CC-MX-ET7D-ZN

Overview

The Digi CC-MX-ET7D-ZN is a System-on-Module (SOM) based on the NXP i.MX 8M Mini processor, featuring four Cortex-A53 cores at 1.6 GHz and a Cortex-M4 core. It includes 1 GB LPDDR4 RAM and 8 GB eMMC storage. The module integrates 1 Gb Ethernet with AVB support, operating within an industrial temperature range of -40°C to +85°C. Physical dimensions are 40 mm x 45 mm x 3.5 mm in a Digi SMTplus form factor.

Feature Summary

• Quad-core Arm Cortex-A53 processor with integrated Cortex-M4 for low-power processing
• Built-in security via Digi TrustFence, hardware Secure Element, and TrustZone
• Industrial-grade reliability with a 10+ year product lifecycle and wide operating temperature range
• Supports Yocto Project Linux and Android software platforms

Applications

• Industrial IoT gateways
• Human-machine interfaces (HMI)
• Equipment monitoring systems
• Edge computing nodes

Procurement Notes

Verify component authenticity through authorized Digi International channels. Confirm RoHS compliance status and specific revision levels against the latest datasheet before integration. Ensure carrier board design adheres to the specified castellated via layout and pitch requirements.

Selection Notes

Select this model for applications requiring wired Ethernet connectivity rather than wireless options. Compare memory configurations with the CC-WMX-ET7D-NN variant if wireless capability is needed instead of the standard Ethernet interface provided here.

Part Context

This module belongs to the ConnectCore 8M Mini family, designed for longevity and scalability. It utilizes the Digi SMTplus form factor to simplify design integration and improve reliability compared to traditional BGA packages.

Replacement Considerations

The CC-MX-ET8D-ZN serves as a direct substitute with identical specifications except for increased RAM capacity (2 GB LPDDR4). Verify that the target application can accommodate the additional memory bandwidth or requires the lower-cost 1 GB configuration.
