-2-
When only 2-operator tones are used: up to 16 voices can be generated simultaneously.
When only 4-operator tones are used: up to 8 voices can be generated simultaneously.
Compatible with stereophonic sound generation.
Volume control
Channel volume, master volume, expression, and pan pot control in individual channels
Sequencer is built in.
Can interpret Mobile Multimedia Format directly.
Equipped with four systems of 96 FIFOs for sequence data
Supports direct access that directly controls FM synthesizer.
Supports key control with half an octave higher and lower.
ADPCM reproduction function
Equipped with ADPCM decoder with 4 bits, 1 channel
Supports two kinds of sampling frequency, 4 kHz and 8 kHz.
Sequencer is built in.
Equipped with 348 byte FIFO for ADPCM data and 32 byte FIFO for sequence data
Supports direct access that directly controls ADPCM section.
Speaker amplifier and equalizer circuit
Output of speaker amplifier: 550 mW when SPVDD=3.6 V, or 400 mW when SPVDD=3.0 V
Balanced input speaker amplifier provides low ripple
Built-in equalizer circuit corrects the difference of frequency response among the speakers and forms of
bodies.
Interface
4 wire serial interface or 12 wire parallel interface can be selected.
Others
PLL is built-in to support master clock input in 2 MHz to 20 MHz range.
Provided with a circuit for controlling on/off of LEDs and vibrator. These can be operated synchronous with
the play data.
Provided with a stereophonic analog output terminal for headphone
16 bit stereophonic D/A converter is built in.
Supports power down mode. (Typical current: 1 A or less)
Power supply voltage
The power supply includes two power supply sub-systems, analog power supply devoted to speaker amplifier
and power supply for other sections.
The power supply for the speaker amplifier (SPVDD) supplies voltages in the range 2.7 V
~ 4.5 V (Typ 3.6 V),
and other power supplies (VDD) voltages in the range 2.7 V
~ 3.3 V (Typ 3.0 V).
32-pin plastic QFN.
