RTS902 NATURAL SOUND EFFECT MELODY GENERATOR Features - Operating Voltage range: 2.4V to 5.0V Low power consumption 256-note ROM memory RC oscillator with an external resistor 1 sequence trigger key and 3 direct access keys are provided to select which song is to be played. Built-in on-the-chip envelope modulator Direct-drive speaker and programmable LED flash Provided PEN pin for drive motor Typical oscillator frequency: 128 KHz Power-ON Reset; melody begins from the first note. General Description RTS902 is a CMOS LSI designed for toys, doorbells and music boxes. It plays prprogrammed melody and is capable of generating songs in piano effect by using the built-in digital envelope circuit. By pushing the sequence trigger key, all 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.
