Hello
Ordering Information is on page17 of the HX3PD data sheet (Document Number: 002-16615 Rev. * F). There is a description of "Signed FW Download" in Table5 Ordering Information, but could you please tell me more details about the difference between (Signed FW Download="No" and Signed FW Download="Yes"?)/ Merit and Demerit.
Best Regards,
Arai

Hi,
Signed Firmware Update is the process of updating an embedded controller in the field with a ‘Digitally Signed’ firmware. Placing a digital signature in the firmware ensures authenticity of the firmware from the manufacturer. The hardware cannot be programmed with un-authentic or malicious firmware, thus providing a high level of security to the OEM’s and end customers.
HX3PD has the option of signed firmware update feature, which is supported on the part CYUSB4357-BZXC. The composite firmware image will be digitally signed by a private key that will be private to the customer/OEM. Every firmware update will involve verifying the signature from the manufacturer before the controller is programmed with the associated firmware. This ensures that firmware update will happen only with firmware from a trusted source which is approved by the manufacturer.

Rajath
