TUSB2E221: I2C idle in L1 and L2

Koyo Asaishi

Part Number: TUSB2E221

Hello team,

I2C and GPIO will be idle when TUSB2E221 is in L1 sleep or L2 suspend. Does idle mean I2C bus is unable to use until resume/remote wake event happened at DP/DN?

Best regards

Hi Koyo,

The TUSB2E221 should still be able to still perform I2C writes while the USB2 link is in a low power state. The state of the USB2 line should not affect TUSB2E221 functionality.

Thanks,

Ryan
