The ML22594-xxx is 4-channel mixing speech synthesis LSIs with built-in 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, 1.0 W monaural speaker amplifier for driving speakers , and over-current detectible function for Speaker Pins. And the high quality and a long time sound regeneration is possible by using the voice regeneration which the outside ROM was used for.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.
