STMicroelectronics STM32F412VEH6

Overview

STM32F412VEH6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 1 MB Flash, 256 KB SRAM, USB OTG FS, dual CAN 2.0B, and 17 communication interfaces. It operates up to 100 MHz, delivers 125 DMIPS, and supports LCD parallel interface (8080/6800 modes) for embedded HMI applications in industrial control and connected devices.

For engineers reviewing the STM32F412VEH6 datasheet, STM32F412VEH6 pinout, STM32F412VEH6 application, or STM32F412VEH6 equivalent, key selection criteria include its 100 MHz Cortex-M4+FPU core, dual CAN support, 1 MB flash density, low-power Stop mode (18 µA), and LQFP100 package compatibility with legacy STM32F4 designs.

Technical Context

The STM32F412VEH6 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 sensor 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 12-bit, 2.4 MSPS ADC with up to 16 channels, two digital filters for sigma-delta modulators (DFSDM), four PDM interfaces for stereo microphone input, and hardware RTC with subsecond accuracy and calendar function - all tightly coupled to the Cortex-M4 core via multi-AHB bus matrix for deterministic latency.

FAQ

What is the maximum operating frequency and associated performance metric?

The STM32F412VEH6 runs at up to 100 MHz with its Arm Cortex-M4 core and achieves 125 DMIPS (Dhrystone 2.1), measured at 1.25 DMIPS/MHz. This performance is sustained with zero wait states from Flash memory thanks to the integrated ART Accelerator™, making it suitable for real-time control and signal processing tasks without external memory bottlenecks.

Does this MCU support external memory interfaces, and which types are supported?

Yes, the STM32F412VEH6 includes a Flexible Static Memory Controller (FSMC) supporting 16-bit parallel interfaces to SRAM, PSRAM, and NOR flash memory. It also features a dual-mode Quad-SPI interface for high-speed serial flash expansion. These interfaces enable direct connection to external displays, FPGA co-processors, or large code/data storage without external glue logic.

How many CAN interfaces does the STM32F412VEH6 provide, and what protocol versions are supported?

The STM32F412VEH6 integrates two independent bxCAN 2.0B controllers, each supporting full CAN 2.0B protocol with 29-bit identifiers, programmable bit timing, and hardware message filtering. Both controllers operate concurrently and can be configured for redundancy, multi-network routing, or gateway functions in industrial automation and automotive subsystems.

What low-power modes are available, and what is the lowest achievable current draw?

The STM32F412VEH6 offers Run, Sleep, Stop (with Flash in Deep Power Down), and Standby modes. The lowest active current is 18 µA in Stop mode with Flash in Deep Power Down and slow wakeup (25 °C), and 2.4 µA in Standby mode without RTC (25 °C, 1.7 V). VBAT operation enables RTC and backup registers at just 1 µA.
