With 87 I/Os in a 100-pin LQFP, this MCU leaves room for parallel LCD interfaces, multiple UARTs, and CAN bus nodes without sacrificing sensor inputs. The 100-LQFP (14x14 mm) footprint is a standard hand-solderable package, easing prototype rework and low-volume production.

It is not pin-compatible — the STM32L151 uses a smaller 48-pin package and fewer I/Os — so a board redesign is required. For a drop-in replacement within the STM32F3 series, consider pin-compatible density variants sharing the 100-LQFP footprint.
