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)
