Procurement Notes

Verify the specific suffix 'C' indicates the industrial temperature grade (-40°C to +105°C) and 'A' denotes automotive qualification tier when sourcing. Confirm that the package type matches the 289-pin MAPBGA specification. Ensure compatibility with the i.MX RT1170AEC data sheet for automotive products. Check for any recent product change notifications affecting pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component for applications requiring deterministic real-time performance alongside rich multimedia processing. The dual-core design allows separation of safety-critical tasks on the M4 core from user interface logic on the M7 core. Consider the integrated power management unit if minimizing external components is a priority. Evaluate the available security features against regulatory requirements for automotive or industrial deployments.
