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 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, all songs can be played sequentially with an AutoStop 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.
