STMicroelectronics STM32F401VEH7

Overview

STM32F401VEH7 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, delivering 105 DMIPS at 84 MHz, featuring 512 KB Flash, 96 KB SRAM, and integrated USB OTG FS controller with on-chip PHY. It supports 12 communication interfaces including 3×I²C, 3×USART, 4×SPI/I²S, SDIO, and advanced timer peripherals - deployed in industrial HMI, portable medical sensors, and USB-connected edge nodes.

For engineers reviewing the STM32F401VEH7 datasheet, STM32F401VEH7 pinout, STM32F401VEH7 application, or STM32F401VEH7 equivalent, key selection considerations include its 100-pin LQFP package, 1.7–3.6 V supply range, 5 V-tolerant I/Os, ART Accelerator for zero-wait-state flash execution, and RTC with subsecond accuracy - all critical for real-time embedded control and low-power connectivity designs.

Technical Context

The device implements an Arm Cortex-M4 core with hardware FPU and DSP instruction set, coupled with ST's Adaptive Real-Time (ART) Accelerator to eliminate flash wait states at 84 MHz. Its memory subsystem includes 512 KB of dual-bank Flash with ECC support and 96 KB of SRAM, partitioned across AHB/APB buses via a multi-layer bus matrix.

Peripherals are clocked via multiple domain-specific prescalers: APB1 (≤42 MHz) for timers and I²C, APB2 (≤84 MHz) for GPIO and USART, and dedicated audio PLL (PLLI2S) for I²S sampling. Power management integrates five low-power modes (Sleep, Stop, Standby, VBAT, and Shutdown), with wake-up from Stop mode in ≤5 µs using internal RC or external crystal sources.

FAQ

What is the maximum operating temperature for STM32F401VEH7?

The device is qualified for industrial temperature range: –40 °C to +85 °C ambient. Electrical characteristics in DS10086 Rev 5 are guaranteed across this range, including 10 µA Stop mode current and 84 MHz CPU operation - validated per JEDEC JESD47 stress testing protocols.

Does STM32F401VEH7 support external memory interfaces like SDRAM or NOR Flash?

No. The STM32F401VEH7 lacks FSMC (Flexible Static Memory Controller) or Quad-SPI peripheral. It supports only internal Flash and SRAM, plus SDIO for removable storage. External parallel memory expansion requires STM32F407 or higher-series MCUs.

Can the USB OTG FS port operate in Host mode without external VBUS sensing?

Yes. The USB OTG FS controller includes integrated VBUS detection circuitry and supports Session Request Protocol (SRP) and Host Negotiation Protocol (HNP). No external comparator or GPIO-based sensing is required for basic host negotiation.

Is the 96-bit unique ID accessible via standard HAL libraries?

Yes. STM32Cube HAL provides HAL_GetUID() API returning the 96-bit identifier as three 32-bit words. This value is factory-programmed, read-only, and usable for secure boot binding, device licensing, or anti-cloning measures without custom register access.
