Which mcu requires the lowest voltage to initialize? Can we do better than an STM32G07KBU6? What is this a function of? Is it: memory size, type of ARM core, number of connected pins ...

The minimum voltage of an STM32 depends on both the technology used and the respective test scope in production. For the latter reason, a minimum voltage of 2.0V is often guaranteed for so-called value line products.

However, you will find many STM32s that can be used from 1.65V: STM32F0, F3, L0, L1, while some members of one family so far is also guaranteed to work from 1.62V: STM32H7. Just open STM32CubeMX, activate the column Voltage Min in the MCU selector and you can choose your favourite.
