1. INTRODUCTION & OVERVIEW
The RCM2100 series is an advanced line of modules that incor-
porates the powerful Rabbit 2000 microprocessor, flash mem-
ory, static RAM and an RJ-45 Ethernet port, all on a PCB the
size of a business card.
The RCM2100 series modules are designed for use on a motherboard that supplies power
and interface to real-world I/O devices. Up to 40 pins of I/O and four serial ports are avail-
able for system interfacing.
To accommodate a variety of user and production needs, the RCM2100 family includes
versions with varying amounts of onboard memory. Models with and without the Ethernet
port are available, to permit simultaneous development of Ethernet-capable and cheaper
non-Ethernet versions of production systems. All modules within the family are pin-for-
pin compatible and may be installed or swapped in a matter of minutes.
1.1 RCM2100 Series Description
There are four production models in the RCM2100 module series, with an additional mod-
ule that can be ordered in production quantities. If the standard models do not serve a
user’s needs, other variations can be specified and ordered in production quantities. (Con-
tact your Z-World or Rabbit Semiconductor sales representative for details.)
Table 1 below provides a summary of all the models in the RCM2100 family.
