CF1155 series Melody LSIs
CF1155 series CMOS melody LSIs that, together with battery piezoelectric buzzer, operate melody modes determined input level bonding options. They also feature oscillator stop function non-play mode variable pull-down resistance function that responds input levels order reduce power consumption, reduce cost, extend battery life, making them ideal wide range applications including greeting cards toys.
Requires external components 3.6V wide operating voltage range power consumption melody modes (bonding option) Oscillator stop function non-play mode Power saving pull-down resistor built-in oscillator circuit Power-ON initialization function connections Wide pitch dynamic range Chip form

FUNCTIONAL DESCRIPTION
Melody Modes
CF1155 series melody mode determined bonding options levels mode control inputs When either both HIGH (VDD), corresponding melody mode selected shown following table.

Power-save Function
shown preceding timing diagrams, oscillator stops during non-play mode pull-down resistance value changes response both HIGH-level LOW-level inputs (power-save pull-down resistor) reduce power consumption extend battery life. Non-play oscillator stop function When melody play ends, regardless state either OSH, internal oscillator stops placed standby state. this state, current consumption, including input pull-down resistor current (IIH max), does exceed 3.3µA. Power-save pull-down resistor resistance input pull-down resistor changes response input voltage. pulldown resistance when input HIGH, pull-down resistance 270k when input LOW. Furthermore, light-dependent resistor (CdS) cell employed switch (the pull-down resistance maximum when resistance minimum (light) pull-down resistance minimum when resistance maximum (dark)), combined resistance increased, decreasing current consumption.
