I have run across some conflicting information and I need to track down the correct answer.

In the datasheet for the LPC4357FET256, page 57 lists the pin description for USB0_VBUS. It lists notes 6 and 7 for this pin. Note 6 on page 60 states: 5 V tolerant transparent analog pad.

However, in the LPC4357FET256 User’s Manual, in Chapter 25 (USB0) and on page 644 is states: This input is only 5 V tolerant when VDDIO is present.

Which is correct? I need to know if the dedicate pin on the device, USB0_VBUS is 5V tolerant when power (VDDIO) is NOT present.

Many thanks,

Brian
