Chapter 1. Introduction - Rabbit RabbitCore RCM4100 User Manual

The RCM4100 series is the first of the next-generation core
modules that take advantage of new Rabbit
as hardware DMA, clock speeds of up to 60 MHz, I/O lines
shared with up to six serial ports and four levels of alternate pin
functions that include variable-phase PWM, auxiliary I/O,
quadrature decoder, and input capture. Coupled with more than
500 new opcode instructions that help to reduce code size and
improve processing speed, this equates to a core module that is
fast, efficient, and the ideal solution for a wide range of embed-
ded applications.
The Development Kit has the essentials that you need to design
your own microprocessor-based system, and includes a com-
plete Dynamic C software development system. This Develop-
ment Kit also contains a Prototyping Board that will allow you
to evaluate the RCM4100 series and to prototype circuits that
interface to the RCM4100 series of modules. You will also be
able to write and test software for these modules.
Throughout this manual, the term RCM4100 series refers to the complete series of
RCM4100 RabbitCore modules unless other production models are referred to specifically.
The RCM4100 has a Rabbit 4000 microprocessor operating at up to 58.98 MHz, static
RAM, flash memory, an 8-channel A/D converter, two clocks (main oscillator and time-
keeping), and the circuitry necessary for reset and management of battery backup of the
Rabbit 4000's internal real-time clock and the static RAM. One 50-pin header brings out
the Rabbit 4000 I/O bus lines, parallel ports, and serial ports.
The RCM4100 series receives its +3.3 V power from the customer-supplied motherboard
on which it is mounted. The RCM4100 series can interface with all kinds of CMOS-
compatible digital devices through the motherboard.
