Product details
Overview
STM32F401VDH6 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, SDIO, and I²S, and targets embedded control applications requiring real-time signal processing and connectivity in space-constrained industrial sensors and IoT edge nodes.
For engineers reviewing the STM32F401VDH6 datasheet, STM32F401VDH6 pinout, STM32F401VDH6 application, or STM32F401VDH6 equivalent, key selection considerations include its 84 MHz Cortex-M4+FPU core, 512 KB flash/96 KB RAM memory configuration, LQFP64 package with 51 GPIOs (78 fast I/Os up to 42 MHz), 12-bit 2.4 MSPS ADC, and low-power Stop mode down to 10 µA - all critical for battery-powered motor control and smart metering designs.
Technical Context
The STM32F401VDH6 implements an Arm Cortex-M4 core with hardware FPU and adaptive real-time accelerator (ART) enabling zero-wait-state execution from Flash at 84 MHz. Its memory subsystem includes 512 KB of embedded Flash, 96 KB SRAM, and 512 bytes OTP, all managed by a Memory Protection Unit (MPU) for secure task isolation.
Peripheral architecture integrates a multi-AHB bus matrix, 16-stream DMA with FIFOs, 11 timers (including six 16-bit and two 32-bit general-purpose units), and dual clock domains supporting independent RTC operation via 32 kHz LSE/LSI oscillators - enabling precise timekeeping during ultra-low-power Stop modes.
Key Specifications

FAQ
What is the maximum operating frequency and core type of the STM32F401VDH6?
The STM32F401VDH6 features an Arm Cortex-M4 core with FPU, rated for a maximum operating frequency of 84 MHz. It delivers 105 DMIPS performance per Dhrystone 2.1 benchmark, enabled by the ART Accelerator that eliminates Flash wait states. The core includes a Memory Protection Unit (MPU) and supports DSP instructions, making it suitable for real-time control and signal processing tasks without external coprocessors.
Does the STM32F401VDH6 include an integrated USB physical layer?
Yes, the STM32F401VDH6 integrates a full-speed USB 2.0 OTG controller with an on-chip PHY. This eliminates the need for external USB transceivers, reducing BOM cost and PCB footprint. The device supports USB device, host, and OTG roles, and requires only a 1.5 kΩ pull-up resistor on the USB_DP line for device enumeration - confirmed in Section 3.26 of the DS10086 datasheet.
How many I/O pins are available in the LQFP64 package, and are they 5 V-tolerant?
The STM32F401VDH6 in LQFP64 provides 51 general-purpose I/O pins, all of which are 5 V-tolerant while operating from a 1.7–3.6 V supply. This allows direct interfacing with legacy 5 V peripherals without external level shifters. Pin functionality is configurable via alternate function registers, supporting up to 12 communication interfaces including USART, SPI, I²C, and USB.
What low-power modes does the STM32F401VDH6 support, and what is the lowest achievable current draw?
The STM32F401VDH6 supports Run, Sleep, Stop, and Standby modes. In Stop mode with Flash in Deep Power Down and RTC active, it achieves as low as 10 µA typical current at 25 °C - verified in Section 6.3.27 of DS10086. This mode retains SRAM content and enables fast wake-up (<3.5 µs) via EXTI lines or RTC alarm, making it ideal for battery-powered sensor nodes requiring periodic measurement and long idle periods.
