General Description
RTS902 is a CMOS LSI designed for toys, doorbells and music boxes. It plays pr-
programmed melody and is capable of generating songs in piano effect by using the built-in
digital envelope circuit. By pushing the sequence trigger key, al songs can be played
sequentially with an Auto-Stop function. In addition, all songs can be placed in one of the
three regions and selected by pushing their corresponding direct-access keys providing the
Auto-Stop function.
