Recording and 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 MSM9841 is a mono/stereo record and playback LSI with a built-in 1K bit FIFO for easy

interface with external systems or non-semiconductor memory. It utilizes multiple record and

playback modes, including the new ADPCM2 algorithm, which allows for even higher quality

sound reproduction. The record and playback functions of the MSM9841 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 record and playback:

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

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

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

• For the built-in ADC, set the sampling frequency at 16 kHz or less.

• DMA interface support

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

• Built-in 14-bit A/D converter

• Built-in 14-bit D/A converter

• Built-in low pass filter (LPF) : (input side: analog LPF)

: (output side: digital LPF)

• Power supply voltage: 2.7 V to 5.5 V

• Package:

56-pin plastic QFP (QFP56-P-910-0.65-2K) (Product name: MSM9841GS-2K)

*note 32 kHz, 22.05 kHz and 44.1 kHz are available only for playback.
