E2D0097-19-94 ¡ Semiconductor MSM9831-xxx ¡ 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. 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 phrases 10-bit current-output-type D/A Converter A built-in LPF Power Supply Voltage : +2.0 to +5.5 V (External Clock) +2.5 to +5.5V (Ceramic Oscillation) Package: 8-Pin SOP Package (SOP8-P-250-1.27-K) (Product name: MSM9831-xxx MA) COMPARISON TABLE WITH MSM9802 MSM9831 Mask ROM Capacity Interface Oscillation Max.
