FEATURES
• PCM sound generation method provides realistic sound reproduction
• Built-in digital signal processor for MP3/AAC decoder
• Built-in real-time wide surround function
(for all sources including PCM sound generators, MP3/AAC sources, and audio serial input)
• Up to 68 tones (= 64 polyphonic tones + 4 ADPCM) can be played at the same time, so an abundant variety of tunes can be generated and played
• Supports ADPCM playback. Simultaneous playback with MIDI is also enabled
• Includes a high-performance D/A converter with 16-bit resolution
• Supports five sampling frequency modes: 8 kHz, 16 kHz, 32 kHz, 44.1 kHz, and 48 kHz (ASI and MP3/AAC
decoder)
• Provides audio serial I/O interface (16 bits). The serial data input frequency is variable between 32 fs and 64 fs (during slave mode). Supported formats are right-justified, left-justified, and IIS.
• Includes function for mixing MIDI/ADPCM/MP3/AAC signals and audio serial input signals (only fs = 32 kHz sampling is supported).
• Supports 8-bit parallel interface. The host CPU is connected via an 8-bit parallel interface when PS = 0.
• Supports SPI. The host CPU is connected via a 3-wire or a 4-wire serial peripheral interface (SPI) when PS = 1.
• Supports three outputs modes (single end MONO, differential MONO, and STEREO)
• Includes output control functions for vibrator and LED
• Built-in PLL, so various types of input clocks can be supported
• Supports two I/O power supply voltages: 1.8 to 3 V (supports only digital pins)
