Hi,

 

In the datasheet there is written:

"Systems using CY7C65621/31 may have the option of using a
fuse ROM which is preset at the factory to configure the hub"

See App Note: AN61904

"Systems using HX2LP have the option of using a fuse
ROM, which is preset at the factory to configure the hub".

 

 

Does this mean pre-programmed in default mode or can be customized for customer's needs?

If customized: how? cost? min. Qty?

Is it possible to write on the internal ROM at costumer side?
