LSIs that, together with a battery and piezoelectric buzzer, operate in one of 3 melody modes determined by input level or bonding options. They also feature an oscillator stop function in non-play mode and a variable pull-down resistance function that responds to input levels in order to reduce power consumption, reduce cost, and extend battery life, making them ideal in a wide range of applications including greeting cards and toys. FEATURES s s s s s s Requires few external components 1.2 to 3.
