Development board for AT91SAM7X512... Or other

Hi,

I’m looking for a development board for the AT91SAM7X512. Sparkfun has one but it’s quite complicated, thus expensive for what I want to do.

Ideally I would like to buy a header board, like the ones available for the LPC families, and available for about $50.

Any idea where I can find such a development board?

Thanks!

Does it have to be the 512? You can get the 256 header board.

If you seriously want a header board, you can get the 256 one and a separate 512 chip. Desolder the 256 and put on the 512. They are pin compatible. They might be a little much for your soldering skills, though.

It has to be the 512, as it has 128k of RAM. This is the reason why I’m switching from NXP to Atmel, I need the 128k of RAM.

Any other (ARM7) microcontroller that may satisfy this requirement, with 100 pins of less QFP? Ideally I’d like to stick to the ARM7 family, as I already have a JTAG for it.

No other Arm7 has a similar RAM quantity. You can interface external SRAM or SDRAM to other ARM7s however.

AT91SAM7S512 only has 64K of RAM. Same as the AT91SAM7S256.

Your only option is external SRAM.
