Features
- PCM sound generation method provides realistic sound reproduction.
- Up to 68 (= 64 polyphonic + 4 ADPCM) tones can be played at the same time, so an abundant variety of tunes can be generated and played.
- Implements ADPCM playback functions. Simultaneous playback with sound generation is also available.
- 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 when PS = 0.
- Host CPU is connected via a 3-wire or 4-wire Serial Peripheral Interface (SPI) when PS = 1.
- Includes output control functions for vibrator and LED.
- PLL is built-in, so various types of input clocks can be supported.
- Digital I/O supports EVDD = 3 V to 1.8 V.
- 電源電圧 DVDD: 1.425～1.575 V, EVDD: 1.71～3.3 V, AVDD: 2.85～3.15 V, AVDD_P: 2.85～3.15 V
- 65-pin tape FBGA package (6×6 mm body size, 0.5 ball pitch).
