2 RabbitCore RCM2100
1.1.1 Standard Ethernet Versions
There are two RCM2100 series modules that incorporate an Ethernet port:
RCM2100.
The RCM2100 is the most fully-equipped module in the family, with the Ethernet port, 512k
flash memory and 512k static RAM. The Ethernet port uses portions of two of the Rabbit 2000
microprocessor’s parallel ports, reducing the available number of I/O pins to 34. This is the version
included in the Development Kit.
RCM2110.
The RCM2110 is identical to the RCM2100 except that it is equipped with 128k of SRAM
and 256k of flash memory.
1.1.2 Standard Non-Ethernet Versions
To accommodate developers and users who want the RCM2100’s footprint and capabili-
ties other than the integrated Ethernet port, two standard versions of the module areavail-
able without the Ethernet hardware:
RCM2120.
The RCM2120 is equipped with 512k flash memory and 512k static RAM, but does not
include the Ethernet port hardware. In its place, ports D and E of the Rabbit 2000 microprocessor
are enabled, giving this module 40 I/O pins.
RCM2130.
The RCM2130 is identical to the RCM2120 except that it is equipped with 128k of SRAM
and 256k of flash memory.
1.1.3 Other Factory Versions
To further accommodate developers with specific needs, an additional version of the
RCM2100 module is available on special order:
RCM2115.
The RCM2115 is equipped with 256k flash memory and 128k static RAM as well as the Eth-
ernet port. This version does not include the RJ-45 jack and associated interface transformers. The
Ethernet signals are brought to a header for use by the production system. (Users will have to pro-
vide the interface components within their design.)
In addition to these standard models, production quantities of modules with custom con-
figurations of memory, I/O and Ethernet capability can be ordered.
