MSM6688 General Description
The MSM6688/6688L is a "solid-state recorder" IC developed using the ADPCM method. Byexternally connecting a microphone, a speaker, a speaker drive amplifier, and a dedicated registero 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 interfacemode.
The MSM6688L supports 3 V operation and controls recording/playback in microcontroller interfacemode.
In the stand-alone mode, recording/playback conditions can be selected by pins and the MSM6688/6688L can be controlled by a simple drive timing. In the microcontroller interface mode, recording/playback can be controlled by commands from the microcontroller. In the microcontroller interfacemode, the MSM6688/6688L is much more flexible than in the stand-alone mode.
In addition, the MSM6688/6688L can form easily a recording and playback circuit with fixedmessages by connecting serial registers and serial voice ROMs as external memories.
Note: This data sheet explains a stand-alone mode and a microcontroller interface mode, separately.
