1.2 RCM3000 RabbitCore Modules
Throughout this manual, the term RCM3000 refers to the complete series of RCM3000
RabbitCore modules unless other production models are referred to specifically.
The RCM3000 RabbitCore modules are designed for use on a customer-supplied mother-
board that supplies power and interfaces to real-world I/O devices. Their two 34-pin con-
nection headers provide 52 parallel user I/O lines, shared with five serial ports, along with
control lines. A sixth serial port and one additional I/O line are available on the program-
ming header.
A fully enabled slave port permits glueless master-slave interface with another Rabbit-
based system. The slave port may also be used with non-Rabbit systems, although addi-
tional logic may be required.
The RCM3000 is equipped with a 10/100-compatible Ethernet port with a 10Base-T inter-
face, 256K–512K flash memory and 128K–512K static RAM.
There are two production models in the RCM3000 series. If the standard models do not
serve your needs, other variations can be specified and ordered in production quantities.

Table 1 below highlights the differences between the two models in the RCM3000 family.
NOTE:
The RCM3010 is the RabbitCore module supplied with the Development Kit.
In addition, there is an RCM3100 series of RabbitCore modules that omits the RCM3000
series’ Ethernet connectivity, but offer a much smaller footprint, which is about one-half
that of the RCM3000 series.
The RabbitCore modules can be programed locally, remotely, or via a network using
appropriate interface hardware.
