Description

UM66T/BT66 is a melody-integrated circuit. It is designed for use in bells, telephones, toys etc. It has an inbuilt tone and a beat generator. The tone generator is a programmed divider that produces certain frequencies. These frequencies are a factor of the oscillator frequency. The beat generator is also a programmed divider that contains 15 available beats. Four beats of these can be selected.

There is an inbuilt oscillator circuit that serves as a time base for the beat and tone generator. It has a 62-notes ROM to play music. A set of 4 bits controls the scale code while 2 bits control the rhythm code. When power is turned on, the melody generator is reset and the melody begins from the first note. The speaker can be driven by an external NPN transistor connected to the output of UM66.
