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.
