The Cortex-M4 core includes a single-precision FPU and DSP instructions, so a sensor-fusion algorithm or a PID loop with floating-point coefficients runs without a software emulation layer. The 52 I/O pins in the 64-LQFP package leave headroom for parallel sensor interfaces and a local display or keypad.
Pin-to-pin compatibility within the STM32F302 family
The base product number STM32F302 covers several Flash and temperature variants in the same 64-LQFP footprint. The STM32F302RBT7TR is pin-compatible with the STM32F302RBT6 (same Flash and RAM, commercial temperature range) and with the higher-density STM32F302RCT6 (256 KB Flash). Swapping between these requires only a firmware rebuild — the PCB layout stays identical. The 72 MHz speed grade is consistent across the RBTx and RC Tx variants, so timing closure does not change.
