The RCM3209 and RCM3229 RabbitCore
®
modules are designed
to be the heart of embedded control systems. The RCM3209 fea-
tures an integrated 10/100Base-T Ethernet port and provides for
LAN and Internet-enabled systems to be built as easily as serial-
communication systems.
In addition to the features already mentioned above, the RCM3209 and RCM3229 have
two clocks (main oscillator and real-time clock), reset circuitry, and the circuitry necessary
for management of battery backup of the Rabbit 3000’s internal real-time clock and the
static RAM. Two 34-pin headers bring out the Rabbit 3000 I/O bus lines, parallel ports,
and serial ports.
The RCM3209 or RCM3229 re3.3 V power from the customer-supplied mother-
board on which it is mounted. The RCM3209 and RCM3229 can interface with all kinds
of CMOS-compatible digital devices through the motherboard.
The Development Kit has what you need to design your own microprocessor-based
system: a complete Dynamic C software development system and a Prototyping Board
that allows you to evaluate the RCM3209 or RCM3229, and to prototype circuits that
interface to the RCM3209 or RCM3229 module.
