SAMSUNG Proprietary-Contents may change without notice2-2-3. AudioYMU765 has a built-in amplifier, and thus, is an ideal device for outputting sounds that are used by mobile phonesin addition to game sounds and ringing melodies that are replayed by a synthesizer.The synthesizer section adopts "stereophonic hybrid synthesizer system" that are given advantages of both FMsynthesizers and Wave Table synthesizers to allow simultaneous generation of up to 32 FM voices and 32 WaveTable voices. Furthermore, YMU765 has a built-in hardware sequencer that helps to realize complex play withoutheavily loading the host CPU. And this device also has a built-in circuit for controlling vibrators and LEDssynchronizing with play of music. The consumed electric current can be stopped to the minimum by power downmode when not operating.The hardware sequence built in this device allows playing of the complex music without giving excessive load to theCPU of the portable telephones. Moreover, the registers of the FM synthesizer can be operated directly for real timesound generation, allowing, for example, utilization of various sound effects when using the game software installedin the portable telephone.2-2-4. MemoryThe signals in the MSM6250 enable two memories. They use volt supply voltage, VREG_MSMP, VREG_MSMEfrom the PM6650. This system uses SEC's memory, KBE00F005M-F411. It is consisted of 1G bits flash NANDmemory and 512M bits SDRAM memory. It has 16 bit data line, D1[0~15] which is connected to MSM6250.2-2-5. CameraThe camera module consists of VGA pixel of system LSI(Samsung Techwin), 1/5.8" VGA CMOS image sensor withan embedded image signal processor. Pixel size is 4.0 um and effective resolution is 640(H) x 480(V).2-2-6. IrdaThis system uses IRDA module, HSDL_32085, Agilent's. It uses two power signals, "VREG_MSMP" for circuit and"VBATT" for LED.2-2-7. BluetoothThis system uses Bluetooth module, LBDA245AN0, Murata's. Chip solution is of Broadcom, BCM2004. It uses apower signal, "VREG_BT". This system uses Blue-Q interface in that module has RF circuit and base band bluetoothpart is in MSM6250.
