CC-WST-DW7A-NM

Overview

The Digi CC-WST-DW7A-NM is a ConnectCore MP157 system-on-module based on the STM32MP157C microprocessor. It features a dual-core Arm Cortex-A7 running at 650 MHz and an Arm Cortex-M4 core at 209 MHz, integrated with a 3D GPU. The module includes 1 GB of DDR3L memory and 1 GB of SLC NAND flash. Connectivity options consist of pre-certified Wi-Fi 5 (802.11a/b/g/n/ac) and Bluetooth 5.2, alongside Gigabit Ethernet support. Designed for industrial environments, it operates within a temperature range of -40 °C to 85 °C.

Feature Summary

• STM32MP157C processor with dual Cortex-A7 cores at 650 MHz and Cortex-M4 at 209 MHz
• Integrated Vivante 3D GPU supporting OpenGL ES 2.0 at up to 533 MHz
• Pre-certified dual-band Wi-Fi 5 and Bluetooth 5.2 wireless connectivity
• Digi TrustFence security framework with secure boot and hardware encryption

Applications

• Industrial headless gateways requiring rich connectivity
• Display devices utilizing advanced HMIs and camera interfaces
• Medical embedded systems demanding high reliability and longevity

Procurement Notes

Verify component authenticity through authorized Digi International channels. Confirm that the specific ordering suffix matches the required memory configuration and regional radio certifications. Ensure compliance with RoHS standards and check for any updated certification documentation relevant to the target deployment region before procurement.

Selection Notes

Select this model when 1 GB of RAM and storage are necessary for complex Linux-based applications. The inclusion of a 3D GPU makes it suitable for graphical user interface implementations. Compare against the CC-WST-DW69-NM if lower memory capacity suffices, or consider the MP133 variant for single-core Cortex-A7 requirements.

Part Context

This module belongs to the Digi ConnectCore MP1 family, designed as a scalable platform for IoT applications. It maintains pin-compatibility with previous ConnectCore 6UL modules to facilitate design transitions. The product supports Digi Embedded Yocto Linux and offers long-term supply availability for industrial deployments.

Replacement Considerations

The CC-WST-DW69-NM serves as a direct alternative within the same form factor but provides reduced memory specifications (512 MB DDR3L and 512 MB SLC NAND). Evaluate software compatibility and memory constraints before substituting.
