1. INTRODUCTION & OVERVIEW
The RCM2200 is an advanced module that incorporates the pow-
erful Rabbit 2000
®
microprocessor, flash memory, SRAM, digital
I/O ports, and a 10/100-compatible Ethernet port with a 10Base-T
interface, all on a PCB just half the size of a business card.
Throughout this manual, the term RCM2200 refers to the complete series of RCM2200
RabbitCore modules unless other production models are referred to specifically.
1.1 RCM2200 Description
The RCM2200 is a small-footprint module designed for use on a motherboard that sup-
plies power and interface to real-world I/O devices. Its two 26-pin connection headers
provide 26 parallel user I/O lines, shared with three serial ports, along with data, address
and control lines. A fourth serial port and three additional I/O lines are available on the
programming 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 RCM2200 is equipped with a 10/100-compatible Ethernet port with a 10Base-T inter-
face, 256K flash memory and 128K static RAM.
There are four production models in the RCM2200 series. Their standard features are
summarized in Table 1.
