Time [us]

Notes:

1.VOS_MAX is the measured overshoot voltage.

2.TOS_MAX is the measured time duration above VccMAX(I1).

3.Istep: Load Release Current Step, for example, I2 to I1, where I2 > I1.

4.VccMAX(I1) = VID - I1*RLL + 15 mV

7.8.3Signal DC Specifications

DC specifications are defined at the processor pads, unless otherwise noted. DC specifications are only valid while meeting specifications for case temperature (TCASE specified in Section 5, “Thermal Management Specifications”), clock frequency, and input voltages. Care should be taken to read all notes associated with each specification.
