IC UM66 PDF

UM66 is CMOS technology melody integrated circuit especially used in to give the output from speaker, when we reset the circuit UM66 will play the melody. The following schematic is for UM66 or BT66 musical IC. You need very few components to make this circuit. Pin configuration for UM66 is. Here is one listing from China for the UM66, and another one from France. Some IC become obsolete and may not be available in market.

How to use UM66 or BT66 Musical IC | BuildCircuit – Electronics

Here is one listing from China for the UM66, and another one from France. There is an inbuilt oscillator circuit that serves as a time base for beat and tone generator.

Speaker or buzzer 5. Note that there are some unscrupulous semiconductor vendors on eBay so be careful, I would always buy from somewhere like Digikey, Mouser, Farnell, etc if you can I had a quick look but couldn’t see anything particularly suitable.

Four beats of these can be selected. Infrared based music transmitter and receiver. Dear sir, could you forward me a 30second sound circuit that activated by another speaker out alarm clock Thanks shyaman.

The UM66 IC looks like a transistor with 3 terminals but it is a complete jc tone generator with a tune and they come in variety of different tunes. Data sheet of UM66 is there in the datasheet section of the site. So I’ll suggest changing your schematic to some other doorbell circuit by searching on google: What other ICs could I possibly use in this circuit?
