A.1.6 ESD Protection and Latch-up Immunity

All ESD testing is in conformity with CDF-AEC-Q100 Stress test qualification for Automotive Grade

Integrated Circuits. During the device qualification ESD stresses were performed for the Human Body

Model (HBM), the Machine Model (MM) and the Charge Device Model.

A device will be defined as a failure if after exposure to ESD pulses the device no longer meets the device

specification. Complete DC parametric and functional testing is performed per the applicable device

specification at room temperature followed by hot temperature, unless specified otherwise in the device

specification.

5. Those pins are internally clamped to VSSPLL and VDDPLL.

6. This pin is clamped low to VSSPLL, but not clamped high. This pin must be tied low in applications.
