Hello,

I'm doing some analysis on LuckFox Pico-Pro Max board and found something I don't understand.
From the schematic it can be seen that VCC_VDDR is taken directly from 1.8V, however the datasheet for the RV1106G specifies that the maximum DDR_IO voltage is 1.45V, and reccomended is 1.35V.

I have measured the voltage on the pin and I get 1.8V, so the schematic is correct.
The board works, but I am wondering if this is a HW error or if the datasheet is not correct.

Thanks

Hello, VCC_DDR The current batch of power supply has been adjusted (the schematic diagram has not been updated), and the 1.8V power supply of the old scheme has also passed the hardware review and stress test of Rockchip, and the actual design is subject to the latest official datasheet
