Component And Function Part 2

6. MCU (Master Control Unit) 

MCU is program or datas exist in handphone bound in audio IC, this data has permanent or from factory, like: handphone program version, IMEI, year maker, and phone code. In nokia generation dct-3, we can take this data from other handphone in good condition then can save it in computer as data reference (extention *. fls). One file *. fls extention keep two datas that is MCU and PPM if we use program flasher dct-3. But if use program griffin, ufs-3, prodigy, jaf, or program flasher newest another so the program permanent divided will be two, that is mcu and ppm, only to discern that MCU file usually ended with number 0 while PPM it is end with font/alphabet. But not all handphone kinds be taken the data, like handphone that belong to dct-4 or another new handphone because there aredata that provided by programmer. Usually extention from datas like mcu it’s permanent and number 0, then ppm also extention with font/alphabet, except for handphone nokia 3650,7650 and 6600, or new handphone extention cx or c1 to mcu.

 7. PPM 
This data is much the same with MCU, but only specialize in language, ringtone/polyphonic, and standard program from handphone. This data is is not has permanent or canbe chage and add new programs. 

8. IC RAM 
this component is basically is also data storage, but in character only temporary, because component in the work manner depend on electricity current that flow in series. if handphone deadens so directly data will lost by itself. This component is very related tight with activity CPU. ever greater Capacity from RAM so CPU in good performance, but if RAM damage so CPU can not work. 
 
9. Charging IC
this component works automatically moment charging battery, functioned to charge and regulate voltage charging battery that controlled by CPU by controlling IC. 

10. UI IC
functioned as that data controlling by CPU IC in vibrator, buzzer, led and has as automatic electric switch in handphone.
11. ic pa 
he function as amplify end signal that be radiated throught component antenna switch found on handphone. 
 
12. IC RF 

Functioned as signal controlling rx (receiver) and tx (tranceiver), so that every part can work well. This component consists of some part that is: If, Mixer, Oscilator, Detektor, Enkoder, Dekoder, Afc, Tone Frequency And Squelch.

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.
