Thank you.
1V8 is the "current" standard in interfacing chips (esp. on low power designed systems).
The RP2350 can support 1V8.
Sure, cable length: but I need for testing embedded systems, designed for 1V8 operation.
Not difficult to design a RP2350 board for 1V8: just VDDIO as 1V8, with one exception:
using also PSRAM with a second nCS2 signal (from GPIO bank with 1V8) requires to run also QSPI as 1V8.
The reason why I am asking:
Using a 3V3 designed board, and afterwards using level shifters to bring it to 1V8 external devices - creates delays, more costs, more complexity (PCB design).
I wish to have a Raspberry Pi Pico 2 board where I can jumper VDDIO.
And I use already an FPGA (just for the level shifting) - works.
