Can you offer power on sequence of CYUSB3304 Figure or datasheet for reference , Thank !!
There is no specific power-on sequence for the two supplies, 3.3V and 1.2V in HX3. However, the RESETN pin should be held low until both these supplies become stable.The minimum delay for RESETN pin is recommended as 5 ms.
