Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted or non-existent through standard distribution channels. Verification of current stock status and potential obsolescence notices is required before integration into new designs. Alternative sourcing may involve secondary market distributors, though authenticity and condition cannot be guaranteed. Designers should initiate replacement strategies immediately.

Selection Notes

Selection of this module requires consideration of its legacy ARM7TDMI architecture and limited processing speed compared to modern alternatives. The fixed memory configuration and specific interface requirements must align with project constraints. Due to its discontinued status, long-term supply chain stability is not assured. Engineers evaluating this part should assess compatibility with existing firmware ecosystems and verify that the thermal and electrical specifications meet the target application environment without requiring significant redesign.

Part Context

The DC-ME4-01T-S-50 belongs to the Digi Connect ME family of wireless and wired modules. This series was designed for embedded applications requiring reliable network connectivity. The specific model variant indicates a particular memory and feature set within the broader product line. Understanding the context of the Connect ME platform helps in identifying compatible development tools and software libraries historically supported by Digi International for similar architectures.
