TUSB9261: Readonly-Option

Part Number: TUSB9261

Hello TI & other experts, 

We have started a new server series design and for that we need a secure connection the a SD hard disk. Secure in the sense that it should be read only accessible, and it is not allowed to be so via a software tick mark which is usual, but has to be via hardware. Currently we see TUSB9261 (or similar which you might be able to suggest) as a very good option for this, requiring a small firmware change that will only allow reading from the harddisk. And of course sending commands still to tell where to read from.

Is TUSB9261 the right solution for this? Can the firmware be modified by TI? Will you assist regarding this? This is not just a one-off product.

Are there other ICs that are better/equally well suited for this?

Best, Christian Ahler
