, maximum synchronous baud
rate of 5.52 Mbps. Two ports are config-
urable as clocked ports.
Appendix A, “RabbitCore RCM2100 Specifica-
tions,” provides detailed specifications for the Rab-
bitCore RCM2100 series.
Five versions of the RabbitCore RCM2100 series
are available. Their standard features are summa-
rized in Table 1.
1.2 Advantages of the Rabbit-
Core RCM2100 Series
• Fast time to market using a fully engi-
neered, “ready to run” microprocessor
core.
• Competitive pricing when compared with
the alternative of purchasing and assem-
bling individual components.
• Easy C-language program development
and debugging, including rapid produc-
tion loading of programs.
• Generous memory size allows large pro-
grams with tens of thousands of lines of
code, and substantial data storage.
• Integrated Ethernet port (on selected mod-
els) for network connectivity, royalty-free
TCP/IP software.
• Models with and without Ethernet for flex-
ible production options.
• Small size and identical footprint and
pinout for all models.
1.3 Development and Evalua-
tion Tools
A complete Development Kit, including a Prototyp-
ing Board, accessory components and Dynamic C
development software, is available to accompany
the RCM2100 module. The Development Kit puts
together the essentials you need to design an embed-
ded microprocessor-based system rapidly and effi-
ciently.
See the RabbitCore RCM2100 Series Getting
Started Manual for complete information on the
Development Kit.
