FEATURES

• PCM sound generation method provides realistic sound reproduction

• Up to 68 tones can be played at the same time, so an abundant variety of tunes can be generated and played

• Implements ADPCM decode functions. 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 only)

• 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 PCM sound source output signals and audio serial input signals (only fs = 32 kHz

sampling is supported).

• Includes a surround function that uses real-time processing (to produce surround effects based on real-time processing for all sources including PCM sound sources and audio serial input).

• Host CPU is connected via an 8-bit parallel interface.

• Includes output control functions for vibrator and LED

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

• I/O power supply voltage: 3 V (Digital pins support 3 V and 1.8 V.)

• Power supply voltages: DVDD: 1.425 to 1.575 V, EVDD: 1.71 to 3.3 V, AVDD: 2.85 to 3.15 V,

AVDD-P: 2.85 to 3.15 V

• 65-pin tape FBGA package (6 × 6 mm body size, 0.5 ball pitch)
