8-Bit MCU Packs Encryption Hardware

Oct. 27, 2005

The 8-bit Rabbit 4000 leaps over the current Rabbit 3000. Developed by Rabbit Semiconductor, this low-EMI (under 10 dB µV/m at 3 m) device adds a host of new instructions with support for 16- and 32-bit registers, hardware encryption acceleration,

Its major architectural improvements include the ability to control memory and I/O access. The forthcoming RabbitSys real-time operating system and Dynamic C development environment will take advantage of this enhanced protection system.

The chip will be the basis for a line of embedded modules that will have a common interface. The Rabbit 4000 also has multiprocessor capabilities. The slave port permits configuration from an external device.

The chip will come in 16- by 16-mm LQFP and 10- by 10-mm TFBGA packages. It will be available in quantity next March.

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.
