Procurement Notes

This component is officially listed as obsolete and no longer manufactured. Verification of availability requires checking current distributor stock levels or approved replacement part numbers. Designers should confirm end-of-life status and transition plans before finalizing procurement strategies.

Selection Notes

Select this module when a Rabbit 2000 core with high memory capacity (512K/512K) and native Ethernet is required. It is pin-compatible with other RCM2200 series variants like the RCM2250, allowing for memory upgrades without board redesign. Ensure the application supports the 5V logic level and IDC header interface.

Part Context

The 20-101-0955 corresponds to the RCM2260 model within the RabbitCore family. This series provides microprocessor core modules designed for rapid development of embedded systems. The RCM2260 represents the high-memory variant of the RCM2200 platform, offering expanded storage compared to the base RCM2200 or RCM2210 models.

Replacement Considerations

Digi recommends part number 20-101-0494 as the manufacturer-recommended substitute. This alternative maintains compatibility within the RabbitCore ecosystem.
