Procurement Notes

This product is officially listed as obsolete by the manufacturer. Verification of current availability requires checking distributor inventory status directly. No new manufacturing units are produced. Engineers should review the Product Change Notice (PCN) dated October 30, 2024, regarding obsolescence details before initiating any procurement actions.

Selection Notes

Designers selecting this module must account for its obsolete status and limited future supply. The Rabbit 3000 architecture dictates specific software development environments, such as Dynamic C. Alternative modern microprocessors may offer higher performance but require significant architectural redesign. Verify that the 29.4 MHz speed and 256 KB memory limits meet the target application's computational requirements.

Part Context

The 20-101-1246 is part of the RabbitCore family of embedded modules from Digi International. This series provides pre-integrated microprocessor solutions designed to simplify hardware design for industrial applications. Similar models in the lineup include the 20-101-0562 and 20-101-1154, which feature different processor generations or memory configurations within the same connector standard.

Replacement Considerations

As the component is obsolete, direct replacements are not available from Digi. Evaluation of third-party embedded modules with compatible pinouts or migration to newer RabbitCore variants is necessary. Cross-referencing with other manufacturers' MPU cores requires adapter boards or custom PCB redesign.
