Hi Someone asked me to help him with AT91RM9200 and AT91RM9200-EK kit. I have gnu toolchain with gcc "3.4.3". I plan that we will run programs directly on that processor - without any kind of operating systems (linux or winCE). I'm looking for project samples for this board. Are there in the internet available any project free samples? I need informations about memory addressing - whe...

We are designing a microcomputer based on the Atmel AT91RM9200 controller. We are gong to give it 128Mb of SDRAM, 4M X 32. I am trying to decide whether to use 2 x 4M x 16 or 1 x 4M x 32. The reference design uses 16 bit wide memories, which appear to be slightly cheaper than the equivalent 32 with perhaps more manufactureres. What do people feel, what are the advantages of each, easier layo...

Just beginning a new design here, built on the AT91RM9200. I am searching for RoHS-compliant components that will be available now and hopefully well into the future. First up is a enet PHY. AMD says that they have successfully tested these PHY chips: Intel LXT971A, Davicom DM9161E, AMD Am79C874. However, the chip that seems to be most readily available (and low power) is the National DP...
