Soc System On Chip Procurement Notes

Verify the specific suffix 'TGBALMR' against the manufacturer's official nomenclature table to confirm package type, temperature range, and safety/security feature availability. Ensure that any required functional safety certifications or security keys are explicitly included in the ordered part number variant.

Soc System On Chip Selection Notes

Select this model for applications requiring high-performance heterogeneous computing with integrated real-time control via the Cortex-R5F subsystems. Consider the DRA821U2 variant if fewer Ethernet ports are sufficient. Verify that the design accommodates the 17.2 mm x 17.2 mm FCBGA-433 package dimensions and IPC Class 3 PCB requirements.

Soc System On Chip Part Context

This component belongs to the Texas Instruments Jacinto 7 processor family, designed for automotive and industrial gateway applications. It shares the core architecture with other DRA821x variants but is distinguished by its specific peripheral configuration, including the full complement of four Ethernet ports found in the U4 series.
