Digi RCM4000 - Manual (Page 7)

User’s Manual 1
1. I
NTRODUCTION
The RCM4000 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 five 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 RCM4000 also fea-
tures an integrated 10Base-T Ethernet port.
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 RCM4000 and to prototype circuits that interface
to the RCM4000 module. You will also be able to write and test
software for the RCM4000 modules.
Throughout this manual, the term RCM4000 refers to the complete series of RCM4000
RabbitCore modules unless other production models are referred to specifically.
The RCM4000 has a Rabbit 4000 microprocessor operating at up to 58.98 MHz, static
RAM, flash memory, NAND 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 the 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 RCM4000 receives its +3.3 V power from the customer-supplied motherboard on
which it is mounted. The RCM4000 can interface with all kinds of CMOS-compatible
digital devices through the motherboard.
