STMicroelectronics STM32F401VBH6

Overview

STM32F401VBH6 from STMicroelectronics is an Arm® Cortex®-M4 32-bit microcontroller with FPU, delivering 105 DMIPS at 84 MHz, featuring 256 KB Flash, 64 KB SRAM, one 12-bit 2.4 MSPS ADC (16 channels), and USB 2.0 FS OTG controller - deployed in industrial HMI, sensor fusion nodes, and portable medical devices requiring deterministic real-time response and low-power operation.

For engineers reviewing the STM32F401VBH6 datasheet, STM32F401VBH6 pinout, STM32F401VBH6 application, or STM32F401VBH6 equivalent, key selection criteria include ART Accelerator™-enabled zero-wait-state Flash execution, 5 V-tolerant GPIOs (up to 78 at 42 MHz), BAM (Batch Acquisition Mode) for sensor data capture, and integrated USB PHY supporting device/host/OTG roles without external transceiver.

Technical Context

The STM32F401VBH6 implements a tightly coupled Cortex-M4 core with hardware FPU and Memory Protection Unit (MPU), paired with the Adaptive Real-time Accelerator (ART Accelerator™) that eliminates Flash wait states up to 84 MHz - enabling deterministic interrupt latency and efficient DSP instruction execution. Its clock system integrates dual oscillators (4–26 MHz HSE + 32 kHz LSE), internal 16 MHz HSI and 32 kHz LSI, plus main PLL and audio PLL (PLLI2S) for independent peripheral clock domains.

Power architecture supports five low-power modes: Run (128 µA/MHz), Stop with fast wakeup (42 µA typ), Stop with deep power-down (10 µA typ), Standby (2.4 µA @25°C), and VBAT RTC mode (1 µA). All 81 GPIOs are 5 V tolerant, with up to 78 capable of 42 MHz toggle; DMA includes 16-stream controller with FIFO and burst support for high-throughput peripheral offload.

FAQ

Does STM32F401VBH6 support USB device mode without external PHY?

Yes. The part integrates a full-speed USB 2.0 OTG PHY compliant with USB specification rev 2.0. It supports device, host, and OTG roles using only the internal DP/DM transceivers and standard 1.5 kΩ pull-up resistor - no external PHY chip or level shifter required.

What is the maximum ADC sampling rate achievable with DMA in BAM mode?

In Batch Acquisition Mode with DMA enabled, the 12-bit ADC achieves up to 2.4 MSPS across 16 channels. With single-channel configuration and optimized timing, sustained throughput reaches 2.4 million samples per second - verified in DS9716 Section 3.28 and electrical characteristics Table 66.

How many GPIOs are available in the UFQFPN48 package of STM32F401VBH6?

The UFQFPN48 package provides 42 user-accessible GPIOs (PA0–PA15, PB0–PB15, PC13–PC15, PH0–PH1), confirmed in DS9716 Section 4 pinout table and Table 8. All are 5 V tolerant and support alternate functions including USART, SPI, I²C, and timer channels.

Is the ART Accelerator™ active by default after reset?

Yes. The ART Accelerator™ is enabled by default upon power-on reset and remains active unless explicitly disabled via SYSCFG register (SYSCFG_MEMRMP[1]). It operates transparently to accelerate Flash access - no software initialization is required to achieve zero-wait-state execution at 84 MHz.
