NTRODUCTION

The RCM4200 series of RabbitCore modules is one of the next

generation of core modules that take advantage of new Rabbit

®

4000 features such 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 embedded applications. The RCM4200 also features an
integrated 10/100Base-T Ethernet port, an A/D converter, and a
serial flash memory for mass storage.

Each production model has a Development Kit with the essentials
that you need to design your own microprocessor-based system,
and includes a complete Dynamic C software development sys-
tem. The Development Kits also contains a Prototyping Board
that will allow you to evaluate the specific RCM4200 module and
to prototype circuits that interface to the module. You will also
be able to write and test software for the RCM4200 modules.

Throughout this manual, the term RCM4200 refers to the complete series of RCM4200
RabbitCore modules unless other production models are referred to specifically.

The RCM4200 has a Rabbit 4000 microprocessor operating at up to 58.98 MHz, static
RAM, flash memory, serial flash mass-storage option, an 8-channel A/D converter, two
clocks (main oscillator and timekeeping), and the circuitry necessary for reset and man-
agement of battery backup of the Rabbit 4000’s internal real-time clock and 512K of static
RAM. One 50-pin header brings out the Rabbit 4000 I/O bus lines, parallel ports, A/D
converter channels, and serial ports.

The RCM4200 receives its +3.3 V power from the customer-supplied motherboard on
which it is mounted. The RCM4200 can interface with all kinds of CMOS-compatible
digital devices through the motherboard.
