1. INTRODUCTION
1.1Purpose
This manual provides information necessary to repair, description and download the features
of this model.
1.2 Regulatory Information
A. Security
Toll fraud, the unauthorized use of telecommunications system by an unauthorized part(for
example ,persons other than your company’s employees, agents, subcontractors, or person
working on your company’s behalf) can result in substantial additional charges for your
telecommunications services.
System users are responsible for the security of own system. There are may be risks of toll
fraud associated with your telecommunications system. System users are responsible for
programming and configuring the equipment to prevent unauthorized use .The manufacturer
dose not warrant that this product is immune from the above case but will prevent unauthorized
use of common-carrier telecommunications service of facilities accessed through or connected
to it.
The manufacturer will not be responsible for any charges that result from such unauthorized
use.
B. Incidence of Harm
If a telephone company determines that the equipment provided to customer is faulty and
possibly causing harm or interruption in service to the telephone network, it should disconnect
telephone service until repair can be done. A telephone company may temporarily disconnect
service as long as repair is not done.
C. Changes in Service
A local telephone company may make changes in its communications facilities or procedure. If
these changes could reasonably be expected to affect the use of the this phone or compatibility
with the network, the telephone company is required to give advanced written notice to the user,
allowing the user to take appropriate steps to maintain telephone service.
D. Maintenance Limitations
Maintenance limitations on this model must be performed only by the manufacturer or its
authorized agent . The user may not make any changes and/or repairs expect as specifically
noted in this manual.
Therefore, note that authorized alternations or repair may affect the regulatory status of the
system and may void any remaining warranty.

E. Notice of Radiated Emissions
This model complies with rules regarding radiation and radio frequency emission as defined
by local regulatory agencies. In accordance with these agencies, you may be required to provide
information such as the following to the end user.
F. Pictures
The pictures in this manual are for illustrative purposes only; your actual hardware may look
slightly different.
G. Interference and Attenuation
Phone may interfere with sensitive laboratory equipment, medical equipment, etc.
Interference from unsuppressed engines or electric motors may cause problems.
H. Electrostatic Sensitive Devices
ATTENTION
Boards, which contain Electrostatic Sensitive Devices(ESD),are indicated by the
sign .
Following information is ESD handing:
. Service personnel should ground themselves by using a wrist strap when exchange system
boards.
.When repairs are made to a system board , they should spread the floor with anti-static mat
which is
also grounded .
.Use a suitable, grounded soldering iron .
. Keep sensitive parts in these protective packages until these are used.
.When returning system boards or parts like EEPROM to the factory, use the protective
packages as
described.

3.TECHNICAL BRIEF
3.1 Digital Main Processor
Figure.3-1-1 MT6223 FUNCTIONAL BLOCK DIAGRAM

20
3.1.1 System Overview
MT6223D is an entry level chipset solution with class 12 GPRS/GSM modem. It integrates not
only analog baseband but also power management blocks into one chip and can greatly reduce the
component count and make smaller PCB size. Besides, MT6223D is capable of SAIC (Single
Antenna Interference Cancellation) and AMR speech.
Based on 32 bit ARM7EJ-STM RISC processor, MT6223D provides an unprecedented
platform for high quality Modem performance.
Platform
MT6223D runs the ARM7EJ-STM RISC processor at up to 52Mhz, thus providing best trade-off
between system performance and power consumption.
For large amount of data transfer, high performance DMA (Direct Memory Access) with
hardware flow control is implemented, which greatly enhances the data movement speed while
reducing MCU processing load.
Targeted as a modem-centric platform for mobile applications, MT6223D 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
MT6223D supports up to 2 external state-of-the-art devices through its 16-bit host interface.
Devices such as burst/page mode Flash, page mode SRAM, and Pseudo SRAM are supported. 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
MT6223D utilize high resolution audio DAC, digital audio, and audio synthesis technology to
provide superior audio features., e.g. MP3 ring tone.
Connectivity, and Storage
MT6223D supports UART as well as Bluetooth interface. Also, necessary peripheral blocks are
embedded for a voice centric phone: 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.
Audio
Using a highly integrated mixed-signal Audio Front-End, architecture of MT6223D 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, MT6223D also provides Stereo Input and
Analog Mux. MT6223D also supports AMR codec to adaptively optimize speech and audio quality.
