It has a built in ROM programmed for playing music. Each part um66 datasheet has the datashest to play a different type of tone. We have already learnt how Zener can um66 datasheet used as Regulator and how the Zener resistor value R1 can um66 datasheet calculated. Melody begins from the first note if power is reseted.

They can make reasonably loud sound at as low as 1. Do remember that this IC will be able to play only one u66, if you need a different tone you have to use a different IC with a different part number as shown above.
