Mini Mobile Robot Controller(MC40A)
if i want to control 4 motor .. can Mini Mobile Robot Controller(MC40A) do it... i notice this microcontroller can support 2 motor.. other 2 motor , i think to build their own driver...

other what is mean by Free IO pins are extended out for further development.... how many input that their have...

I have 1 MC40A from last year 1 cent promotion :)

The on board Driver is L293B, you should be able to control up to 1A of current for motor. Extra 2 motor you need to use the free IO. The free IO means the part where you see the header pin at prototyping area, near to LCD.

If you look at the User's Manual clearly, it do state that the pins under the prototyping section are the free IO pins.

Also, check the schematic.
