Building upon the highly successful Rabbit 3000, the Rabbit 4000 is offered in two RoHS compliant packages, 128-pin TQFP and 128-pin TFBGA configurations. The new features include:

  • 500 new instructions
  • Integrated 10Base-T Ethernet
  • DMA
  • Full 16-bit memory device support
  • Page-mode memory device support
  • Memory enhancements with physical address space of up to 16 MB
  • New hardware security features
  • Hardware breakpoints
  • Improved I/O
  • Variable-phase PWM

Programming the Rabbit 4000 microprocessor is simple with the industry-proven Dynamic C® software development system. In addition, Rabbit developers do not need costly in-circuit emulators — programming is accomplished simply by connecting an interface cable from a PC to a Rabbit-based target system. Software development and debugging can be performed over Ethernet/Internet using appropriate accessory hardware or RabbitSys. Integrated features of the Rabbit 4000 allow embedded engineers to develop smaller designs, enabling for diverse implementation.

The Rabbit 4000 will be available in quantity March 2006.
