Highly Integrated Full Featured Hi-Speed USB 2.0 ULPI Transceiver
Datasheet
Chapter 4 Electrical Characteristics
The following conditions are assumed unless otherwise specified:
VVBAT = 3.1 to 5.5V; VDD18 = 1.6 to 2.0V; VDDIO = 1.6 to 2.0V; VSS = 0V; TA = -40°C to +85°C
The current for 3.3V circuits is sourced at the VBAT pin, except when using an external 3.3V supply
as shown in Figure 5.7.
