1. INTRODUCTION
1. INTRODUCTION
1.1 Purpose
This manual provides the information necessary to repair, calibration, 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 does not warrant that this
product is immune from the above case but will prevent unauthorized use of common-carrier
telecommunication 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 phones or compatibility with the net
work, the telephone company is required to give advanced written notice to the user, allowing the user
to take appropriate steps to maintain telephone service.

1. INTRODUCTION
D. Maintenance Limitations
Maintenance limitations on the phones 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 unauthorized 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
A 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 Device (ESD), are indicated by the sign.
Following information is ESD handling:
• 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 package as
described.

- Access Central Processing Unit (CPU) subsystem – ARM926, Joint Test Action Group (JTAG),
Embedded Trace Module (ETM), Instruction and Data (I&D)-cache, and I&D-TCM
- Access peripheral subsystems – Subscriber Identity Module (SIM) interface, IrDA®, Universal
Serial Bus (USB), Universal Asynchronous Receiver/Transmitter (UART), and so on
- Digital Signal Processor (DSP) subsystem – CEVA-X1620, JTAG, Static Random Access
Memory (SRAM), and Program Data Read Only Memory (PDROM)
- EDGE/GSM/GPRS (EGG) subsystem – EGG hardware accelerators
- WCDMA subsystem – WCDMA hardware accelerators
• Application subsystem
- Application CPU subsystem – containing ARM926, JTAG, ETM, I&D-cache, and I&D-TCM
- Application peripheral subsystems – I2C™, keypad, UART, and so on
- Graphics subsystem – XGAM subsystem
- Audio Processing Execution (APEX) and video encoder subsystems
In addition to the two subsystems above, there is also a test block, chip control block, and
a pad multiplexing block residing at the top level
yDSP
- The Digital Signal Processor Subsystem (DSPSUB) includes a DSP megacell, which
contains the DSP CPU together with a tightly coupled memory. The DSP is the Ceva-X
1620 core with a 64 KiB instruction RAM and a 64 KiB data RAM. It also contains debug
logic and interfaces. In addition to the megacell, the DSPSUB includes external memories,
peripheral units, and interfaces. The DSP megacell is clocked at 208 MHz.
- The DSPSUB includes an AHB master and an AHB slave interface. The AHB master
provides a direct access to the Internal Random Access Memory (IRAM) in the EGG core
through the AHB. The AHB slave interface allows the CPU and the DMA to access in the
program and data RAM residing in the DSPSUB.
yWCDMA subsystem
- The digital baseband controller WCDMA subsystem incorporate a WCDMA modem
- An interface to the WCMDA together with memory control and an internal single port
RAM. The WCDMA subsystem has three AHB slave interfaces.
- The Ericsson DB 3200 also includes HSDPA class 6 functionality.
- The WCDMA subsystem is handled and provided by Ericsson.
yXGAM subsystem
- The XGAM subsystem is a graphics acceleration module that provides hardware
support in the creation of visual imagery and the transfer of this data to a display.
The XGAM also provides support for connecting a Camera module. The visual data
could be graphics, still images, or video.
- The XGAM subsystem is handled and provided by Ericsson.
yOperation and Services
- I²C™ Interface
-SIMInterfaces
- General Purpose I/O (GPIO) Interface
- External Memory Interface that supports NAND, NOR, PSRAM, SDRAM,
-JTAG
-RTC
-ETM9
