4-Channel Mixing Speech Synthesis LSI with Built-in FLASH/MASK ROM
GENERAL DESCRIPTION
The ML22Q563-NNN, ML22Q563-xxx and ML2256X-xxx are 4-channel mixing speech synthesis LSIs with
built-in FLASH/MASK ROM for voice data. These LSIs incorporate into them an HQ-ADPCM decoder that
enables high sound quality, 16-bit D/A converter, low-pass filter, and 1.0 W monaural speaker amplifier for
driving speakers. Since functions necessary for voice output are all integrated into a single chip, a system can
be upgraded with audio features by only using one of these LSIs.
