I. Processor
Second processor that play important role as brain from handphone:

Each processor has memory self. Rap3g has nor flash+sdram, While omap with ape combo memory

Ii. Memory

As data repository that wanted by handphone is used kind memory as follows:

Nand flash (ape combo memory) that accessinged by omap processor. Memory this contain application datas with user interfaces user arrangement data. Nand flash get supply tension from ic power retu that is vio 1,8 volt and Vdram 1,8 volt.

Nor flash+sdram (cmt memory) that is memory that contain principal function vital datas from handphone contain firmware, Calibrate and Certificates id. Supply tension vio 1,8 volt from retu.

Iii. Regulator power supply

Component power supply or More knowledgeable with the title ic power in handphone bb5 this also divided be two parts that is:

Retu ic power principal that have a duty to give supply tension in cpu, Sim card, With startup power and Another vital tension. Also processed signal audio (vibrator, Microphone, Arphone and Speaker phone). Damage in retu dpt causes handphone dies total and Another damage.

Function other from retu that is regulate illumination led good lcd/keypad led. Keypad led will not burn moment will reside in bright room. Als (ambient light censor) this lay in casing in front of handphone shaped photosensitive transistor.

Tahvo ic power second that have a duty also give tension to cpu, Admission filling tension battere (charger), Tension flashing, With tension led.

Doesn't like dct4, In ic powernya uem that contain number security data imei, So in retu and Tahvo there is no security data inside, So that replacement retu and Tahvo this is not need admission filling security area as does dct4.
