DC-EM-02T-S

Overview

The Digi DC-EM-02T-S is a wired embedded module from the Digi Connect EM family, designed for drop-in integration. It features a 32-bit ARM7TDMI processor running at 55 MHz, paired with 4 MB of NOR flash and 8 MB of SDRAM. The module provides a 10/100 Mbps Ethernet interface via an integrated MAC/PHY and RJ-45 connector. It includes two high-speed TTL serial ports (up to 230 Kbps) and nine shared GPIO pins. Designed for industrial environments, it operates between -40°C and +85°C.

Feature Summary

• ARM7TDMI processor operating at 55 MHz
• Integrated 10/100Base-T Ethernet MAC and PHY
• Two UART ports supporting up to 230 Kbps data rates
• 9 shared GPIO pins and SPI master mode support

Applications

• Industrial IoT device servers
• Serial-to-Ethernet gateways
• Embedded network connectivity modules

Procurement Notes

Verify the specific suffix 'S' against the manufacturer's documentation to confirm pin header population and antenna connector status, as these options affect physical dimensions and electrical interfaces. Ensure compatibility with the 12-pin main header form factor for your target PCB design.

Selection Notes

Select this model for applications requiring reliable wired Ethernet connectivity in harsh environments due to its extended temperature range (-40°C to +85°C). Compare with the Wi-EM variant if wireless 802.11b capability is required instead of or in addition to the wired connection.

Part Context

This component belongs to the Digi Connect EM family, which shares a common platform design with the Digi Connect Wi-EM series. This allows for interchangeable hardware integration between wired and wireless solutions using a single board layout, simplifying product development and long-term availability planning.

Replacement Considerations
