ML2215
Speech Synthesizer plus Music LSI with On-Chip 3 Mbit Mask ROM
This version: May 2001
GENERAL DESCRIPTION
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.
