ESD Structures
ESD Structures
The ESD structure generally consists of diodes from the signal pins to the power and ground rail. These
diodes are reverse biased with respect to the rails and serve to clamp external voltages to no more than
0.7 V beyond the rails.
Testing
Testing was completed on the bench at room temperature (25°C) using production samples. A limited
number of samples were tested; therefore, the results do not represent the performance of every device.
6
The following test scenarios were conducted outside of the published
device specifications. Do not subject MCUs or their components to
unrecommended conditions. Adverse effects may not be immediately
apparent, but the damaging phenomena described in this document may
deteriorate the life and/or performance of the MCU and/or its components.
See the device data sheet or user guide for the approved specifications.
