Playback LSI with Built-in FIFO

This document contains minimum specifications. For full specifications, please contact your

nearest Oki office or representative.

GENERAL DESCRIPTION

The MSM9842 is a mono/stereo playback LSI with a built-in 1K bit FIFO for easy interface with

external systems or non-semiconductor memory. It utilizes multiple playback modes, including

the new ADPCM2 algorithm, which allows for even higher quality sound reproduction. The

playback function of the MSM9842 is controlled by an MCU via 8/16-bit bus interface.

FEATURES

• 16/8-bit bus interface support

• FIFO capacity: User-definable (256/512/1024 bits)

(buffering time of 32 ms when using 8 kHz sampling frequency, 4-bit ADPCM2/ADPCM, and

in monaural playback)

• Supports four compression algorithms for playback:

4, 5, 6, 7, 8-bit ADPCM2; 4-bit ADPCM; 8; 16-bit PCM; and 8-bit Nonlinear PCM

• Sampling frequency: 4.0 kHz, 6.4 kHz, 8.0 kHz, 12.8 kHz, 16.0 kHz, 32.0 kHz (fosc=4.096 MHz)

• Sampling frequency: 22.05 kHz, 44.1 kHz (fosc=5.6448 MHz)

• DMA interface support

• Volume control (8 steps: 0 dB to –21 dB)

• Built-in 14-bit D/A converter

• Built-in low pass filter (LPF)

• Power supply voltage: 2.7 V to 5.5 V

• Package:

56-pin plastic QFP (QFP56-P-910-0.65-2K) (Product name: MSM9842GA)
