DC-ME4-01T-S-UPW

Overview

The Digi DC-ME4-01T-S-UPW is a System-On-Module based on the NS7520 ARM7TDMI processor running at 55MHz. It integrates 8MB of SDRAM and 4MB of Flash memory, providing essential embedded computing resources within a compact form factor measuring 36.7mm x 19.10mm. The module supports IEEE 802.3 Ethernet standards via an RJ45 connector with 10/100 Mbps speed capabilities. Designed for industrial environments, it operates reliably across a temperature range of -40°C to 85°C. This component includes standard firmware with a unique password (SB-327) for secure initial access.

Feature Summary

• Integrates ARM7TDMI processor with dedicated memory resources
• Supports standard Ethernet connectivity through RJ45 interface
• Engineered for wide industrial temperature operation ranges

Applications

• Industrial automation control systems
• Embedded network server implementations
• Remote monitoring and data acquisition devices

Procurement Notes

Verify current availability status as this component is scheduled for obsolescence by the manufacturer. Confirm that the specific SB-327 password variant matches project security requirements. Ensure mechanical fitment aligns with the 36.7mm x 19.10mm dimension constraints. Check for end-of-life transition plans from Digi International before finalizing procurement strategies.

Selection Notes

Select this module when a compact, low-power ARM7-based solution with integrated Ethernet is required. Consider the limited flash capacity for applications with minimal firmware storage needs. Evaluate the operating temperature range against environmental conditions. Verify compatibility with existing serial or parallel interfaces if expansion is necessary beyond the base Ethernet connection.

Part Context

This module belongs to the Digi Connect ME series, designed for embedded networking applications. It represents an earlier generation of system-on-module technology utilizing the NS7520 processor. The series focuses on providing reliable connectivity in constrained spaces. Understanding its position within the product lifecycle is crucial for long-term maintenance planning.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is scheduled for obsolescence, consult Digi International directly for recommended migration paths or newer equivalents within the Connect ME family.
