DESCRIPTION

The

µPD9971 is a sound generator LSI for ringer melodies for mobile phones that are equipped with 3D positioning

surround functions.

FEATURES

• PCM sound generation method provides realistic sound reproduction

Contains 32 kHz sampling Wavetable, it include 128 GM tone and 47 drum set and 32 effect tone.

A richer tone is achieved by using 2 Wave a tone.

The wave and the parameter can be downloaded, and the sound-making not limited to a fixed tone is

possible.

Can play up to four melodies because of four MIDI

TM ports that are embedded in the sound generator core.

The port for a real-time control of MIDI that assumes karaoke and the JAVAapplication program is installed.

Contains a digital parametric equalizer for equalizing speakers.

The function for a low output of the level to always enable the reproduction in the vicinity of the maximum

volume is built into.

Various sound effects (pitch pipe bend, vibrato, Delay, reverberation, chorus, Doppra, and compressor) can

be achieved.

Supports MOBILE-XMF.

• Contains real-time-processing 3D positioning surround functions

The effect of the sound that the sound source moves three-dimensionally by the digital signal processing

can be achieved.

The stereophonic effect with the extension can be obtained by the digital signal processing.

The programmable solid sound parameter is installed, and the best setting is possible in the case and the

speaker arrangement etc. of the cellular phone.

When the headphone is used, the stereophonic effect can be obtained.

• Includes a high-performance D/A converter with 16-bit resolution

Supports five sampling frequency (fs) modes: 8 kHz, 16 kHz, 32 kHz, 44.1 kHz, and 48 kHz

• Provides an audio serial I/O interface (16 bits).

The serial data input frequency is variable from 32 fs to 64 fs (during slave mode).

Supported formats are right-justified, left-justified, and IIS

• Provides an external serial input/output interface for the sound generator

• Provides stereo line output for audio

• Supports 8-bit parallel interface or 3 or 4-wire serial interface (SPI).

• Output control functions for vibration and LED.

• Built-in PLL, so various types of input clocks can be supported.

• Contains a regulator for digital power supply (DVDD).

The mark

shows major revised points.
