What kind of flash unit is it?

I see that the Yashica 230-AF has a really small flash unit. I'm wondering if this flash unit is an exception made specifically for this particular camera model, or if it's a type of flash unit that's compatible with most analog cameras. I'm asking because I get lost in the terminology of flash units and can't figure it out on my own. If it were a distinct type and not just a one-off invention, I would like to buy it for my non-yashica camera, but I need to know its name first.

Thank you
