First time I have seen a DRC XOR mask in a blog post

@wren6991 'Those of you interfacing RP2350 to retro computer hardware will be pleased to hear that, after an extensive qualification campaign, RP2350 is now officially 5V tolerant!' ooh (Hey where's that big pile of withdrawn A2's ?)

@thejpster Yes it depends on the external ramp. Ideally, switch the external supply to the 5V circuit and sequence it to come up after IOVDD, or hold the external 5V circuitry in a state (e.g. reset) where its outputs are low or floating.

@thejpster You could also look at disabling the internal regulator and adding an external LDO from 5V to Pico 3V3. That should track the external 5V ramp quite closely. It's not "nothing when unpowered" but rather "no more than 3.3V + 10% when unpowered".

@tom_verbeure We've been collecting data from ATE since A2 production ramp-up, but nothing to announce

@mwick83 it's stacked die, wire bonded by bouncing off of the lead frame :)
