STMicroelectronics STM32F412VEH3TR

Overview

STM32F412VEH3TR 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 at up to 100 MHz, delivers 125 DMIPS, and supports BAM (Batch Acquisition Mode) for sensor hub applications in wearable and connected devices.

For engineers reviewing the STM32F412VEH3TR datasheet, STM32F412VEH3TR pinout, STM32F412VEH3TR application, or STM32F412VEH3TR equivalent, key selection criteria include its 100 MHz Cortex-M4+FPU core, dual CAN 2.0B support, 1 MB flash density, low-power Stop mode (18 µA), and UFBGA100 package compatibility with high I/O count (109 fast GPIOs).

Technical Context

The device integrates an Adaptive Real-time Accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash at 100 MHz, and features a flexible static memory controller supporting NOR/PSRAM/SRAM with 16-bit bus width. Its dual-mode Quad-SPI interface enables direct XIP or memory-mapped external flash access.

It includes two independent CAN 2.0B controllers, four USARTs (two at 12.5 Mbit/s), five SPI/I2S peripherals (two full-duplex I2S), SDIO, USB OTG FS with integrated PHY, and a 12-bit 2.4 MSPS ADC with up to 16 channels - all synchronized via a multi-AHB bus matrix and 16-stream DMA controller.

FAQ

What is the maximum operating frequency and associated performance metric?

The STM32F412VEH3TR operates at up to 100 MHz with an ART Accelerator™ enabling zero-wait-state Flash execution. Its performance is rated at 125 DMIPS (Dhrystone 2.1), equivalent to 1.25 DMIPS/MHz. This is verified under VDD = 3.6 V, ambient temperature 25 °C, and with ART enabled - critical for deterministic real-time control loops.

Does this MCU support external memory expansion, and what interfaces are available?

Yes, it supports external memory via the Flexible Static Memory Controller (FSMC) with up to 16-bit data bus for NOR, PSRAM, and SRAM, plus a dual-mode Quad-SPI interface for serial flash/XIP. The FSMC is validated for use with common PSRAM devices (e.g., AP Memory APS6248L) and NOR flashes (e.g., Macronix MX29GL), enabling frame buffers or code overlays without external logic.

How many CAN interfaces does the STM32F412VEH3TR provide, and what protocol versions are supported?

The STM32F412VEH3TR integrates two independent bxCAN controllers compliant with ISO 11898-1:2003 (CAN 2.0B Active), supporting both standard (11-bit) and extended (29-bit) identifiers, bit rates up to 1 Mbit/s, and loopback/self-test modes. Both controllers have dedicated TX/RX pins and share no register conflict - enabling simultaneous CAN FD-ready hardware design with software upgrade path.

What are the lowest power consumption modes and their typical current draw?

In Stop mode with Flash in Deep Power Down, it draws 18 µA typical at 25 °C; Standby mode consumes 2.4 µA (no RTC) or 12 µA (at 85 °C). These values are measured per DS11139 Rev 9, Table 31–34, with VDD = 1.7 V, all clocks gated, and regulators configured per Section 3.21. Wakeup time from Stop is <5 µs, enabling rapid response to external interrupts.
