MSM9831-xxx - VOICE SYNTHESIS LSI with on-chip 384Kbit MASK ROM

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.

Key Features

  • 8-bit OKI Non-Linear PCM Algorithm.
  • Sampling Frequency (Selectable on each phrase) 4.0/5.3/6.4/8.0/10.6/12.8/16.0 kHz.
  • On-chip Mask ROM Capacity : 384 Kbits.
  • Maximum Playback Time Length 12.0 sec. at fsam = 4.0 kHz 6.0 sec. at fsam = 8.0 kHz 3.0 sec. at fsam = 16.0 kHz.
  • Clock Oscillation 3.5 to 4.5 MHz (Ceramic Oscillation) 3.5 to 17 MHz (External Clock).
  • User definable Phrase Control Table function.
  • Maximum number of Phrases : 31 p.
