STMicroelectronics STM32F303VET7

Overview

STM32F303VET7 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 supports CAN 2.0B, USB 2.0 FS, and FSMC for external memory expansion, targeting motor control and industrial sensing systems.

For engineers reviewing the STM32F303VET7 datasheet, STM32F303VET7 pinout, STM32F303VET7 application, or STM32F303VET7 equivalent, key selection criteria include its dual 12-bit DAC channels with 2.4–3.6 V analog supply, 115 fast I/Os (several 5 V-tolerant), 72 MHz FPU-enabled real-time processing, and hardware CRC unit for firmware integrity verification.

Technical Context

The STM32F303VET7 implements an ARM Cortex-M4 core with single-cycle multiplication, hardware division, DSP instructions, and MPU-enabling deterministic real-time control in safety-aware applications. Its analog subsystem integrates four OPAMPs configurable as programmable-gain amplifiers (PGA) with full terminal access and independent 2.4–3.6 V analog supply.

It features a flexible interconnect matrix enabling concurrent peripheral access without bus contention, and supports multiple low-power modes (Sleep, Stop, Standby) with RTC and backup register retention via VBAT. The FSMC provides direct interface to NOR/PSRAM/NAND and PC Card with configurable timing and wait states.

FAQ

What is the maximum operating frequency and does it require external clock sources?

The STM32F303VET7 operates at up to 72 MHz using its internal 8 MHz RC oscillator with PLL multiplication, or optionally from external 4–32 MHz crystal or ceramic resonator. No mandatory external clock is required-internal HSI (8 MHz) or HSE (4–32 MHz) both support full-speed operation with appropriate PLL configuration.

Does the device support hardware-based cryptographic acceleration?

No, the STM32F303VET7 does not include dedicated cryptographic accelerators (e.g., AES, SHA, PKA). It relies on software libraries for encryption; for hardware crypto, consider STM32L4+, STM32H7, or STM32WB series devices with CryptoCell or AES engines.

How many independent 12-bit DAC channels are available and what are their output capabilities?

The STM32F303VET7 integrates two independent 12-bit DAC channels (DAC1 and DAC2) with buffered voltage outputs. Each supports noise shaping, hardware trigger synchronization, and operates with analog supply V_REF+ = 2.4–3.6 V. Output voltage range is 0 to V_REF+, and both channels can generate precise waveforms or DC bias for sensor excitation or actuator control.

Is the LQFP100 package RoHS-compliant and lead-free?

Yes, the STM32F303VET7 in LQFP100 package is RoHS-compliant and lead-free per EU Directive 2011/65/EU and STMicroelectronics' environmental policy. The device carries the "E" suffix in its part number per ST's standard marking convention for lead-free, halogen-free packaging.
