The 100-LQFP package brings out 86 I/O, so you can keep encoder inputs, current-sense ADC channels, and a display interface on the same chip.
Internal oscillator is on-chip, so you can bring up the core without an external crystal for basic operation; the PLL multiplies up to 72 MHz. Flash wait states need adjusting when crossing 48 MHz — standard Cortex-M4 practice, but worth noting in the clock-tree setup.
The STM32F302VET6 has a standard SWD (Serial Wire Debug) interface. Connect SWDIO, SWCLK, GND, and optionally SWO to an ST-Link/V2 or ST-Link/V3 programmer. The target runs from its own supply (2.0 V to 3.6 V). STM32CubeProgrammer or any ARM-compatible debugger (Keil, IAR, STM32CubeIDE) can flash and debug through the SWD port.
