¡ Semiconductor VOICE SYNTHESIS LSI with on-chip 384Kbit MASK ROM
This version: Sep. 1999 MSM9831-xxx
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.
