RabbitCore® RCM3100 Series

The RabbitCore RCM3100 series microprocessor core module is the ideal option for engineers who want to rapidly develop and implement embedded systems. Powered by the new Rabbit® 3000 microprocessor, the compact RCM3100 boasts powerful features and a small footprint–1.85" × 1.65" (47 × 42 mm)–to simplify integration.

The RCM3100 series has 6 serial ports and operates at 29.4 MHz and 3.3V (with 5V-tolerant I/O). Built-in low-EMI features, including a clock spectrum spreader, help designers eliminate the kind of emissions-related problems that frequently derail tight development schedules.

Available in two models, the RCM3100 is equipped with up to 512K each of Flash and SRAM, quadrature encoder inputs, PWM outputs, and pulse capture and measurement capabilities. Two 34-pin connection headers provide 54 digital I/O shared with the 6 serial ports and alternate I/O features. (The RCM3100 series is pin compatible with the Ethernet RCM3000, facilitating cost-effective implementation of both Ethernet and non-Ethernet systems.)

The RCM3100 series features a battery-backable real-time clock, glueless memory and I/O interfacing, and low power "sleepy" modes (<2mA). A fully enabled 8-bit slave port permits easy master-slave interfacing with another processor-based system, and an alternate I/O bus can be configured for 8 data lines and 6 address lines (shared with parallel I/O). The Rabbit 3000 processor's compact, C-friendly instruction set and high clock speeds produce exceptionally fast results for math, logic, and I/O.

Designing with RabbitCores

The RabbitCore family of microprocessor core modules is designed to facilitate rapid development and implementation of embedded systems. RabbitCores are powered by high-performance 8-bit Rabbit microprocessors with extensive integrated features and a C-friendly instruction set designed for use with the Dynamic C® development system. The RabbitCore mounts on a user-designed motherboard and acts as the controlling microprocessor for the user's system. Small in size but packed with powerful features, these core modules give designers a complete package for control and communication.
