Description

The Electronic Component Model L2213-317J is an ADPCM-based Speech Synthesizer LSI with on-chip 1.5 Mbit Mask ROM. It is widely used in products that require speech and music playback capabilities. The LSI has a built-in Music Generator circuit that can generate music by automatically acquiring user-defined musical notes data from the ROM. With a 12-bit D/A Converter and Low Pass Filter, it is easy to build a message and music playback sub-system by simply adding an external speaker and driving amplifier.
