VOICE SYNTHESIS LSI with on-chip FIFO Memory

• General Description

MSM9844 is a Voice Synthesizer LSI with on-chip FIFO memory.

A newly developed synthesis algorithm, OKI ADPCM2, promises superb sound quality. The LSI is fully

controllable from an external CPU via 16/8-bit bus interface.

MSM9844 is an ideal choice for application systems where such non-microchip data storage as CD ROM is

used..

• Features

• 16/8-bit Bus Interface

• On-chip FIFO Memory Capacity : 1024 Bits 23 ms Buffering

When Sampling Frequency at 8.0 kHz, 4-bit ADPCM and Monaural Playback selected

• Synthesis Algorithms for User's Selection

4,5,6,7,8-bit OKI ADPCM2

4-bit OKI ADPCM

8/16-bit Straight PCM

8-bit OKI Non-Linear PCM

• Oscillation Clock Frequency: 16.9344 MHz / 24.576 MHz

• Sampling Frequency:

11.025 kHz, 22.05 kHz, 44.1 kHz at fOSC=16.9344 MHz

4.0 kHz, 6.4 kHz, 8.0 kHz, 12.8 kHz, 16.0 kHz, 32.0 kHz, 48.0 kHz at fOSC=24.576 MHz

• Sound Level Control (8 levels, 0dB ~ -21dB)

• Built-in 14-bit D/A Converter

• 3 types of Serial Interface for External DAC

• Sampling Rate Conversion Function

• Packaging: 56-pin Plastic QFP (QFP56-P-910-0.65-2K)
