The STM32F401VCT7 100-LQFP package brings out 81 I/O lines, enough to handle a TFT display parallel bus alongside USB OTG and several UARTs without pin-mux gymnastics.
The base product number STM32F401 covers a range of Flash and RAM options in the same footprint, so if a future spin needs more memory the migration path stays within the same 100-LQFP board layout.
The suffix 'T7' versus 'T6' indicates the operating temperature grade. Both share the same 84 MHz Cortex-M4 core, 256 KB Flash, 64 KB RAM, and 100-LQFP package — the only difference is the high-temperature ceiling.
