1. INTRODUCTION
The RCM3000 RabbitCore module is designed to be the heart of
embedded control systems. The RCM3000 features an inte-
grated Ethernet port and provides for LAN and Internet-enabled
systems to be built as easily as serial-communication systems.
The RCM3000 has a Rabbit 3000 microprocessor operating at 29.4 MHz, static RAM,
flash memory, two clocks (main oscillator and timekeeping), and the circuitry necessary
for reset and 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 RCM3000 receives its +3.3 V power from the customer-supplied motherboard on
which it is mounted. The RabbitCore RCM3000 can interface with all kinds of CMOS-
compatible digital devices through the motherboard.
