20-101-1154

Overview

The Digi 20-101-1154 is an embedded module based on the RabbitCore RCM4120 series, featuring a Rabbit 4000 core processor. It operates at a clock speed of 58.98MHz and includes 1MB of RAM and 512KB of flash memory. The module utilizes IDC connectors (2x25, 2x5) for interface connectivity. Its physical dimensions are 1.410 inches in length by 1.880 inches in width (36.00mm x 48.00mm). The component supports an operating temperature range from -40°C to 85°C and is classified as an MPU core module.

Feature Summary

• Rabbit 4000 core processor with 58.98MHz operating speed
• Integrated 1MB RAM and 512KB flash memory
• IDC connector interface type (2x25, 2x5)
• Industrial operating temperature range (-40°C ~ 85°C)

Applications

• Embedded computing systems requiring Rabbit 4000 architecture
• Industrial control applications within specified temperature ranges
• MPU core integration into custom carrier boards

Procurement Notes

Verify part status before procurement as the 20-101-1154 is listed as obsolete. Confirm availability through authorized distributors or secondary market channels. Check for Product Change Notices (PCN) regarding obsolescence dates, specifically noting updates from July 2022 and October 2024. Ensure compatibility with existing design infrastructure given the discontinued manufacturing status.

Selection Notes

Select this module when a Rabbit 4000 processor with 58.98MHz performance is required. Compare against the 20-101-0562 (Rabbit 3000, 29.4MHz) if lower processing power suffices. Verify that the 1MB RAM and 512KB Flash meet application memory requirements. Ensure the host board supports the specific 2x25 and 2x5 IDC connector layout.

Part Context

This part belongs to the RabbitCore RCM4120 series manufactured by Digi International. It is distinct from the RCM4010 evaluation board (101-1114) and the Rabbit 3000-based module (20-101-0562). The module serves as a standalone embedded computer solution rather than a development kit or peripheral sensor.

Replacement Considerations

No direct public substitute part numbers are confirmed. As the product is obsolete, alternative solutions require redesigning the hardware to accommodate different processor architectures or evaluating other RabbitCore modules with similar specifications if available.
