got the details of micro-controller from datasheet. 8952 can not drive so many LED at a time.
------------------
Under steady state (non-transient) conditions, IOL must be externally limited as follows:
Maximum IOL
per port pin: 10 mA
Maximum IOL
per 8-bit port:
Port 0: 26 mA Ports 1, 2, 3: 15 mA
Maximum total IOL for all output pins: 71 mA

That's it! Not so hard, eh?!

so i need to use some kind of drive circuit has to be used.

correct.

Any suggestion regarding the LED driver circuit.

How about looking at what all the hundreds of other LED cube projects on the interweb use...?
