The Rabbit 4000 is fast, running at up to 60 MHz, with compact code and direct software support for 16-bit memory devices. Rabbit 4000 operates at 3.3 V I/O standard or can be set to 1.8 V for lower power. The Rabbit 4000 boasts 6 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. 3 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.
