Product details
Overview
STM32F412VGT6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 100 MHz max clock, 1 MB Flash, 256 KB SRAM, and integrated USB OTG FS, dual CAN 2.0B, and 17 communication interfaces. It delivers 125 DMIPS and supports real-time motor control, sensor hub processing, and industrial HMI in compact LQFP100 packaging.
For engineers reviewing the STM32F412VGT6TR datasheet, STM32F412VGT6TR pinout, STM32F412VGT6TR application, or STM32F412VGT6TR equivalent, key selection criteria include its 100 MHz Cortex-M4+FPU core, dual CAN support, 1 MB flash with ART Accelerator™ for zero-wait-state execution, low-power Stop mode (18 µA), and full-speed USB OTG capability with embedded PHY.
Technical Context
The device integrates an Adaptive Real-time Accelerator (ART Accelerator™) enabling deterministic 0-wait-state execution from Flash at 100 MHz. Its memory subsystem includes flexible external static memory controller (FSMC) supporting SRAM, PSRAM, and NOR, plus dual-mode Quad-SPI for high-speed serial flash.
Peripherals are organized around a multi-AHB bus matrix with 16-stream DMA, enabling concurrent high-bandwidth transfers. The dual CAN 2.0B controllers operate independently with dedicated message RAM, while the USB OTG FS controller embeds a full-speed PHY and supports device/host/OTG roles without external transceivers.

FAQ
What is the function of VCAP_1 and VCAP_2 pins on STM32F412VGT6TR?
VCAP_1 and VCAP_2 are dedicated pins for connecting 2.2 µF ceramic decoupling capacitors to the internal 1.2 V voltage regulator. These capacitors stabilize the core supply during dynamic load changes; omitting them or using incorrect values prevents reliable boot and may cause erratic behavior or brown-out resets under load.
Does STM32F412VGT6TR support USB device, host, and OTG simultaneously?
No - the USB OTG FS controller supports device, host, or OTG modes, but only one at a time. Mode selection is controlled by software configuration of the USB_OTG_GCCFG register and physical ID pin state. Dual-role operation requires external ID detection circuitry and firmware state management.
Can the 12-bit ADC achieve its full 2.4 MSPS sampling rate across all 16 channels?
No - 2.4 MSPS is the maximum single-channel sampling rate. When scanning multiple channels in sequence, effective throughput decreases due to sampling time, conversion latency, and DMA transfer overhead. For 16-channel continuous scan, practical sustained rate is ~150 kSPS per channel with proper clock and prescaler tuning.
Is the LQFP100 package of STM32F412VGT6TR RoHS and REACH compliant?
Yes - the LQFP100 package is ECOPACK2 certified, meeting both RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006 requirements. Lead-free matte tin finish, halogen-free molding compound, and fully traceable material declarations are provided in ST's official compliance documentation.
