Datasheet Volume One
Notes:
1. V
OS_MAX
is the measured overshoot voltage.
2. T
OS_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
7.8.3 Signal DC Specifications
DC specifications are defined at the processor pads, unless otherwise noted.
DC specifications are only valid while meeting specifications for case temperature
(T
CASE
specified in Section 5, “Thermal Management Specifications”), clock frequency,
and input voltages. Care should be taken to read all notes associated with each
specification.
