The CF(SM)1155 series are CMOS melody LSIs that, together with a battery and piezoelectric buzzer generate sound. An oscillator stop function in non-play mode and a variable pull-down resistance function reduce power consumption and extend battery life, making them ideal in a wide range of applications including the hold sound for telephones, greeting cards and toys, as well as white goods
