TX2 / TX2UL  as USB Host controller

Question: Can we use the TX2 /TX2UL as USB Host controller?

 

Answer:

No. The TX2 / TX2UL device (CY7C68000 / CY7C68003) cannot be used as USB Host controller since it does not have two important features which are required so that it can be used as a Host Controller.

 

 

The important features are:

 

 

 

1) Ability to determine the speed of the device connected. If a high speed device is connected, the host must be able to detect chirp sequence from the host end.

 

 

 

2) The host must have a circuitry to detect connect and disconnect event.
