Security-capable TI processors include a dedicated security subsystem that runs on cores isolated from the main application processors and enforces the hardware root of trust through TI-supplied firmware (TI Foundational Security - TIFS). On newer-generation devices, a second dedicated security core is available for customer HSM software stacks, enabling cryptographic services without exposing key material to application-domain software.

A public key permanently provisioned into the silicon at production time anchors secure boot. On security-enforced (HS-SE) device variants, the boot ROM verifies a digital signature on the primary firmware image before execution and rejects images that fail verification, providing hardware-enforced integrity and authenticity verification from power-on.

Hardware access control partitions on-chip memory into zones assigned to each processing domain, preventing unauthorized reads or writes across workload boundaries.

On security-capable device variants, the debug interface can be permanently disabled for production units, or restricted to access only after a request is authenticated through a signed certificate, closing common attack vectors that exploit debugging tools.

Each chip carries a unique die ID alongside the part number, enabling precise identification of the specific silicon instance and supporting product identification requirements.
