CF1155 series

Melody LSIs

OVERVIEW

The CF1155 series are CMOS melody 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 func-

tion 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 applica-

tions including greeting cards and toys.
