ML22Q553-NNNMB/ML22Q553-xxxMB

4-Channel Mixing Speech Synthesis LSI with Built-in FLASH ROM for Automotive

GENERAL DESCRIPTION

The ML22Q553-NNN and ML22Q553-xxx are 4-channel mixing speech synthesis LSIs with built-in FLASH

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. 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.
