STMicroelectronics STM32F412VGT6

Overview

STM32F412VGT6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 MCU 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 BAM for low-power sensor hub and industrial control applications requiring real-time signal processing and connectivity.

For engineers reviewing the STM32F412VGT6 datasheet, STM32F412VGT6 pinout, STM32F412VGT6 application, or STM32F412VGT6 equivalent, key selection criteria include its 100 MHz Cortex-M4+FPU core, dual CAN support, 12-bit 2.4 MSPS ADC, 114 I/Os (109 at 100 MHz), and ECOPACK2-compliant LQFP100 package with VBAT RTC backup capability.

Technical Context

The device integrates an Adaptive Real-time Accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash at 100 MHz, alongside Batch Acquisition Mode (BAM) for ultra-low-power peripheral data capture without CPU wake-up. Its memory subsystem includes flexible FSMC for NOR/PSRAM and dual-mode Quad-SPI for high-speed external memory expansion.

Peripherals are organized around a multi-AHB bus matrix supporting concurrent DMA transfers across 16-stream controller, with dedicated audio paths via PLLI2S and DFSDM sigma-delta filters. The bxCAN controllers operate in 2.0B Active mode with full mailbox support, and USB OTG FS includes integrated PHY for device/host/OTG operation without external transceivers.

FAQ

What is the maximum operating frequency and core architecture of the STM32F412VGT6?

The STM32F412VGT6 features an Arm Cortex-M4 core with integrated FPU, rated for up to 100 MHz operation. It achieves 125 DMIPS performance (1.25 DMIPS/MHz) under Dhrystone 2.1 benchmark, supported by the ART Accelerator™ for zero-wait-state Flash execution. The core includes a Memory Protection Unit (MPU) and full DSP instruction set for real-time signal processing tasks.

Does the STM32F412VGT6 support true low-power sensor acquisition without CPU intervention?

Yes-it implements Batch Acquisition Mode (BAM), allowing peripherals like the 12-bit ADC, DFSDM, and USART to autonomously acquire and pre-process data while the CPU remains in Stop or Standby mode. Data is stored in SRAM or FIFOs, and the CPU wakes only upon buffer threshold, completion, or error condition-reducing average system power significantly in sensor-hub applications.

How many CAN interfaces does the STM32F412VGT6 provide, and what protocol versions are supported?

The STM32F412VGT6 integrates two independent bxCAN controllers compliant with ISO 11898-1:2003 (CAN 2.0B Active). Each supports standard and extended identifiers, 14 message mailboxes, programmable bit timing, and automatic retransmission. Both controllers operate concurrently and can be configured for different baud rates, enabling dual-bus diagnostics or redundant fieldbus communication.

What package type and pin count does the STM32F412VGT6 use, and is it RoHS/ECOPACK2 compliant?

The STM32F412VGT6 uses the LQFP100 package: 100-pin, 14×14 mm body, 0.5 mm pitch, with exposed thermal pad. It is fully ECOPACK2-compliant (halogen-free, lead-free, RoHS-aligned) per STMicroelectronics documentation (DS11139 Rev 9, Section 7.5). This package supports robust thermal dissipation and straightforward PCB layout for industrial-grade designs.
