GENERAL DESCRIPTION
The MSM6688/6688L is a “solid-state recorder” IC developed using the ADPCM method.
By externally connecting a microphone, a speaker, a speaker drive amplifier, and a dedicated register to store ADPCM data, it can record and play back voice data in a manner similar to a tape recorder.
The MSM6688 supports 5 V operation and has a stand-alone mode and a microcontroller interface mode.
The MSM6688L supports 3 V operation and controls recording/playback in microcontroller interface mode.
In the stand-alone mode, recording/playback conditions can be s...
