Variants in the STM32G474 sub-family primarily scale by memory density and package size. Flash capacity ranges from 128KB to 512KB, while package options extend from compact 48-pin LQFP and QFN footprints to 128-pin LQFP or BGA options. Higher pin-count versions like the STM32G474QET6 provide more GPIOs and access to the full array of analog peripherals, whereas the STM32G474CBT6 offers a smaller footprint for space-constrained designs with reduced I/O.
