Rabbit Semiconductor Announces the New Rabbit 4000 Microprocessor

Rabbit Semiconductor announced the Rabbit 4000 as the newest addition to the Rabbit line of low-EMI microprocessors. The Rabbit 4000 like its predecessors is designed specifically for embedded control, communications, and Ethernet connectivity.

Building upon the Rabbit 3000, the Rabbit 4000 is offered in two RoHS compliant packages, 128-pin TQFP and 128-pin TFBGA configurations. The new features include integrated 10Base-T Ethernet, DMA, 16-bit memory device support, page-mode memory device support, and memory enhancements with physical address space of up to 16 MB. It also features hardware security features, hardware breakpoints, improved I/O, and variable-phase PWM. 500 new instructions have been added to increase the processing speed and efficiency.

Programming the Rabbit 4000 microprocessor is simple with the Dynamic C software development system. It is accomplished 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.

The Rabbit 4000 will be available in quantity March 2006.
