Features

  • Wide operating voltage range: 2.4V to 5.0V - Low Stand-by current - 768-note ROM memory - Direct LED drive, where LED flash is programmable. - Typical oscillator frequency: 128 KHz - Built-in digital envelope - 1 sequence trigger key - Audio output drives speaker directly. - Power-ON Reset; melody begins from the first note. General Description RTS903 is a CMOS LSI designed for toys, doorbells, music boxes, and melody clocks/timers. It is designed to play pre-programmed melody and is capable of generating dual-tone melody and natural sounds in piano effect. By pushing the sequence trigger key, all songs are sequentially selected and played with an Auto-Stop function. In addition, RTS903 provides PLED and PEN pins to drive LED and the motor. The blinking of LED is programmable to meet different user applications.
