Do exit in the world microcontrollers with simultaneos presence of bit space and A/D converter ? That is the question.
Yes, plenty of them.
The device database will help you find them.

"bit space"
What do you mean by that?
Are you talking specifically about the bit-addressable area(s) of the 8051 archtecture?
Exactly so. Bit-addressable area - it is more right expression.
In that case, search the device database for 8051-family devices with built-in ADC.
