the motor.
3. IRDA
This system uses IRDA module, HSDL_3201. This has signals, "IRDA_DOWN"(enable signal),
"RXD0"(input data) and "TXD0"(output data). These signals are connected to OM6357.
It uses two power signals. "VDD2" is used for circuit and "VBAT" is used for LED.
4. Key
This is consisted of key interface pins among OM6357, KBIO(0:7). These signals compose the
matrix. Result of matrix informs the key status to key interface in the OM6357. Power on/off
key is separated from the matrix. So power on/off signal is connected with PCF50601 to enable
PCF50601. twelve key LED use the "VBAT" supply voltage. "VDD_KEY" signal enables
LEDs with current control. "FLIP" informs the status of folder (open or closed) to the OM6357.
This uses the hall effect IC, A3212ELH. A magnet under main LCD enables A3212ELH.
5. EMI ESD Filter
This system uses the EMI ESD filter, EMIF09 to protect noise from IF CONNECTOR part.

8. Audio
EARP_P and EARP_N from OM6357 are connected to the main speaker. AUXSP is connected to
the Hands free kit. MIC_P and MIC_N are connected to the main MIC. And AUX_MIC_P and
AUX_MIC_N are connected to the Hands free kit.
YMU762MA3 is a LSI for portable telephone that is capable of playing high quality music by
utilizing FM synthesizer and ADPCM decoder that are included in this device.
As a synthesis, YMU762MA3 is equipped 32 voices with different tones. Since the device is
capable of simultaneously generating up to synchronous with the play of the FM synthesizer,
various sampled voices can be used as sound effects.
Since the play data of YMU762MA3 are interpreted at anytime through FIFO, the length of the
data(playing period) is not limited, so the device can flexibly support application such as incoming
call melody music distribution service. The hardware sequencer built in this device allows playing
of the complex music without giving excessive load to the CPU of the portable telephones.
Moreover, the registers of the FM synthesizer can be operated directly for real time sound
generation, allowing, for example, utilization of various sound effects when using the game
software installed in the portable telephone.
YMU762 includes a speaker amplifier with high ripple removal rate whose maximum output is
550mW (SPVDD=3.6V). The device is also equipped with conventional function including a
vibrator and a circuit for controlling LEDs synchronous with music. For the headphone, it is
provided with a stereophonic output terminal.
For the purpose of enabling YMU762MA3 to demonstrate its full capabilities, Yamaha purpose to
use "SMAF:Synthetic music Mobile Application Format" as a data distribution format that is
compatible with multimedia.
Since the SMAF takes a structure that sets importance on the synchronization between sound and
images, various contents can be written into it including incoming call melody with words that can
be used for training karaoke, and commercial channel that combines texts, images and sounds, and
others.
The hardware sequencer of YMU762MA3 directly interprets and plays blocks relevant to synthesis
(playing music and reproducing ADPCM with FM synthesizer) that are included in data distributed
in SMAF.

KBIO(0:7), address lines of DSP core and HD[0~15]. HA[1~23], address lines of ARM core and
HD[0~15], data lines of ARM core are connected to memory.
NCSRAM, NCSFLASH_NAND in the ARM core are connected to each memory. HWR_N and
HRD_N control the process of memory. External IRQ(Interrupt Request) signals from each units,
such as, PMU need the compatible process.
KBIO[0~7] receive the status from key and RXD0/TXD0/IrDA_DOWN are used for the
communications using IRDA and data link cable(DEBUG_DTR/RTS/TXD/RXD/CTS/DSR).
