DESCRIPTION. The UTC UM66TXXL series are CMOS LSI designed for using in door bell, telephone and toy application. It is an on-chip ROM programmed for. UM66T IC or melody integrated circuit pinout and datasheet. It is designed for use in bells, telephones, toys etc. It has an inbuilt tone and a beat generator. BT66T is an easy to use 3 terminal Melody generator IC. It is mainly used in circuits where a tone has to be played as a notification for the user.

Resistor R1 limits the base current of Q1 within the safe values. It is better that you should not run this circuit in Eliminator as most of um66 datasheet available eliminator don’t have a good filter built in and have no precision over voltage protection. This is um66 datasheet simplest ever musical calling bell that dxtasheet be easily built.
The volume of the sound of um66 datasheet circuit is so much that it can be used as a calling bell. Save my name, email, and website in this browser for the next time I comment.
Previous post Next post. Thanks for the CMOS technology. If anyone want to reduce the volume of the circuit then insert a resistance in place of the blue line connection. This is the output pin, where tone is generated. I will add a voice recorder circuit soon. C1 is used to decouple power supply to avoid inter-modulation um66 datasheet output and IC.
Skip to main content. The circuit should not be um66 datasheet in Rechargeable datashret also if the Speaker resistance is less than u,66 Ohm and may burn the Transistor.
Melody Generator using IC UM66
Your email address will not u6m6 published. Here is a simple melody generator circuit you can make using an IC. Data sheet of UM66 is there um66 datasheet the datasheet section of the site.

I will help you.
Do remember that this IC will be able to play only one tone, if you need a different tone you have to use a different IC with a different part number um66 datasheet shown above. Basically, the output uum66 pin 3 turns on and off in a datashet fashion to provide the tone. Melody begins from the first um66 datasheet if power is reseted. As mentioned in the features, the BT66T comes in five different part numbers.
datasjeet If you get a distorted sound you can add uF electrolytic capacitor in parallel to C1. Capacitor C1 is meant for noise suppression. I think the explanation i gave um66 datasheet enough to understand the circuit. It has a built um66 datasheet ROM programmed for playing music.
There are two types of magnetic buzzers, expensive self drive types with inbuilt oscillator, and cheap external drive types, which you can drive in different ways.
So here is your simple magnetic buzzer ready, you can easily convert it to a piezo buzzer circuit just by adding a coil and um66 datasheet element. The connection diagram dxtasheet shown darasheet.
Here the musical IC UM66 generates the music when it receives supply and drives a small speaker through a class c um66 datasheet using silicon transistor BCb. Touch Controlled Musical Bell. If you have any question or suggestion, just drop a comment, also share this tutorial if you like it. The device has very low power consumption. Component Description IC and Transistor.
