ML22Q573-NNNMB/ML22Q573-xxxMB/ML2257X-xxxMB FEDL2257-08 Issue Date: Aug. 8, 2017 4-Channel Mixing Speech Synthesis LSI with Built-in FLASH/MASK ROM for Automotive GENERAL DESCRIPTION The ML22Q573-NNN, ML22Q573-xxx and ML2257X-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.
