72 MHz Cortex-M4 with FPU — real-time control headroom
The STM32F302CBT6 is an STMicroelectronics STM32F3-series 32-bit ARM Cortex-M4 MCU with a single-precision FPU, clocked at 72 MHz. The 9-channel 12-bit ADC and single 12-bit DAC cover typical analog-front-end needs in motor-drive current sensing or battery-charger feedback paths.
48-LQFP package — footprint and layout notes
Housed in a 48-pin LQFP (7x7 mm body), the STM32F302CBT6 is a surface-mount device. The 37 I/O lines are enough for a modest sensor array or parallel interface but not overkill for a compact PCB.
