STMicroelectronics STM32F412VET3

Overview

STM32F412VET3 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 LQFP100 package.

For engineers reviewing the STM32F412VET3 datasheet, STM32F412VET3 pinout, STM32F412VET3 application, or STM32F412VET3 equivalent, key selection factors include its ART Accelerator™ enabling zero-wait-state flash execution, BAM for low-power sensor acquisition, 12-bit 2.4 MSPS ADC with up to 16 channels, dual CAN support, and VBAT-powered RTC with subsecond accuracy.

Technical Context

The STM32F412VET3 implements an Arm Cortex-M4 core with hardware FPU and DSP instructions, coupled with ST's Adaptive Real-time Accelerator (ART Accelerator™) that eliminates flash wait states at 100 MHz. Its memory subsystem includes 1 MB of embedded Flash with ECC, 256 KB SRAM, and flexible external memory controller supporting NOR/PSRAM/SRAM.

It integrates dual CAN 2.0B controllers, USB OTG FS with integrated PHY, SDIO, five SPI/I2S interfaces (two full-duplex I2S), four USARTs (two at 12.5 Mbit/s), four I²C, and advanced analog features including a 12-bit 2.4 MSPS ADC, DFSDM with PDM microphone support, and true random number generator.

Key Specifications

FAQ

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

The STM32F412VET3 achieves 100 MHz maximum CPU frequency using its internal PLL with HSE or HSI as source. The ART Accelerator™ ensures zero-wait-state execution from Flash memory at this speed, verified per DS11139 Rev 9 Section 3.2. This eliminates instruction fetch bottlenecks without requiring code relocation to SRAM.

Does STM32F412VET3 include an integrated USB PHY?

Yes, the STM32F412VET3 integrates a full-speed USB 2.0 OTG PHY compliant with USB specification revision 2.0. This eliminates the need for an external transceiver and supports device, host, and OTG roles - confirmed in Section 3.32 and Table 2 of DS11139 Rev 9.

How many CAN interfaces does it support and what protocol versions?

The STM32F412VET3 integrates two independent bxCAN controllers supporting CAN 2.0B protocol exclusively - not CAN FD. Each supports bit rates up to 1 Mbps, programmable timing, and 14 message mailboxes. This is documented in Section 3.31 and Table 2 of the datasheet.

What low-power modes are supported and their typical current draw?

It supports Run, Sleep, Stop (with Flash in Stop or Deep Power Down), and Standby modes. Typical currents: Run = 112 µA/MHz (peripheral off), Stop (fast wake) = 50 µA at 25 °C, Standby = 2.4 µA (no RTC) at 25 °C - all specified in Section 3.21 and Table 31–34 of DS11139 Rev 9.
