20-101-1094

Overview

The Digi 20-101-1094 is a RabbitCore RCM4000 module based on the Rabbit 4000 microcontroller. It operates at a clock speed of 58.98 MHz and includes 512 KB of internal flash memory alongside 512 KB of internal RAM. The module provides 32 MB of external flash storage. Designed for embedded applications, it supports battery backup switching functionality to maintain system integrity during power transitions.

Feature Summary

• Integrated Rabbit 4000 processor architecture
• Combined internal and external non-volatile memory
• Battery backup switching capability

Applications

• Industrial automation control systems
• Embedded network device development
• IoT gateway hardware platforms

Procurement Notes

Verify that the specific revision matches the required firmware compatibility. Confirm that the 512 KB internal RAM meets the application's real-time processing needs. Ensure the 32 MB external flash capacity is sufficient for the intended codebase and data logging requirements before finalizing procurement.

Selection Notes

Select this module when a dedicated Rabbit 4000 environment is required rather than standard ARM or AVR architectures. Consider the 58.98 MHz performance ceiling against higher-speed alternatives if latency is critical. Evaluate the 512 KB internal RAM limit for complex multitasking scenarios requiring larger buffers.

Part Context

This component belongs to the RabbitCore family of modules produced by Digi International. It serves as a complete computing solution integrating the microcontroller with necessary memory resources. The RCM4000 designation indicates its role as a ready-to-use module for rapid prototyping and production embedding.
