Product details

Overview

STM32F412VET6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 100 MHz max CPU frequency, 1 MB Flash, 256 KB SRAM, and integrated USB OTG FS, dual CAN 2.0B, and 17 communication interfaces. It delivers 125 DMIPS performance and supports real-time motor control, sensor hub, and industrial HMI applications.

For engineers reviewing the STM32F412VET6 datasheet, STM32F412VET6 pinout, STM32F412VET6 application, or STM32F412VET6 equivalent, key selection criteria include its 100 MHz ART Accelerator™-enabled flash execution, 12-bit 2.4 MSPS ADC with up to 16 channels, low-power Stop mode (18 µA), dual CAN support, and LQFP100 package compatibility for industrial PCB layout.

Technical Context

The STM32F412VET6 integrates an Adaptive Real-Time Accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash at 100 MHz, and Batch Acquisition Mode (BAM) for ultra-low-power peripheral data capture. Its memory subsystem includes flexible static memory controller (FSMC) supporting NOR/PSRAM and dual-mode Quad-SPI for external flash expansion.

It features a full-featured clock system with four oscillators (4–26 MHz HSE, 32 kHz LSE, 16 MHz HSI, 32 kHz LSI), three PLLs (including audio PLL for I2S), and dynamic voltage scaling across Run/Stop/Standby modes. The NVIC supports 92 programmable interrupts with priority grouping, and the 114 GPIOs include 109 fast I/Os (100 MHz) and 114 5 V-tolerant pins.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32F407VGT6	Same LQFP100 package, but lacks BAM, DFSDM, and USB OTG host capability; 1 MB Flash, 192 KB RAM.	No native PDM/microphone support; less suitable for audio-aware edge nodes or battery-constrained sensor hubs.	Select when legacy codebase compatibility or lower-cost USB device-only operation is prioritized over advanced low-power acquisition.
STM32F429ZIT6	Higher integration: 2 MB Flash, 256 KB RAM, Chrom-ART accelerator, FMC for SDRAM, and LCD-TFT controller.	Targeted at high-resolution GUI applications; larger die size and higher active power vs. STM32F412VET6.	Choose for embedded displays requiring >800×480 resolution and hardware-accelerated graphics-accepting trade-off in power and cost.

Compared with STM32F407VGT6, the STM32F412VET6 adds BAM and DFSDM for ultra-low-power sensor acquisition, while versus STM32F429ZIT6 it trades display acceleration for tighter power envelope and smaller footprint-making it optimal for intelligent edge nodes where compute efficiency and peripheral flexibility outweigh raw graphics throughput.

FAQ

What is the maximum operating temperature range for STM32F412VET6?

The STM32F412VET6 is rated for industrial temperature range: –40 °C to +85 °C ambient. Its thermal characteristics (θ_JA = 37.5 °C/W in LQFP100) ensure reliable operation under continuous 100 MHz CPU load with standard PCB copper pour and airflow. No derating is required within this range per datasheet Section 7.10.

Does STM32F412VET6 support external SDRAM via FSMC?

No. The Flexible Static Memory Controller (FSMC) in STM32F412VET6 supports only SRAM, PSRAM, and NOR flash-not SDRAM or NAND flash. SDRAM support requires the enhanced FMC peripheral found in STM32F42x/46x lines. This distinction is confirmed in Section 3.11 of DS11139 Rev 9.

Can the USB OTG FS interface operate in host mode without external VBUS sensing?

Yes. STM32F412VET6's USB OTG FS includes an internal VBUS sensing comparator and dedicated ID pin detection logic. When configured in host mode, it monitors VBUS status autonomously and manages session initiation without external circuitry-verified in Section 3.32 and RM0383 reference manual.

How many independent PWM outputs can be generated simultaneously on STM32F412VET6?

Up to 36 independent PWM signals can be generated: twelve 16-bit timers (TIM2–TIM5, TIM9–TIM14) each provide up to 4 channels, and two 32-bit timers (TIM1/TIM8) each offer 4 complementary channels with dead-time insertion. All channels support center-aligned mode and configurable polarity per RM0383 Section 26.4.2.
