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.

A version (C6414/15/16GLZA-5E0 and GLZA-6E3 only)
Future variants of the C641x DSPs may operate at voltages ranging from 0.9 V to 1.4 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 (i.e., 1.2 V, 1.25 V, 1.3 V, 1.35 V, 1.4 V
with
±
3% tolerances) by implementing simple board changes such as reference resistor values or input pin configuration modifications. Examples
of such supplies include the PT4660, PT5500, PT5520, PT6440, and PT6930 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 C641x devices.
§
The absolute maximum ratings should
not
be exceeded for more than 30% of the cycle period.
