CF1156 series

Melody LSIs

OVERVIEW

The CF1156 series are CMOS melody LSIs with built-in LED driver that, together with a battery and piezo-

electric buzzer, operate in one of 3 melody modes determined by input level or bonding options. They also fea-

ture 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.
