STMicroelectronics STM32F412VGH6

Overview

STM32F412VGH6 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 performance and supports advanced low-power modes (down to 2.4 µA in Standby), making it suitable for battery-powered sensor hubs and industrial edge nodes requiring real-time control and connectivity.

For engineers reviewing the STM32F412VGH6 datasheet, STM32F412VGH6 pinout, STM32F412VGH6 application, or STM32F412VGH6 equivalent, key selection considerations include its 100 MHz Cortex-M4+FPU core, dual CAN support, 12-bit 2.4 MSPS ADC with up to 16 channels, DFSDM for sigma-delta audio input, and UFBGA100 (7×7 mm) package with 109 fast I/Os rated to 100 MHz.

Technical Context

This MCU 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 without CPU wake-up. Its memory subsystem includes flexible FSMC for NOR/PSRAM and dual-mode Quad-SPI for high-speed external memory expansion.

The device features dual CAN 2.0B controllers, USB OTG FS with integrated PHY, four I²C (SMBus/PMBus), four USARTs (two at 12.5 Mbit/s), five SPI/I²S (two full-duplex I²S), SDIO, and two digital filters for sigma-delta modulators - supporting stereo PDM microphone interfaces and real-time audio preprocessing.

Key Specifications

Pinout & Package

STM32F412VGH6 uses the UFBGA100 (7 × 7 mm, 0.5 mm pitch) package with 100 balls. Pin assignment follows ST's standard STM32F412xG ballout layout, including dedicated VCAP_1/VCAP_2 decoupling pins, dual VDD/VSS power domains, and configurable alternate-function mapping per GPIO.

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32F412VGH6 achieves 100 MHz maximum CPU frequency using its internal PLL with HSE (4–26 MHz) or HSI (16 MHz) as source. The ART Accelerator™ eliminates Flash wait states, enabling deterministic zero-latency instruction fetch. This allows full 125 DMIPS performance without external cache or SRAM, verified under 1.7–3.6 V supply and -40°C to +85°C ambient conditions.

Does STM32F412VGH6 support USB device, host, and OTG simultaneously?

No - the integrated USB OTG FS controller supports device, host, or OTG operation in a single mode per boot cycle, selected via software configuration. Dual-role switching requires firmware reinitialization and external VBUS sensing circuitry. It does not support concurrent device+host operation like some higher-tier STM32H7 parts.

How many ADC channels are available and what is their effective resolution?

The device has one 12-bit ADC with up to 16 external input channels (e.g., PA0–PA5, PB0–PB1, PC0–PC5). At 2.4 MSPS sampling rate, typical ENOB is 11.2 bits; oversampling with hardware averaging can extend effective resolution to 14 bits at reduced throughput (e.g., 600 kSPS with 4× oversample + decimate).

What are the mandatory external components for stable operation?

Mandatory components include two 2.2 µF X7R ceramic capacitors on VCAP_1 and VCAP_2 pins, a 4–26 MHz crystal for HSE (if used), 32.768 kHz crystal for RTC, and 100 nF decoupling caps on each VDD/VDDA pair. The VDDUSB rail requires separate 1 µF + 10 nF filtering. No external reset IC is needed - internal POR/PDR/BOR suffices.
