We are looking for information on how to implement a USB-bus powered system with 'C5535. We are especially interested in a cost-optimized solution that implements the power supply sequencing described in 5.7.2.4 of the datasheet (1. USB_VDDA1P3 and USB_VDD1P3, 2. USB_VDDA3P3, 3. USB_VBUS).
The 5535EZDSP schematic is a good reference however it includes a lot of extra circuitry for FTDI based USB debug, and it also doesn't see to implement the required sequencing.
Thanks,
Ruben
