STMicroelectronics STM32F411VEH6U

Overview

STM32F411VEH6U from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 100 MHz max CPU frequency, 512 KB Flash, 128 KB SRAM, and integrated USB OTG FS controller. It delivers 125 DMIPS performance with ART Accelerator enabling zero-wait-state execution from flash, supports 12-bit 2.4 MSPS ADC (16 channels), and operates across -40°C to +105°C for industrial motor control and sensor hub applications.

For engineers reviewing the STM32F411VEH6U datasheet, STM32F411VEH6U pinout, STM32F411VEH6U application, or STM32F411VEH6U equivalent, key selection criteria include Flash/SRAM capacity, USB OTG FS integration, low-power Stop mode current (9 µA in Deep power down), and 77 5 V-tolerant I/Os for mixed-voltage system interfacing.

Technical Context

The STM32F411VEH6U implements an adaptive real-time memory accelerator (ART Accelerator) that eliminates flash wait states at 100 MHz, enabling deterministic code execution. Its dual-bank Flash architecture supports read-while-write operations, and the embedded 128 KB SRAM includes hardware parity checking for safety-critical data buffers.

It integrates a dedicated audio PLL (PLLI2S) for high-fidelity I2S audio clock generation up to 192 kHz sample rates, alongside a full-speed USB 2.0 OTG controller with on-chip PHY-enabling host/device/OTG roles without external transceivers. The 11 timers include two 32-bit units capable of quadrature encoder input and PWM generation with 100 MHz base clock.

FAQ

What is the maximum operating temperature range for STM32F411VEH6U?

The STM32F411VEH6U is rated for industrial operation from -40°C to +105°C ambient temperature, verified per DS10314 Rev 8 Section 6.3.1. This rating applies to the LQFP100 package under specified voltage and load conditions, making it suitable for enclosed industrial cabinets and automotive under-hood auxiliary systems.

Does STM32F411VEH6U 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 using only PA11 (D−) and PA12 (D+) with standard 1.5 kΩ pull-up on D+. No external transceiver, resistors, or crystals are required for basic HID or CDC device operation.

How many 5 V-tolerant I/O pins does STM32F411VEH6U have?

STM32F411VEH6U provides up to 77 5 V-tolerant I/O pins across its GPIO ports (as confirmed in DS10314 Rev 8 Section 3.28), allowing direct interfacing with legacy 5 V logic, industrial sensors, and RS-232 level shifters without external voltage translators.

Is the ART Accelerator enabled by default after reset?

No - the ART Accelerator is disabled after reset and must be explicitly enabled via the ART_CTRL register (address 0x40023C00). Enabling it is required to achieve zero-wait-state execution from Flash at 100 MHz; failure to enable results in 2-wait-state access and degraded real-time performance.
