TUSB320HI: Difference from TUSN320HAI

Part Number: TUSB320HI
Other Parts Discussed in Thread: TUSB320HAI,

Dear, Sir.

Initially, my customer was planning to apply TUSB320HAI, so they put an order to obtain it.

Unfortunately, wrong part TUSB320HI was delivered.

They are considering to reuse TUSB320HI instead of TUSB320HAI.

I tried to check both datasheet, etc.

1. Is there any remarkable difference between HI & HAI?

   (I found only "REVISION" difference)

2. IP Generation is differnt (HI = 2nd, HAI = 3rd).

   Is there any impact on the function & performance due to such difference?

Sorry to disturb your job regading this kind of matter, but hoping to get

your advice, at this time.

Best Regards,

H. Sakai

    Dear, Luis-san. 

    Thank you for your valuable information. 

    1. BTW, What is the meaning of "ECR"?

    2. I wonder actual max  I2C clock speed is 400kHz for both?

    Sorry to ask again regarding this kind of matter. 

    Best Regards, 

    H. Sakai

    Hello SAkai-san.

    ECR stands for ENABLE CONTROL REGISTER (there is a register that enables/disables the support for debug-accessories in UFP mode - This support is always enabled on the TUSB320HI ).

    Both devices support 400KHz I2C clock.

    Regards,
    DIego.
