The AT91RM9200's ARM9 core is surrounded by a pair of 16-kbyte caches, USB 1.1 host and device interfaces, 10/100T Ethernet, four USARTs, a serial peripheral interface, 16 kbytes of SRAM, and a 128-kbyte boot ROM. Applications are typically downloaded from Atmel serial DataFlash. There's an interface for external SDRAM, Burst Flash, Compact Flash, and Smart Media storage. This interface can handle Atmel's AT77C101 fingerprint scanner as well. The SSC interface can be connected to an audio digital-to-analog converter. There are plenty of GPIO ports, too. Debugging support includes a JTAG interface and ARM ETM trace support.

Pricing for the AT91RM9200 starts at $12. It comes in both PQFP208 and BGA256 packages. A software development kit for the chip along with Green Hills (www.greenhills.com) software is available for $5000. Linux support will be available from Atmel (www.atmel.com).

I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.

I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
