1 / 8 page CF1156 series SEIKO NPC CORPORATION —1 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. FEATURES I LED direct drive I Requires few external components I 2.0 to 3.6V wide operating voltage range I Low power consumption I 3 melody modes (bonding option) I Oscillator stop function in non-play mode I Power saving pull-down resistor built-in I RC oscillator circuit I Power-ON initialization function I 2 VSS pad connections I Wide pitch dynamic range (G3 to D7) I Chip form ORDERING INFORMATION Device Package CF1156 Chip form |
