Pin Configuration and Features are same!
but why Atmel usage ‪#‎ATmega48‬ and ‪#‎ATmega48P‬ two different name?

Remember that the "features" are not really the same -- P is Picopower...

http://www.atmel.com/technologie...

 

If you look at Typical Characteristics in the applicable datasheets, you will find separate sections for P and non-P variants.  I will leave it to you to determine the differences.

 

How many Mega48 models are there? ;)  The signatures might well be different. https://www.avrfreaks.net/comment...

There is now also a PB variant.

Page one of each AVR's data sheet tells all

 

Operating voltage ranges

Operating speeds

Current draws

 

They are functionally the same.  The operating parameters are the difference

Atmel provided a migration app note:

You said:

Pin Configuration and Features are same!

...but the app  note mentions:

 

Unfortunately the app note does NOT list the changes so you will need to dig them out.

 

BTW, does anyone really apply Mega48 or Mega48P these days?  PA has been out for several years.  Are non-A even being made?
