72 MHz Cortex-M4 — what the FPU and memory mean for the BOM
The STM32F302VCT7: The Cortex-M4 core with single-precision floating-point unit handles real-time math without a separate DSP coprocessor. The 72 MHz clock is the ceiling for this density tier.
100-LQFP — layout and assembly notes
The 100-LQFP (14x14 mm) is a hand-solderable QFP — no BGA reflow required, which simplifies prototype rework and low-volume production. The 87 I/O count gives plenty of headroom for parallel buses, multiple UARTs, and sensor arrays.
