ADPCM Solid-State Recorder IC

The MSM6688 MSM6688L 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 record/playback in Microcontroller Interface mode. In the stand-alone mode, record/playback conditions CAN be selected from pins and the MSM6688 MSM6688L CAN be controlled by a simple drive Timing In the microcontroller-interface mode, record/ playback CAN be controlled by commands from the Microcontroller In the microcontroller-interface mode, the MSM6688 MSM6688L is much more flexible than in the stand-alone mode. In addition, the MSM6688 MSM6688L CAN form easily a recording and playback circuit with fixed messages 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.
