User’s Manual

1. INTRODUCTION

The RabbitCore RCM2000 series is a family of microprocessor

modules designed to be the heart of embedded control systems,

providing an array of I/O and addressing.

Throughout this manual, the term RCM2000 refers to the complete series of RCM2000

RabbitCore modules unless other production models are referred to specifically.

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.
