RabbitCore® RCM3209 Series

Microprocessor core module

Digi Device Cloud
  • Rabbit 3000 microprocessor at 44 MHz
  • Optional 10/100Base-T Ethernet
  • 512K Flash / 256K SRAM / 512K Program Execution SRAM
  • 52 digital I/O and 6 serial ports for multiple device connecvity options
  • Product datasheet
  • Secure, anywhere management using Device Manager

Based on the Rabbit® 3000, the RabbitCore RCM3209 series provides the capability to integrate real-time control and Ethernet connectivity into your design. Engineers are freed from the limitations of serial port communications, allowing worldwide connectivity using low-cost networking hardware. The RCM3209 series replaces the previous RCM3200 versions as it adds the full industrial temperature spec.

The RCM3209 series and Dynamic C® are designed in a complementary fashion for maximum performance and easeof- use. Rabbit’s industry-proven Dynamic C is a C language environment that includes an editor, compiler and in-circuit debugger; no in-circuit emulator is required. An extensive library of drivers, sample programs and royalty-free TCP/IP stack with source code is included.

Device Manager

Device Manager is a feature of all Digi cellular gateways, routers, devices and components. Device Manager provides a robust suite of network management tools including authentication, configuration management, account management, asynchronous updates and alerts, group and individual software updating, network data storage and gateway programming.

Device Manager empowers IT, network operations and customer support organizations to conquer the challenges of managing the vast array of cellular equipment in their device networks. Network managers can remotely configure, upgrade, monitor and troubleshoot remote devices, and create applications that improve productivity, speed and efficiency.

The RCM3200 RabbitCore module series is a compact, simple solution to implement embedded functionality with options for 10/100Base-T Ethernet connectivity and industrial temperature range.

RabbitCore modules mount directly onto a user-designed motherboard and act as the controlling microprocessor for the system. The Ethernet device used on the RCM3209 series is able to detect automatically whether a crossover cable or a straight-through cable is being used in a particular setup, and will configure the signals on the Ethernet jack interface accordingly.

Developing with RabbitCores

The RabbitCore family of microprocessor core modules is designed to facilitate rapid development and implementation of embedded systems.


  • Rabbit® 3000 microprocessor @ 44.2 MHz
  • Battery-backed real-time clock
  • Low power “sleepy” modes
  • Easily interfaces with another processor-based board for distributed embedded systems

Design Advantages

  • Known good hardware to reduce design effort
  • Mount directly on a user-designed motherboard
  • Dynamic C® development environment for real-time development
  • Debug software directly on the target hardware

Designing with RabbitCores

The RCM3200 series is powered by the Rabbit 3000 microprocessor with extensive integrated features and a C-friendly instruction set designed for use with the development system

Develop programs with our industry-proven Dynamic C® integrated development environment, which includes an editor, compiler, and in-circuit debugger. This environment reduces effort and speeds hardware and software integration. Rabbit provides an extensive library of drivers and sample programs, along with royalty-free TCP/IP stack with source.

Download the program from your PC via USB or serial port, and debug right on the target hardware – no in-circuit emulation is required.
