Rabbit Semiconductor / Digi RCM2020 RabbitCore

Description

RCM2000
The RCM2000 is a core module designed to be the heart of your own controller built
around the plug-in module. Data processing is done by a Rabbit 2000 microprocessor
operating at up to 25.8 MHz (RCM2000 and RCM2010).
The RCM2000 has a Rabbit 2000 microprocessor, a static RAM, a flash memory, 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 RCM2000 receives its +5 V power from the user board on which it is mounted. The
RCM2000 can interface will all kinds of digital devices through the user board.
The RCM2000 Development Kit comes with a Prototyping Board that can be used to
demonstrate the operation of the RCM2000 and to prototype new circuits.
