2.3. Power domain separation and ESD protection

The epc660 chip has internally 10 different power domains and 6 ground references which are interconnected with ESD protection diodes.

All pins are also equipped with ESD protection diodes. The diodes have a breakthrough voltage of 0.3V. The designer has to take care that

none of these diodes become conductive either at power-up, power-down or normal operation.
