STMicroelectronics STM32F401VCT7

Overview

STM32F401VCT7 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating up to 84 MHz, featuring 256 KB Flash, 64 KB SRAM, one 12-bit 2.4 MSPS ADC, and 11 communication interfaces including USB OTG FS, SPI, I²C, and USART. It targets embedded control in industrial HMI, sensor hubs, and portable medical devices requiring real-time processing and low-power operation.

For engineers reviewing the STM32F401VCT7 datasheet, STM32F401VCT7 pinout, STM32F401VCT7 application, or STM32F401VCT7 equivalent, key selection factors include its ART Accelerator™ enabling zero-wait-state Flash execution, 5 V-tolerant GPIOs (up to 81 pins), -40 °C to 105 °C extended temperature grade, and integrated USB PHY for host/device/OTG functionality.

Technical Context

The STM32F401VCT7 integrates an Arm Cortex-M4 core with hardware FPU and Adaptive Real-time Accelerator (ART Accelerator™) that eliminates Flash wait states at 84 MHz, delivering 105 DMIPS performance. Its memory subsystem includes 256 KB of dual-bank Flash with ECC support, 64 KB SRAM, and 512 bytes of OTP.

Peripherals are organized via multi-AHB bus matrix and supported by 16-stream DMA with FIFOs. Clocking relies on four oscillators: 4–26 MHz external crystal, 16 MHz factory-trimmed RC, 32 kHz RTC crystal, and 32 kHz internal RC - all with calibration - enabling precise timing across run, stop, and standby modes.

FAQ

What is the maximum operating temperature range for the STM32F401VCT7?

The STM32F401VCT7 is rated for operation from -40 °C to +105 °C ambient temperature, validated per ST's production data sheet DS9716 Rev 11. This extended grade supports deployment in industrial enclosures and automotive under-hood auxiliary modules where thermal margins exceed standard commercial-grade limits.

Does the STM32F401VCT7 support hardware floating-point operations?

Yes - it integrates a single-precision Arm Cortex-M4 FPU compliant with IEEE 754, enabling accelerated trigonometric, exponential, and DSP math functions. The FPU is accessible via CMSIS-DSP library and GCC/ARM compiler intrinsics, with full register stacking during interrupts confirmed in the reference manual RM0368.

Can the STM32F401VCT7 boot directly from its internal SRAM?

No - boot modes are limited to System Memory (for DFU), Embedded Flash, or SRAM *only when configured via BOOT pins and loaded externally*. The device lacks native SRAM-only boot capability; SRAM execution requires prior code loading via debugger or bootloader, as defined in Section 3.12 of DS9716.

Is the USB interface on the STM32F401VCT7 compatible with USB 2.0 High-Speed devices?

No - the integrated USB peripheral is strictly Full-Speed (12 Mbit/s) compliant, supporting USB 2.0 specification only in FS mode. It does not implement High-Speed (480 Mbit/s) transceivers or chirp signaling; external PHYs cannot be added due to lack of ULPI or UTMI+ interface support in this variant.
