Rabbit 4000 Microprocessor The Rabbit 4000 is a
high-performance, low-EMI microprocessor designed specifically for embedded
control, communications, and Ethernet connectivity.
The Rabbit 4000
outperforms most 16–bit processors without losing the efficiency of an
8–bit architecture. Extensive integrated features, glueless architecture
and 10Base-T Ethernet facilitate rapid hardware design, while a new C-friendly
instruction set promotes efficient development of even the most complex
applications.
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.
