Design Considerations

This section presents design considerations for developers who are interested in alternative platforms to the Intel® Joule™ module. You may be a developer interested in transitioning from the Intel® Joule™ platform to the latest embedded processor products from Intel to take advantage of new features. Or you may have been considering developing with the Intel® Joule™ module but now that it has been discontinued, must choose another platform to develop on. We outline below important design considerations for both kinds of developers. Here we focus on comparing the Intel® Joule™ platform to the Atom® processor E3900 series.

  • Form factor
    The Intel Atom® processor E3900 series (formerly codenamed Apollo Lake) board area will probably increase because of a larger SoC package size, larger Power Management IC (PMIC) and Voltage Regulator (VR) solution space, and memory down (i.e. not package-on-package).
  • Performance Differences
    Lower operating frequencies on latest generation of Intel Atom® processor E3900 series, smaller cache size per core pair (e.g. 2MB vs 1MB) may affect performance. Memory configuration differences may have an impact since Intel Atom® processor E3900 series have higher peak BW, but lower transfer rate.
  • I/O Interface Limitations
    Intel Atom® processor E3900 series supports a single LPSS SPI port, compared to Joule’s two LPSS SPI ports; The Intel® Joule™ module supports USB 2.0 and USB 3.0 OTG while the Intel Atom® processor E3900 series supports USB 2.0 and USB 3.0 dual-role (it does not support OTG).
  • Completing design regulatory testing
    A design with the Intel Atom® processor E3900 series will need to go through various types of emissions certifications, safety certifications, and environmental certifications.
  • Driver Compatibility
    Register compatibility and I/O location compatibility from an Intel® Joule™ module to an Intel Atom® processor E3900 series may require driver changes.
  • Additional Features of the Intel Atom® processor E3900 series
    The Intel Atom® processor E3900 series has some new features and interfaces over Intel® Joule™ modules. Taking advantage of these interfaces and features may extend design and validation time of a migration, when compared to a situation where no new features are added.
  • Wireless Technology
    There is no integrated Wi-Fi and Bluetooth® on the Intel Atom® processor E3900 series.
  • Power Management
    Intel® Joule™ module does not support traditional PC sleep states (S3 , S4, S5), while the Intel Atom® processor E3900 series does.

The Intel® Joule™ module, now discontinued, was a compact yet powerful modular device that included wireless and video capabilities. The feature comparison and design considerations sections of this paper served as general guidance for developers interested in alternatives to the Intel® Joule™ platform. And the last section presented the UP Squared* Grove* IoT Development Kit as a complete kit alternative to the Intel® Joule™ platform.

For developers not interested in the kit alternative and instead plan on selecting an individual processor product, please note that you may need to work with a hardware vendor to create a custom board. However, there are some alternate products (modular in nature) available through the Solutions Directory from Intel to consider:
