hey why don't you make two different power supplies for thembut better to use 3.3v single power supply and use atmega16A instead of atmega16 problem is solved

Click to expand...

I think the first idea is risky as the pins of the module may be overloaded by the 5v comming from the MCU pins so in addition to the two power supplies need you need several voltage level converters (buffers) to separate between the two devices

or yiu can use the second idea !
 

so if i use atmega16L only my fcpu will b 8MHz instead of 16MHz n i will get a operating voltage range of 2.7-5v...these r d only differences rite...d programming n everything else remains d same na
