1–2 Introduction RabbitCore RCM2200
• 4 address lines (A0–A3)
• Memory I/0 read, write
• External reset input
• Five 8-bit timers (cascadable in pairs) and
two 10-bit timers
• 256K flash memory, 128K SRAM
• Real-time clock
• Watchdog supervisor
• Provision for customer-supplied backup
battery via connections on header J5
• 10Base-T RJ-45 Ethernet port
• Raw Ethernet and two associated LED
control signals available on 26-pin header
• Three CMOS-compatible serial ports: max-
imum asynchronous baud rate of
345,600 bps, maximum synchronous baud
rate of 138,240 bps. One port is config-
urable as a clocked port.
• Six additional I/O lines are located on the
programming port, can be used as I/O lines
when the programming port is not being
used for programming or in-circuit debug-
ging—one synchronous serial port can also
be used as two general CMOS inputs and
one general CMOS output, and there are
two additional inputs and one additional
output.
Appendix A, “RabbitCore RCM2200 Specifica-
tions,” provides detailed specifications for the Rab-
bitCore RCM2200.
1.2 Advantages of the
RabbitCore RCM2200
• 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 for network con-
nectivity, royalty-free TCP/IP software.
1.3 Development and
Evaluation Tools
A complete Development Kit, including a Prototyp-
ing Board, and Dynamic C development software, is
available to accompany the RCM2200 module. The
Development Kit puts together the essentials you
need to design an embedded microprocessor-based
system rapidly and efficiently.
See the RabbitCore RCM2200 Getting Started
Manual for complete information on the Develop-
ment Kit.
1.4 How to Use This Manual
This user’s manual is intended to give users detailed
information on the RCM2200 module. It does not
contain detailed information on the Dynamic C
development environment or the TCP/IP software
support for the integrated Ethernet port. Most users
will want more detailed information on some or all
of these topics in order to put the RCM2200 module
to effective use.
1.4.1 Additional Product Information
Introductory information about the RabbitCore
RCM2200 and its associated Development Kit and
Prototyping Board will be found in the printed Rab-
bitCore RCM2200 Getting Started Manual, which
is also provided on the accompanying CD-ROM in
both HTML and Adobe PDF format.
We recommend that any users unfamiliar with
Z-World products, or those who will be using the
prototyping board for initial evaluation and develop-
ment, begin with at least a read-through of the Get-
ting Started manual.
