TUSB522P: Continuous polling

FuLien Chua

Part Number: TUSB522P
Other Parts Discussed in Thread: SN65LVPE512, TUSB422,

I face the same issue of continuous polling using tusb522. From the previous thread, this issue will be resolved by new releases of tusb522.

May I know the schedule and how to differentiate between old and new chip.

Hi Brian,

Apologise for my unclear question.

I meant to buy the new TUSB522P(engineering samples) to replace the current TUSB522P on my board. This is to check if the new TUSB522P resolves my issue.

I'm from Singapore.

Best regards,

Fu Lien
