The AT91SAM7SE subfamily has an EBI. I would select this one over the AT91FR if
the EBI is the main reason for choosing the AT91FR.
Ewout Boks > Atmel has a lot of online sample code for each of
these chips. I would suggest downloading these and searching for appropriate
source code.

The main difference is the sam7 has no external memory bus. The other, older
family can access external flash or sram, though you might need a dram
controller if you want dynamic ram. The sam is really a system on a chip, while
the 40162s lacks many of the peripherals. Internally they are both ARM7
cores.
Atmel has a lot of online sample code for each of these chips. I would suggest
downloading these and searching for appropriate source code.

What is the difference between AT91sam and AT91FR as i am using AT91FR40162S .
As i am a fresher for this so can any body help me for some basics like
1) which start.s file should i use as i am using Keil tool so there is one
start.s file which is under Atmel folder?????
2) wht all changes i need to do in start.s file. ?????
3) where i can specify my C code entry point in start.s file
I know many people here will be highly experienced. So please give me the
answers for my there simple questions.
Thnx in advance
