Hi Team

If want to calculate total current requirement by TUSB7320.

should I only need yo refer below spec?

if so. what is VDDA power requirement also same with 594mW?

Hi Brian C;

594 mA is current value for 1.1v . total current value for 3.3v is 115mA, including VDDA _3P3and VDD33.

Hi Brian Z

really appreciate your feedback.

two thing want to check with you

1. why total current for 3.3v is 115mA? it seems like for I/O port power supply and what is the definition for total power of right side.

their power team need to know total power for TUSB7320. could you recommend how many power do TUSB7320 need?

2. do TUSB7320 need any FW support?

total power is 623mw of 1.1v supply + 379mw of 3.3v supply = 1003mW.

ALL PC system should have default XHCI USB host FW, so there is no need for additional FW for TUSB7320.
