STMicroelectronics STM32F411VEH6TR

Overview

STM32F411VEH6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 100 MHz max CPU frequency, 512 KB Flash, 128 KB SRAM, and USB OTG FS controller. It integrates a 12-bit 2.4 MSPS ADC, 11 timers (including two 32-bit), and up to 13 communication interfaces including 3×I²C, 3×USART, 5×SPI/I²S, SDIO, and OTG_FS - deployed in industrial PLCs, motor drives, and medical sensor hubs.

For engineers reviewing the STM32F411VEH6TR datasheet, STM32F411VEH6TR pinout, STM32F411VEH6TR application, or STM32F411VEH6TR equivalent, key selection factors include its 100 MHz ART-accelerated flash execution, 9 µA Stop mode power consumption, 77 5 V-tolerant I/Os, and integrated audio PLL for I²S-class audio timing.

Technical Context

The device implements an Arm Cortex-M4 core with floating-point unit and adaptive real-time (ART) accelerator enabling zero-wait-state execution from Flash at 100 MHz. Its memory subsystem includes 512 KB of embedded Flash and 128 KB of SRAM, with MPU support for secure task isolation.

Clock architecture features dual oscillators: 4–26 MHz external crystal and factory-trimmed 16 MHz RC, plus dedicated 32 kHz RTC oscillator with calibration. Power management supports five low-power modes - Run, Sleep, Stop (Flash in Stop/Deep power down), and Standby - with sub-µA RTC backup via VBAT.

FAQ

What is the maximum operating temperature range for STM32F411VEH6TR?

The STM32F411VEH6TR is rated for industrial operation from –40°C to +105°C ambient temperature. This rating applies to all package variants including the UFQFPN48, and is validated per ST's production test flow with derating curves provided in Section 6.3.3 of DS10314 Rev 8.

Does STM32F411VEH6TR support USB device-only mode without external components?

Yes - the part integrates a full-speed USB 2.0 OTG controller with on-chip PHY, enabling USB device mode (e.g., CDC, HID, MSC) using only PA11 (D−) and PA12 (D+) with mandatory 27 Ω series resistors. No external transceiver or termination resistors are required for basic enumeration.

How many I²C interfaces can operate simultaneously in SMBus mode?

All three I²C interfaces (I²C1–I²C3) support SMBus 2.0 packet error checking (PEC), timeout detection, and alert response protocol. They can operate concurrently - for example, I²C1 managing PMBus power supplies, I²C2 reading environmental sensors, and I²C3 controlling display EEPROMs - with independent clock stretching and arbitration.

Is the VCAP capacitor requirement mandatory for stable 100 MHz operation?

Yes - two 2.2 µF X7R ceramic capacitors must be placed directly at VCAP_1 and VCAP_2 pins per Section 7.3 of DS10314 Rev 8. Omitting them causes voltage regulator instability, leading to intermittent crashes or failure to reach 100 MHz reliably, especially under dynamic load or temperature variation.
