Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values are with respect to VSS.
For USB High-Speed, Full-Speed, and Low -Speed modes, USB I/Os adhere to Universal Serial Bus, revision 2.0 standard. For USB Super-Speed mode, USB I/Os adhere to Universal Serial Bus, revision 3.1 specification, revision 1.0 standard.
Overshoot/Undershoot percentage relative to I/O operating values - for example the maximum overshoot value for 1.8 V LVCMOS signals is DVDD18 + 0.20 × DVDD18 and maximum undershoot value would be VSS - 0.20 × DVDD18

Users are required to program their board CVDD supply initial value to 1.0 V on the device. The initial CVDD voltage at power-on will be 1.0 V nominal and it must transition to VID set value, immediately after being presented on the VCNTL pins. This is required to maintain full power functionality and reliability targets ensured by TI.
SRVnom refers to the unique SmartReflex core supply voltage that has a potential range of 0.8 V and 1.1 V which preset from the factory for each individual device. Your device may never be programmed to operate at the upper range but has been designed accordingly should it be determined to be acceptable or necessary. Power supplies intended to support the variable SRV function shall be capable of providing a 0.8 V-1.1 V dynamic range using a 4- or 6-bit binary input value which as provided by the DSP SmartReflex output.

For test conditions shown as MIN, MAX, or TYP, use the appropriate value specified in the recommended operating conditions table.
For USB High-Speed, Full-Speed, and Low-Speed modes, USB I/Os adhere to Universal Serial Bus, revision 2.0 standard. For USB Super-Speed mode, USB I/Os adhere to Universal Serial Bus, revision 3.1 specification, revision 1.0 standard.
I2C uses open collector I/Os and does not have a VOH minimum.
II applies to input-only pins and bidirectional pins. For input-only pins, II indicates the input leakage current. For bidirectional pins, II includes input leakage current and off-state (Hi-Z) output leakage current.
I2C uses open collector I/Os and does not have a IOH maximum.
IOZ applies to output-only pins, indicating off-state (Hi-Z) output leakage current.
