I don't know whether this is true, but it's definitely possible (there are pin-compatible 64 KiB variants of the MCU). If you use the device without verifying the hardware, it's game over. To prevent Evil Maid attacks, that means checking at EVERY use.https://www.reddit.com/r/ledgerwallet/comments/86b7dk/important_to_everyone_who_bought_a_nano_ledger_s/ …

I don't actually see any 64KiB pin-compatible variants. The only STM32 part with 64K flash and USB in that package is the STM32F302K6 (or K8), which is a completely different series and CPU (F3/Cortex-M4 instead of C0/Cortex-M0) and has a slightly different pinout.

I thought I had seen one, but you have a lot more experience in this field so I'm willing to delegate to you on this :)

You never know with manufacturers; I just went through the ST parts picker and couldn't find anything that fit the bill, but if you think you've seen something it's worth taking a look again just in case.
