Yes,  the AY-3-1015D is a UART.  It's the ony datasheet that I have that
starts with AY-3 and that why I know.  The only prob with this data sheet is
that it doesn't tell me the name of any manufacture.

If you want a copy of this DS then send me your address (postal) and I'll
send you a photo copy as this ones in a book.
