STMicroelectronics STM32F411VET6U

Overview

STM32F411VET6U 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 (16 channels), 11 timers (including six 16-bit and two 32-bit), and 13 communication interfaces-including 3×I²C, 3×USART, 5×SPI/I²S, SDIO, and USB OTG-targeting real-time motor control and sensor hub applications in industrial PLCs and medical equipment.

Technical Context

The STM32F411VET6U implements an Arm Cortex-M4 core with hardware FPU and adaptive real-time accelerator (ART) 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.

Power architecture features dynamic efficiency line with Batch Acquisition Mode (BAM), supporting 1.7–3.6 V operation across –40°C to +105°C, and multiple low-power states: Stop mode down to 9 µA (Flash in deep power-down), Standby at 1.8 µA (no RTC), and VBAT RTC backup at 1 µA.

FAQ

What is the maximum operating temperature range for STM32F411VET6U?

The STM32F411VET6U is rated for operation from –40°C to +105°C ambient temperature. This extended industrial grade rating is confirmed in Section 6.3.1 of the DS10314 Rev 8 datasheet and applies to all LQFP100 variants. Thermal derating begins above 105°C, and junction temperature must remain below 125°C under sustained load.

Does STM32F411VET6U support external memory interfaces like FSMC or OCTOSPI?

No, the STM32F411VET6U does not include FSMC (Flexible Static Memory Controller) or OCTOSPI peripherals. Unlike higher-end F4 models (e.g., STM32F429), it lacks dedicated external memory bus support. All program and data execution occurs from internal Flash and SRAM only-verified in Table 2 and Section 3.5 of DS10314 Rev 8.

Can the internal 16 MHz RC oscillator be used as the system clock source without calibration?

Yes, the internal 16 MHz RC oscillator is factory-trimmed to ±1% accuracy at 25°C and can serve as the system clock source without external trimming. However, its drift over temperature and voltage is ±3% across the full operating range (–40°C to +105°C, 1.7–3.6 V), as specified in Table 39 of DS10314 Rev 8-making it suitable for non-critical timing but not for USB or RTC.

How many independent PWM outputs can STM32F411VET6U generate simultaneously?

The STM32F411VET6U supports up to 32 independent PWM outputs: six 16-bit timers (TIM3–TIM5, TIM8–TIM12) and two 32-bit timers (TIM2, TIM4) each provide up to four complementary PWM channels with dead-time insertion. This is confirmed in Section 3.20 and Table 4 of DS10314 Rev 8, enabling multi-phase motor control and LED matrix dimming.
