Rabbit 4000

Rabbit 4000 8-bit


The Rabbit 4000 is a high-performance microprocessor with low electromagnetic interference (EMI), and is designed specifically for embedded control, communications, and Ethernet connectivity. The 8-bit Rabbit 4000 outperforms most 16–bit processors without losing the efficiency of an 8–bit architecture.

Product Description

The Rabbit 4000 is fast, running at up to 60 MHz, with compact code and support for up to 16 MB of memory. Operating with a 1.8 V core and 3.3 or 1.8 V I/O, the Rabbit 4000 boasts an internal 10Base-T Ethernet interface, eight channels of DMA, six serial ports with IrDA, 40+ digital I/O, quadrature decoder, PWM outputs, and pulse capture and measurement capabilities. It also features a battery-backable real-time clock, glueless memory and I/O interfacing, and ultra-low power modes. Four levels of interrupt priority allow fast response to real-time events. Its compact instruction set and high clock speeds give the Rabbit 4000 exceptionally fast math, logic, and I/O performance.
