Active Cortex-M4 with 512 KB flash — the BOM-fit baseline
The STM32F303VEH6 is an active-production ARM Cortex-M4 MCU from the STM32F3 series, running at 72 MHz with 512 KB flash and 80 KB SRAM. It is the part to specify when the design needs a single-core DSP-capable core with a rich analog peripheral set — the 39-channel 12-bit ADC and dual 12-bit DAC let you close current-sense and voltage-feedback loops without external converters.
Memory and peripheral headroom for sensor-fusion firmware
512 KB of on-chip flash (512K x 8) leaves room for a full motor-control stack plus sensor-fusion libraries; the 80 KB SRAM supports multiple frame buffers for real-time signal processing. The 84 I/O lines break out across the 100-UFBGA package, with connectivity including CAN, I2C, SPI, UART/USART, and USB — enough to interface with fieldbus gateways, encoders, and external ADCs on a single board.
Tray packaging means the parts arrive in antistatic trays, not tape-and-reel — plan for pick-and-place feeder setup accordingly.
