(1) 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.
(2) All voltage values are with respect to V_SS.

(1) 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 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 TI. Not incorporating a flexible supply may limit the system's ability to easily adapt to future versions
of C641x devices.
