Procurement Notes

This part number is designated as End-of-Life (EOL) by the manufacturer. Availability is restricted or non-existent through standard distribution channels. Verification of current stock status requires direct inquiry with authorized distributors or checking for surplus inventory providers. Designers should initiate replacement strategies immediately due to the discontinued lifecycle status.

Selection Notes

Select this module only if legacy compatibility with the Digi Connect ME architecture is required. Ensure the host design accommodates the specific 55 MHz ARM7TDMI performance profile. Verify that the 8 MB RAM and 4 MB Flash capacities meet application storage needs. Confirm that the RJ45 connector type aligns with the target PCB layout requirements.

Part Context

The DC-ME4-01T-JT belongs to the Digi Connect ME product line, which provides modular solutions for embedded networking applications. It utilizes the NS9210/NS7520 processor family, distinct from later ARM-based modules in the ConnectME Wireless series. The 'JT' suffix typically denotes specific packaging or configuration variants within the Connect ME portfolio, often associated with JTAG connectivity features.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult Digi International's official transition guides for modern alternatives such as the XBee series or newer ConnectME Wireless modules that support NET+OS or Linux environments.
