I´m quite interested in the AT91SAM7X-128/256/512 !

Unfortunately I could´nt find a datasheet on the web, is there one already ?
Is there a evaluation board with this chip available or planed ?

Hi,

unfortunately not yet. This device is planned for the second quarter of 2005 and the datasheet are under construction. The preliminary datasheet should be available by the end of this month. For info, there will be an evaluation board as well.

Hope to help.

Not full datasheet, only pins description?

They are supposed to be pin compatible with the AT91SAM7S64 which has a full (preliminary) datasheet.

I expect these devices to be very similar to the AVR line in that a simple review of register descriptions and recompile are all that is needed to go from one device to another. In this case, the register descriptions will probably be the same anyway.

For example, with the Atmel AVRs, I can go from an Atmega64 to an Atmega128 (and back) with the change of a #define and a recompile. The only major differences between the chips is flash/eeprom size.

You should be able to get started with the AT91SAM7S64 datasheet.


Hope this helps.

Since the core and peripherals are mostly the same, you should be able to run a SAM7S project on a SAM7X with just a retarget compile. Note though that the SAM7S is in the 64-QFP and the SAM7X is in a 100-QFP.
