External Memory Type
The ML2253x series of automotive-grade 4 channels speech synthesis LSIs with built-in Flash memory are optimized serial audio interfaces and voice data.
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.
