other parts : ML2215  ML2215-XXXMA 

Oki Electric Industry

The ML2215 is an ADPCM-based Speech Synthesizer LSI with on-chip 3 Mbit Mask ROM for storing multiple speech data. In addition, the LSI has a built-in Music Generator circuit that can generate music by automatically acquiring user-defined musical notes data from the ROM. The ML2215 contains a 12-bit D/A Converter and Low Pass Filter, and enables a user to readily built a message and music playback sub-system by simply adding an external speaker and driving amplifier.
