General Hardware Architecture


*Not all shown features available on every model.
Please see the hardware comparison guide or specific product pinouts for exact model information.*

Field Readiness

Deployable with production grade code using supported development environments.

Electromagnetic Compatibility

EMC has been completed for certain automotive applications, but is specific to each use case. Reach out for more details if EMC is required for your application.

  • Radiated and conducted emissions
  • Immunity to conducted transients on power leads
  • Immunity to electrostatic discharge
  • Immunity to electromagnetic fields
  • Immunity to radiated electromagnetic fields

MATLAB Add-on Requirements

To program in MATLAB using the complimentary toolbox you will require the following add-ons from MATLAB:

  • MATLAB
  • Simulink
  • MATLAB Coder
  • Simulink Coder
  • Embedded Coder
  • (Optional) Stateflow
  • (Optional) IEC Certification Kit for ISO 26262

Need more than what is on board? Our products are easily expandable with our CANbus and Ethernet modules. There is a wide range of available add-ons. Contact us to add any of the following:
