BB5 or Base Band Generation 5 has a variety of ICs such as:
1. RAP3G/GSM (3G Radio Application Processor)
It controls the device's main work processes. The voltage obtained from the VIO retu 1.8 Volt, and Vcore 1.4 Volt from TAHVO.
2. OMAP (Open Multimedia Audio Processor)
It controls the user interface such as Camera, MMC, keypad, LCD, etc.. OMAP got a supply voltage of 1.8 Volt retu is VIO.
3. NAND Flash (APE Combo Memory)
This memory contains application data and user data User Interface settings. NAND Flash ICs have supply voltages of the VIO Power retu VDRAM 1.8 Volt and 1.8 Volt. NAND Flash is the support of other words OMAP NAND accessed by OMAP (RAP3G not access the NAND Flash).
4. NOR Flash + SDRAM (CMT Memory)
Memory contains vital data containing the main function of the phone firmware, calibration and Certificate ID. VIO supply voltage of 1.8 volts retu. NOR Flash is only accessible by RAP3G only (no access OMAP NOR Flash).
Power Suply or IC power in contrast to the DCT1 BB5-4, WD2 and Linda. In any CCONT DCT3, DCT4 UEM-WD3 there. While in BB5 itself is divided into 2 retu and TAHVO. Unlike in DCT4 (UEM) to the two ic replacement does not require or IMEI RPL because both ic does not store data only as a power supply only.
5. Retu
Main Power IC retu is assigned to provide supply voltage to the CPU, the SIM card, as well as the Startup Power and voltage other vital. Also processes the audio signal (Vibrator, Microphone, Earphone and Speaker Phone). Retu can cause damage to the total dead cell phones and other damage. Another function of the set of LED lighting retu both LCD / Keypad Led. Keypad LED will not light up when in a bright room. ALS (Ambient Light Sensor) is located in front of the phone casing in the form of light sensitive transistors.
6. TAHVO
IC Power TAHVO is second in charge also provide voltage to the CPU, the charging voltage battere (charger), flashing voltage and LED voltage.
BB5 signals in the family also differs from previous generations. Here too is divided into two parts, namely HINKU and VINKU as the executor of the signal path.
7. HINKU
HINKU is a component of the signal receiver (Receiver). Incoming signal to a mobile phone which
is then processed by Hinku RAP3G and will be sent to the speaker output.
8. VINKU
VINKU is a component of the signal transmitter (Transmitter). The incoming sound from the mic to RAP3G VINKU forwarded to and amplified by the PA and transmitted to the provider.
