MSM6588/6588L
ADPCM Solid-State Recorder (for Serial Registers)
This verMsiSoMn:6F5e8b8./16959898L
Previous version: May. 1997
GENERAL DESCRIPTION
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 like a tape recorder.
The MSM6588/6588L has a stand-alone mode and a microcontroller interface mode. In stand-
alone mode, record or playback can be selected via a pin and it is possible to control the MSM6588
at a simple drive timing. In microcontroller interface mode, record/playback can be controlled
by commands from the microcontroller, the MSM6588/6588L is much more flexible in
microcontroller mode than in stand-alone mode. 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.
