STMicroelectronics STM32F303VET6

Overview

STM32F303VET6 from STMicroelectronics is a 32-bit ARM® Cortex®-M4 microcontroller with FPU, operating at up to 72 MHz, featuring 512 KB Flash, 80 KB SRAM (64 KB + 16 KB CCM), and integrated analog peripherals including four 12-bit ADCs, two 12-bit DACs, seven rail-to-rail comparators, and four operational amplifiers. It targets motor control, digital power conversion, and industrial sensing systems requiring real-time signal processing and mixed-signal integration.

For engineers reviewing the STM32F303VET6 datasheet, STM32F303VET6 pinout, STM32F303VET6 application, or STM32F303VET6 equivalent, key selection considerations include its 100-pin LQFP package, 2.0–3.6 V supply range, dual 12-bit DAC channels, flexible memory controller (FSMC), and CAN 2.0B interface for embedded control networks.

Technical Context

The STM32F303VET6 implements an ARM Cortex-M4 core with hardware floating-point unit (FPU), single-cycle MAC, and DSP instruction set - enabling deterministic execution of motor control algorithms and digital filter routines. Its memory protection unit (MPU) supports secure task isolation in RTOS environments.

Analog subsystem integration includes four independent 12-bit ADCs (0.20 µs conversion, up to 40 channels), two synchronized 12-bit DACs (2.4–3.6 V analog supply), and four op-amps configurable as programmable gain amplifiers (PGAs) - all sharing a common interconnect matrix for low-latency peripheral coordination.

FAQ

What is the maximum operating frequency and core type of the STM32F303VET6?

The STM32F303VET6 features an ARM Cortex-M4 core with hardware FPU, running at a maximum frequency of 72 MHz. It delivers 90 DMIPS performance and supports single-cycle multiplication and hardware division. The FPU enables efficient execution of floating-point computations essential for motor control algorithms and digital signal processing tasks.

Does the STM32F303VET6 support hardware-based deadtime insertion for motor control PWM outputs?

Yes, the STM32F303VET6 includes three advanced-control timers (TIM1, TIM8, TIM20) that provide hardware-configurable deadtime insertion (1–1023 ns resolution) on complementary PWM outputs. This feature prevents shoot-through in half-bridge and three-phase inverter topologies without requiring external logic or software compensation.

What analog peripherals are integrated into the STM32F303VET6 and what are their key electrical specifications?

The device integrates four 12-bit ADCs (0.20 µs conversion time, up to 40 input channels), two 12-bit DACs (2.4–3.6 V analog supply), seven rail-to-rail comparators, and four operational amplifiers usable in PGA mode. All analog blocks share independent VDDA/VSSA supplies and support 2.0–3.6 V operation, with op-amp gains configurable from 1 to 128 in hardware.

Is the STM32F303VET6 pin-compatible with other members of the STM32F303xD/E family?

Yes, the STM32F303VET6 in LQFP100 is pin-compatible with other STM32F303xE devices in the same package (e.g., STM32F303RET6, STM32F303ZET6), differing only in Flash/RAM size and peripheral enablement. Pin mappings for power, clocks, reset, debug, and common peripherals remain identical - enabling scalable design reuse across performance tiers.
