Procurement Notes

This component is officially classified as obsolete by the manufacturer and is no longer in active production. Sourcing should focus on verified surplus or secondary market channels. Buyers must confirm the authenticity of units through official distributor verification processes. Ensure that any available stock matches the specific RabbitCore RCM3220 specification to avoid compatibility issues with existing designs.

Selection Notes

Engineers requiring this specific module must account for its obsolete status when planning long-term product lifecycles. The Rabbit 3000 architecture offers deterministic performance suitable for real-time control but lacks modern high-speed interfaces found in newer processors. Selection should be driven by legacy system maintenance requirements rather than new design implementations, considering the limited availability of replacement components.

Part Context

The 20-101-0522 belongs to the RabbitCore family of embedded modules produced by Digi International. These modules were designed to simplify the integration of Rabbit Semiconductor processors into custom hardware. The RCM3220 variant specifically targets applications needing robust I/O handling and moderate processing power within a standardized form factor, bridging the gap between discrete MCU solutions and full computer boards.

Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete model. Designers typically migrate to newer Digi ConnectME or Xbee-based modules for wireless connectivity needs, or transition to ARM Cortex-M based SoMs for general processing. Specific pin-compatible replacements are not documented in public sources.
