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.

Future variants of the C641xT DSPs may operate at voltages ranging from 1.0 V to 1.2 V to provide a range of system power/performance options.
TI highly recommends that users design-in a supply that can handle multiple voltages within this range (with 3% tolerances) by implementing
simple board changes such as reference resistor values or input pin configuration modifications. Examples of such supplies include the PT5406,
PT5815, PT6476, PT6505, and PT6719 series from Power Trends, a subsidiary of Texas Instruments. Not incorporating a flexible supply may
limit the system’s ability to easily adapt to future versions of C641xT devices.
§
The absolute maximum ratings should not be exceeded for more than 30% of the cycle period.
