Sound Generator IC (MIDI)
SANYO has developed ICs that, in addition to support for even more sounds, also include new
functions such as support for new standard melody formats and 3D audio.
Integrates 128-voice polyphony + PCM, 3D surround, 3D positioning* and Mobile XMF support
LC823872
Featuring
Capable of generating up to 128-voice polyphony in a full PCM sound generator
128 GM sounds + 47 drum sets + 32 sound effects sounds (conforms to GM1)
Includes a 3D surround function and a 3D positioning* function that allows the specification of positioning information
that positions the generated sound at an arbitrary position in three-dimensional space.
Supports not only the Mobile XMF new melody format but also a variety of other formats
User Customized Sound function that allows the user to register arbitrary sounds
Supports up to four songs worth of MIDI data and can play up to four channels of ADPCM (PCM) data at the same time
Includes a 4-band parametric equalizer that can provide optimal equalization for the speakers used
Supports karaoke and Java applications: JSR135, JSR2348. Supports special effects such as pitch bend, vibrato, delay,
reverb, chorus, Doppler, and compression.
Supply voltage: internal 1.5 V, I/O 1.8 to 2.8 V
Package: FBGA64 (5×5×1.2 mm)
Integrates 64-voice polyphony + PCM, 3D surround, 3D positioning, Mobile XMF support and MP3/AAC decoding
LC823553
Featuring
Capable of generating up to 64-voice polyphony in a full PCM sound generator (conforms to GM1)

*: 3D positioning function
Function that can create a realistic
impression of space even from cell
phones that cannot provide an
adequate speaker separation.
Support for 24 hours of playback

Audio Compression IC

Although previous audio playback periods have been largely limited to 3 to 5 hours, it is now possible
to achieve playing times of 24 hours or longer by adopting SANYO audio compression ICs.
MP3/WMA Decoder
LC823231
Featuring
Ultralow power (MP3: 10 mW, WMA: 15 mW)
Supported formats
- MPEG1, MPEG2, MPEG2.5 (all sampling frequencies, all bit rates)
- WMA
Digital volume and tone control circuits
Digital equalizer and audio leakage prevention functions (D/A converter based)
∆∑D/A converter and class D amplifier
PCM I/O interface
Sleep mode
Crystal oscillator frequency: 16.9344 MHz (44.1 kHz × 384)
Sampling frequencies other than 44.1 kHz supported with built-in PLL circuit
Single-Chip Audio
LC82335X
The LC82335X ICs support MP3, AAC, and AAC+.
By implementing the MP3, AAC, and AAC+ decoding functions in a hardwired structure, these ICs achieve an
ultralow power consumption that would be impossible in a DSP based structure.
Hardwired MP3, hardwired AAC, and hardwired
AAC+.
Ultralow power consumption: 10 mW
Buffer size: 10 KB
