I've seen a microcontroller (don't remember the exact part number at the moment,) that doesn't have XTAL pins.

It was an 8-pin MCU - it didn't have any clock input pins on the device.

Has anyone has worked with such devices? How do those devices work without a clock, and with only power. How does the device start working?

I understand that there are internal oscillators that would help, but just not able to understand how the device would start up. Like, how would it be for programming and other stuff?

Are there any Microcontroller'smicrocontrollers that do not require anyan external clock source for working?

I've seen an MCUa microcontroller (don't remember the exact part number at the moment),) that doesn't have XTAL pins.

Like, itIt was an 8-pin MCU. Like, - it didn't have any clock input pins on the device.

Just want to understand, ifHas anyone has worked with such devices? In that case, howHow do those devices, start to work? Like, without a clock, and with only power, how. How does the device start working?
