CAUTIONS
Please refer to the phone’s user’s guide for instructions relating to operation, care, and maintenance, which
include important safety information.
Servicing and alignment must be undertaken by qualified personnel only.
Ensure all work is carried out at an anti-static workstation and that an anti-static wrist strap is worn.
Use only approved components as specified in the parts list.
Ensure all components, modules, screws, and insulators are correctly re-fitted after servicing and alignment
Ensure all cables and wires are repositioned correctly
Electrostatic discharge can easily damage the sensitive components of electronic products. Therefore, every
service supplier must observe the precautions which mentioned above.

MT6589 INTRODUCTION
7.1 Baseband CPU circuit introduction for power supply
7.2 Introduction for baseband chip CPU part circuit
System Overview
MT6589 is a highly integrated baseband platform incorporating both modem and application processing subsystems to
Enable 3G smart phone applications. The chip integrates a Quad-core ARM Cortex-A7 MPCore operating up
to 1.2GHz, an ARM Cortex-R4 MCU and a powerful multi-standard video accelerator. The MT6589 interfaces to
NANA flash memory, 32-bit mobile DDR or LPDDR2 for optimal performance and also supports booting from SLC
NAND or EMMC to minimize the overall BOM cost. In addition, an extensive set of interfaces and connectivity
peripherals are included to interface to cameras, touch-screen displays, MMC/SD cards and external Bluetooth,
WILAN and GPS modules.

MT6628 is a 4-in-1 wireless communication device which includes
. WLAN
. Bluetooth
. GPS
. FM Transmitter and receiver
With four advanced radio technologies integrated into a single chip, MT6628 provides the best and most
convenient Connectivity functions. MT6620 implements advanced and sophisticated Radio antenna for
Bluetooth and WLAN,5GHz for WLAN and 1.575GHz for GPS).Enhanced overall quality for simultaneous
voice data, and audio/video Transmission on mobile phone and Tablet PC can be achieved. The small size with
low power consumption reduces PCB layout area the software package “Symphony”enables all advanced
wireless features on Android OS.
