E2D0025-39-23 ¡ Semiconductor ¡ Semiconductor MSM6588/6588L ADPCM Solid-State Recorder (for Serial Registers) This version: Feb.
1999 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 like a tape recorder.
The MSM6588/6588L has a stand-alone mode and a microcontroller interface mode.
In standalone 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.
