External Memory Type
The ML2253x series is 4 channels mixing speech synthesis LSIs for automotive-grade with built-in serial audio interface, available in flash memory and external memory types.
Features include HQ-ADPCM, 16bit D/A converter, and low-pass filter for achieving high sound quality, along with an integrated 1.0W monaural speaker amp that enables direct speaker drive.
A failure detection function is also built in capable of detecting malfunctions.
All functions necessary for audio output are integrated on a single chip, making it possible to easily add voice functionality by simply adding this LSI.
