The part is in a 100-pin LQFP package with 86 I/O, giving enough headroom for parallel sensor interfaces and parallel PWM outputs without needing a BGA. ## 72 MHz Cortex-M4 with FPU — the loop-rate decider The 72 MHz core speed with a hardware FPU is the headline spec that separates this part from the STM32L1 family. For a motor-control loop running a sensorless FOC observer, the FPU cuts the per-cycle math time roughly in half versus a software-emulated float on a Cortex-M3. ## 512 KB Flash and 80 KB SRAM — firmware-fit check 512 KB of Flash is the mid-density option in the STM32F303Vx line. It holds a full motor-control stack (FOC library, comms stack, bootloader) with room for OTA staging. The 80 KB SRAM is enough for two 256-point FFT buffers plus control variables; if your application needs a large display frame buffer or a TCP/IP stack with multiple sockets, you will bump into the ceiling and need to look at the STM32F4 or external SRAM. ## 39-channel 12-bit ADC — analog front-end density The 39-channel 12-bit ADC is unusually dense for a 100-pin package. It lets you sample three-phase currents, DC-link voltage, and several temperature sensors on a single MCU without external muxes. The two 12-bit DAC channels are useful for analog set-point generation or offset trim in a servo drive. ## Package and storage note The 100-LQFP package has a 14x14 mm body with 0.5 mm pitch — a common footprint that most assembly houses handle without special tooling.","metaTitle":"STM32F303VET6TR STM32F3 ARM Cortex-M4 MCU, 512KB Flash","metaDescription":"STMicroelectronics STM32F303VET6TR 32-bit ARM Cortex-M4 MCU, 512KB Flash, 72MHz, 80K RAM, 100-LQFP.
