CC-ST-J17D-ZK

Overview

The Digi CC-ST-J17D-ZK is a secure, industrial-grade System-on-Module (SOM) based on the STMicroelectronics STM32MP255C microprocessor. It features an Arm 64-bit dual Cortex-A35 processor running at 1.2 GHz, alongside Cortex-M33 and Cortex-M0+ cores. The module integrates a Neural Processing Unit (NPU) for edge AI and an Image Signal Processor (ISP) for computer vision. It includes 1 GB of DDR4 memory and 8 GB of eMMC storage. Designed for demanding environments, it operates within an industrial temperature range of -40 °C to 85 °C and utilizes the compact Digi SMTplus form factor.

Feature Summary

• STM32MP255C processor with dual Cortex-A35 cores at 1.2 GHz
• Integrated NPU (1.2 TOPS) and ISP for edge AI and vision tasks
• Industrial operating temperature range (-40 °C to 85 °C)
• Compact 30 mm x 30 mm SMTplus surface mount footprint

Applications

• Industrial automation and Industry 4.0 devices
• Edge AI and computer vision applications
• Smart connected devices requiring high reliability
• Battery-powered portable equipment due to power efficiency

Procurement Notes

Verify that the specific part number CC-ST-J17D-ZK corresponds to the Ethernet-only variant of the ConnectCore MP255 SOM. Confirm that the required wireless connectivity options are not needed, as this model lacks pre-certified Wi-Fi and Bluetooth modules included in the CC-WST-J17D-NK counterpart. Ensure carrier board designs support the 333-pad LGA interface.

Selection Notes

Select the CC-ST-J17D-ZK when wired Ethernet connectivity is sufficient and wireless radio certification is unnecessary. This model provides the same processing power, NPU, and security features as the wireless version but excludes the integrated Wi-Fi 6 and Bluetooth 5.4 radios. It is suitable for fixed installations where external cellular or XBee integration handles wireless needs.

Part Context

This component belongs to the Digi ConnectCore MP255 family of secure system-on-modules. It shares the core STM32MP255C processor and hardware specifications with the wireless variant (CC-WST-J17D-NK). The primary distinction is the absence of onboard wireless radios, positioning it as a cost-effective solution for wired industrial IoT deployments.

Replacement Considerations

The CC-WST-J17D-NK serves as the functional equivalent with added wireless capabilities. If wireless connectivity is required, the wireless variant must be selected instead. No other direct substitutes are documented in the provided datasheet.
