Electrical characteristics
— Configurable No Slew-Rate, Slow Slew-Rate, and Fast Slew-Rate on Slow, Medium, and SLR
driver pads
— VDD_HV_PDI NOTE: All pads are NOT 5 V TOLERANT. Pads are not capable of driving to
or from voltages above their respective VDD_HV_PDI. In other words, you cannot connect a
3.3V external device to a pad supplied with 2.5 V. If a pad must be connected to a 3.3V device,
its local VDD_HV_PDI must be 3.3 V. Injection current is then handled by the intrinsic diodes
from the pad transistors and by the ESD diodes.
— VDD_HV_PDI range
– 1.8 V nominal
– 2.5 V nominal
– 3.3 V nominal
• Receiver
— Selectable hysteresis Input Buffer.
