MSM6588/6588L
ADPCM Solid-State Recorder (for Serial Registers)
This version: Jan. 1998
MSM6588/6588L
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 similar to a tape
recorder.
The MSM6588/6588L has a stand-alone mode and a microcontroller interface mode. In stand-
alone 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.
