Introduction 1
The RabbitCore RCM2100 series is a family of microprocessor modules
designed to be the heart of embedded control systems. In addition to the array
of I/O and addressing available on other Z-World products, the RCM2100
series offers an optional integrated Ethernet port. These modules permit LAN
and Internet-enabled systems to be built as easily as serial communications-
only systems.
Data processing is done by a Rabbit 2000 micropro-
cessor operating at 22 MHz.
The RabbitCore RCM2100 series has a Rabbit 2000
microprocessor, a static RAM, up to two flash mem-
ory chips, two quartz crystals (main oscillator and
timekeeping), 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 40-pin headers bring out the Rabbit 2000 I/O
bus, address lines, data lines, parallel ports, and
serial ports.
The RabbitCore RCM2100 series receives its +5 V
power from the user board on which it is mounted.
The RabbitCore RCM2100 series can interface with
all kinds of CMOS-compatible digital devices
through the user board.
