The SC9200A/B tone generators are designed for C interfaces. They can be instructed by a C to generate 16 dual tones and 8 single tones from the DTMF pin. The SC9200A provides a serial mode whereas the SC9200B contains a selectable serial/parallel mode interface for various applications such as security systems, home automation, remote control through telephone lines communication system, etc.
