MA-3
Mobile Audio 3
Outline
MA-3 is a synthesizer LSI for mobile phones that realize advanced game sounds.
This LSI has a built-in speaker amplifier, and thus, is an ideal device for outputting sounds that are used by mobile
phones in 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 FM
synthesizers and Wave Table synthesizers to allow simultaneous generation of up to thirty two FM voices and eight
Wave Table voices.
Since FM synthesizer is able to present countless voices by specifying parameters with only several tens of bytes,
memory capacity and communication band can be saved, and thus, the device exhibits the features in operating
environment of mobile phones such as allowing distribution of arbitrary melodies with voices.
On the other hand, Wave Table synthesizer can pronounce the voice built in ROM and arbitrary ADPCM/PCM voices
from sequencer by the download of the melody with voices etc..
MA-3 has a built-in hardware sequencer that helps to realize complex play without heavily loading the host CPU.
The device also has a built-in circuit for controlling vibrators and LEDs synchronizing with play of music.
Features
MA-3 has features as described below.

CPU interface is an 8-bit parallel type.
- ”Instantaneous write path” that enables Write command immediately (equipped with 64byte FIFO),
- ”Delayed write path” that enables Write command after elapse of specified time, and
- Instantaneous read path
are available.
Hardware sequencer and FIFO
The sequencer is a block that controls time and register access.
The structure of sequence data includes “time information data + MA-3 register control data”, for which 512 byte FIFO
is provided. The sequence data is written into delayed write path.
FM+Wave Table synthesizer
This device contains a Polyphonic synthesizer that adopts FM +Wave Table stereophonic hybrid system that generates
up to 40 tones.
The FM synthesizer has two operation modes; “16-Voice 4 operation mode” and “32-Voice 2 operation mode” which
can be changed to each other freely (except during tone generation).
Since waveform for FM operation can be set arbitrarily, the device is able to create voices that are more complex than
by conventional devices.
Wave Table synthesizers is able to generate eight voices simultaneously, and supports 8 bit PCM and 4 bit ADPCM
data format. The sampling frequency is 48 kHz. Stream replaying is also available, realizing interchangeability with
ADPCM replay capability of MA-2.
Voice ROM and SRAM
This device stores voice parameters (GM 128 voices + DRUM 40 voices) for FM and waveform data for Wave Table in
the ROM. SRAM is used when downloading arbitrary FM voice parameter and waveform data for Wave Table. It is
also used as waveform data buffer at stream replay with PCM/ADPCM.
DAC
Converts digital signal from a synthesizer into analog signal. The data length is 16 bit.
IRQ and TIMER
This device supports FIFO, two hardware TIMERs, and interrupt output with software interrupt.

Headphone output
This device supports stereophonic analog output for the headphone. Monaural output is available.
EQ amplifier
The filter response and gain of the amplifier can be changed by adjusting external parts such as resistors and/or
capacitors.
Speaker amplifier
A speaker amplifier of which maximum out is 580 mW at SPVDD=3.6V is built in this device.
A control that adjusts the output level of the amplifier is provided in the previous stage of the amplifier.
LED and vibrator control block
LEDs and vibrator can be controlled synchronizing with a play. Control asynchronous with play is also possible.
Clock generating block
This devices supports clock input ranging from 2 MHz to 20 MHz. (Stop = 0 Hz is possible at power down.)
This block increases the frequency of inputted clock with various frequency by using PLL to create clocks with fixed
frequency that are needed in the device.
