The MSM6588/6588L is a "solid-state recorder" IC developed using the ADPCM method. By externally connecting a microphone, a speaker, a speaker amplifier and a serial register or other Memory device to store ADPCM data, it can record and playback voice data similar to a tape recorder.
The MSM6588/6588L has a stand-alone mode and a microcontroller interface mode. In standalone mode, record/playback can be selected from a pin and it is possible to control the MSM6588 by a simple drive timing. In microcontroller interface mode, record/playback can be controlled by commands from the microcontroller in microcontroller mode, the MSM6588/6588L is much more flexible than in stand-alone operation. In addition, recording and playback with fixed message are easily implemented by connecting a serial voice ROM.
The MSM6588 and the MSM6588L support 5 V and 3 V operation respectively.
