CYUSB3014-BZXI USB 3.0 Device

Hi,

I am using Cypress'  CYUSB3014 USB 3.0 device controller in my design. I found that the pins L5 & J11 of the device are connected to SRAM_VDD (power rail) in a development kit which used the sama part. My confusion is that whether L5 & J11 are to supply power to the 512 KB embedded SRAM or is it related to 'Boot from GPIF II ASync SRAM mode' as in device's datasheet ? I have attached the development kit (PDF) with this mail. Waiting for your reply.

Regards,

Madhu

Where has it been mentioned that L5 and J11 are powering SRAM?

I'm not able to correlate how you came to this conclusion. Please point to the document you're referring.

Regards,

Anand
