Introduction 1
The RabbitCore RCM2200 microprocessor module is designed to be the heart
of embedded control systems. The RCM2200 features an integrated Ethernet
port and provides for LAN and Internet-enabled systems to be built as easily
as serial-communication systems.
The RabbitCore RCM2200 has a Rabbit 2000
microprocessor operating at 22.1 MHz, static RAM,
flash memory, two clocks (main oscillator and time-
keeping), and the circuitry necessary for reset and
management of battery backup of the Rabbit 2000’s
internal real-time clock and the static RAM. Two
26-pin headers bring out the Rabbit 2000 I/O bus
lines, address lines, data lines, parallel ports, and
serial ports.
The RabbitCore RCM2200 receives its +5 V power
from the user board on which it is mounted. The
RabbitCore RCM2200 can interface with all kinds
of CMOS-compatible digital devices through the
user board.
