Enhanced Rabbit microprocessor

16 November 2005 DSP, Micros & Memory

The Rabbit 4000 is the newest addition to Rabbit Semiconductor's Rabbit line of low-EMI microprocessors. Like its predecessors, it is designed specifically for embedded control, communications, and Ethernet connectivity. However, Rabbit 4000 offers new and improved features, which 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. The Rabbit 4000 micro can be programmed with the Dynamic C software development system. Rabbit 4000 is offered in 128-pin TQFP and 128-pin TFBGA configurations.
