Component and Function Part 1

several important components found on handphone alongs with the function

1. Power IC (CCONT) 
To distributed current and voltage 
 
2. Audio IC (COBBA) 
this IC has function as voice signal processor that enter from RF IC, then at strengthen and sustained to speaker, amplify that in advance by mic be electricity oscillation then sustained to RF IC, run command from CPU. in Audio IC also found PCM (Pulse Code Module) and EEPROM that functioned to read signal code receive from operator to suited with handphone imei. beside that also functioned to keep data’s has permanent like imei, phone code, etc. 
 
3. CPU IC
CPU is electronics component integration and will be functioned as according to the task each. this component has task very significant, because this component is brain from a handphone. Equally cpu centre from handphone system work. 
 
4. IC FLASH 
functioned as handphone data storage not permanent equally can be changed or add with datas in computer. this tool is same the function with hard disk in computer. 
 
5. EEPROM (Electrically Erase Programable Read Only Memory) 

this component functioned as data repository in handphone that designed doesn't irrespective electricity current existence from handphone, because there are special battery or have electricity current, usually this component keeps factory data likes imei1, imei 2, security code, program version and maker date. but for brand handphone nokia data newest product found on this component is irreversible. 

to be continue in Component and Function Part 2

Data and Audio Part

Data Part

Data Part functioneds as operating system that cultivate data and give command to entire parts found on part mobile phone. Data Part component consist of :

1. IC CPU
2. IC RAM
3. IC FLASH 
4. KEYPAD 
5. LCD 

Function CPU with support component is: 
1. IC CPU is data processing centre in handphone 
2. IC CPU work helped by IC RAM as saving operating system / program that walk in cellular telephone and IC FLASH that keep temporary data’s, and can be changed direct in mobile phone if user willing. 
3. while keypad here have functioned to command CPU to do data process appropriate handphone user willing 
4. LCD is getting command from CPU to displaying entire process that are walking in handphone. 
 
procedure every part : 
1. Data has been entered into to handphone has passed program that is on cable flash (to flasher) and data cable (to application) 
2. Data from computer that is PPM and MCU step into Ic Flash and Ic Flash keep data Ppm that consist of menu, application and language, this data kind temporary and convertible direct by user 
3. While data MCU sent to EEPROM (Elctrically Erase Programable Read Only Memory) that consist of handphone identity that is IMEI, sec. code and phone code 
4. CPU helped by IC RAM functioneds to processed data PPM exist in flash IC to sustained to ic hardware and displayed in screen (LCD) and check data in EEPROM as handphone identity to recognizable by CPU. 

Data Processing Diagram 
in newest cellular telephone set in this time there are some IC that is united to be one or integration, like: 
IC UEM/UAM 
this component has consisted of several components that integration, among others: 
Ic Power Supply 
Ic Audio 
Ic Charging 
Ic UPP 
this component has consisted of several components that integration, among others: 
1. IC CPU
2. IC EEPROM 
3. Ic Flash 

Audio Part 
that part in this component: 
Ic audio 
Loud speaker / ring tone poliponik 
Microphone 
1. Ic audio as voice signal vibration amplifiying sustained to loud speaker as voice signal vibration changer is voice vibration. 
2. Microphone will change voice vibration will be voice signal vibration that Amplified by Ic Audio. 
for telephone set kind selularl ringtone polyponik also cultivated by ic audio and sustained to loud speaker ringtone 
 
procedure every part: 
1. IC Audio gets voice signal from RF IC to Amplified and continued to loudspeaker 
2. In loudspeaker voice signal be be changed to be voice vibration so that audible. 
3. Microphone change voice vibration is voice signal and sustained to ic audio 
4. In voice ic signal audio is braced and amplified to RF IC to at transmit to pass part TX. 
5. Function CPU as controlling from work audio IC and regulate performance data IC formed audio. 
6. Voltage that step into IC audio that is Vbb as stanby voltage, Vcobba as voltage input moment to work it entire parts in audio ic and voltage vref as detector / voltage controlling into audio Ic.
