What this STM32F302VCT6TR brings to the board
It packs 256 KB of Flash and 40K x 8 of RAM, with 87 I/O lines broken out to a 100-LQFP package.
The 72 MHz core clock is the headline number, but the real value is the single-cycle multiply-accumulate and hardware divider that the Cortex-M4 FPU brings. For a field-oriented motor-control loop or a sensor-fusion algorithm, you get the throughput without pushing the clock to the edge of the timing budget.
87 I/O and the 100-LQFP footprint
With 87 I/O pins in a 100-LQFP (14x14 mm), this MCU gives you the routing flexibility to handle parallel sensor inputs, multiple PWM channels, and a parallel LCD interface without multiplexing. The 14x14 mm body is a standard footprint — no exotic BGA rework station needed.
The ROHS3 compliance is current — no exemption cliff to watch.
