Hi Sunil It is manufacturer’s product ID. C1 is used to decouple power supply to avoid inter-modulation between output and IC. If you get a distorted sound you can add 100uF electrolytic capacitor in parallel to C1

is it possible to store our own created music into um 66 if yes , how to store it… what circuit can be used. if not can any one tell me a nice way to “Design a circuit to create, play and save ringtones”

Like Admin has stated, UM66 is designed and manufactured with those melodies. You can not reprogramme it. You need a voice recorder circuit interfaced with a amplifier circuit.

It is not possible to store our own music in UM66.
I will add a voice recorder circuit soon.
