As a single-chip peripheral, only few external components are required. A new design is as easy as is implementation into existing MCU controlled digital systems also considering the wide power supply range. Development of speech codes is made easy, too with a choice of PC based development tools. The LSIs are particularly suited for small devices for the purpose of providing voice guidance, feedbacks and similar.
Cellular phones are one of the targets.
Simple design-in, fast development of speech codes. Precision converters and high grade filters produce high quality sounds. Cost efficient for both low and high end applications.
