MSM9841 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.
MSM9841 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
• 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)
• 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.
