STMicroelectronics STM32F401VEH6

Overview

STM32F401VEH6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating up to 84 MHz, featuring 512 KB Flash, 96 KB SRAM, one 12-bit 2.4 MSPS ADC (16 channels), USB 2.0 FS OTG controller with on-chip PHY, and 81 GPIOs (78 fast I/Os, all 5 V-tolerant). It targets embedded control in industrial HMI, sensor hubs, and portable medical devices requiring real-time signal processing and low-power operation.

For engineers reviewing the STM32F401VEH6 datasheet, STM32F401VEH6 pinout, STM32F401VEH6 application, or STM32F401VEH6 equivalent, key selection criteria include Flash/SRAM size, USB OTG capability, 5 V-tolerant I/O support, ART Accelerator-enabled zero-wait-state execution, and verified low-power modes (down to 2.4 µA Standby, 10 µA Stop with Deep Power Down).

Technical Context

The device integrates an adaptive real-time accelerator (ART Accelerator) enabling deterministic 0-wait-state execution from Flash at 84 MHz, paired with a memory protection unit (MPU) for secure task isolation. Its clock system includes dual oscillators (4–26 MHz HSE + 32 kHz LSE), internal 16 MHz/32 kHz RC with calibration, and dedicated audio PLL (PLLI2S) for I2S audio-class timing.

Peripheral architecture features a multi-AHB bus matrix supporting concurrent DMA transfers across 16-stream controllers, nested vectored interrupt controller (NVIC) with 92 interrupt lines, and advanced connectivity including SDIO, three I2C (SMBus/PMBus), three USART (up to 10.5 Mbit/s), four SPI (up to 42 Mbit/s), and USB OTG FS with integrated PHY - all accessible via 81 GPIOs with interrupt capability.

FAQ

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

The STM32F401VEH6 achieves 84 MHz maximum CPU frequency using its internal PLL driven by the HSE (4–26 MHz crystal) or HSI (16 MHz RC). The ART Accelerator enables zero-wait-state execution from Flash at this speed, confirmed by Dhrystone 2.1 benchmarking at 105 DMIPS. No external clock source beyond the configured oscillator is required.

Does this MCU support USB device functionality without external components?

Yes. The STM32F401VEH6 integrates a full-speed USB 2.0 OTG controller with on-chip PHY, requiring only standard USB termination resistors (1.5 kΩ pull-up on DP) and proper PCB layout. No external transceiver, level shifter, or voltage regulator is needed for basic USB device enumeration and data transfer.

How many I/O pins are 5 V-tolerant and why does it matter?

All 81 GPIOs are 5 V-tolerant, meaning they safely accept 5 V logic inputs even when VDD is as low as 1.7 V. This eliminates external level-shifting circuitry when interfacing with common 5 V peripherals such as RS-232 transceivers, industrial sensors, or legacy microcontrollers - reducing BOM cost, board area, and signal integrity risk.

What low-power modes are supported and what are their typical currents?

It supports Run (146 µA/MHz), Stop (10 µA typical in Deep Power Down mode), and Standby (2.4 µA at 25 °C, 1.7 V). Stop mode retains SRAM and register content with fast wake-up; Standby powers down entire system except RTC and backup registers. All values are measured per official ST datasheet DS10086 Rev 5, Section 6.3.7.
