GENERAL DESCRIPTION
MSM9831 is a PCM-based Voice Synthesis LSI (Playback only) with on-chip 384Kbit Mask ROM,
D/A Converter and Low-Pass Filter.
Serial input interface for an external MCU makes MSM9831 a better choice for size-critical
applications with less wiring pin-count in small foot-print packaging.
