NOTE: 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.

Texas Instrument DSPs do not require specific power sequencing between the core supply and the I/O supply. However, systems should be
designed to ensure that neither supply is powered up for extended periods of time if the other supply is below the proper operating voltage.
Excessive exposure to these conditions can adversely affect the long-term reliability of the devices. System-level concerns such as bus
contention may require supply sequencing to be implemented. In this case, the core supply should be powered up at the same time as or prior
to the I/O buffers, and then powered down after the I/O buffers.
