitable for the targeted
application. To achieve a complete user interface, MT6229 also brings together all the
necessary peripheral blocks for a multi-media 2.75G phone. The peripheral blocks includes
the Keypad Scanner with the capability to detect multiple key presses, SIM Controller, Alerter,
Real Time Clock, PWM, Serial LCD Controller, and General Purpose Programmable I/Os.
Furthermore, to provide more configuration and bandwidth for multi-media products, an
additional 18-bit parallel interface is incorporated. This interface enables connection to LCD
panels as well as connection to NAND flash devices for additional multi-media data storage.
Audio
Using a highly integrated mixed-signal Audio Front-End, the MT6229 architecture allows for
easy audio interfacing with direct connection to the audio transducers. The audio interface
integrates D/A and A/D Converters for Voice band, as well as high resolution Stereo D/A
Converters for Audio band. In addition, MT6229 also provides Stereo Input and Analog Mux.
MT6229 supports AMR codec to adaptively optimize speech and audio quality. Moreover,
HE-AAC codec is implemented to deliver CD-quality audio at low bit rates. On the whole,
MT6229’s audio features provide a rich solution for multi-media applications.
Radio
MT6229 integrates a mixed-signal Baseband front-end in order to provide a well-organized
radio interface with flexibility for efficient customization. It contains gain and offset calibration
mechanisms, and filters with programmable coefficients for comprehensive compatibility
control on RF modules. This approach also allows the usage of a high resolution D/A
Converter for controlling VCXO or crystal, thus reducing the need for expensive TCVCXO.
MT6229 achieves great MODEM performance by utilizing 14-bit high resolution A/D
Converter in the RF downlink path. Furthermore, to reduce the need for extra external
current-driving component, the driving strength of some BPI outputs is designed to be
configurable.
Debug Function
The JTAG interface enables in-circuit debugging of software program with the ARM7EJ-S
core. With this standardized debugging interface, MT6229 provides developers with a wide
