Product details
Overview
STM32F411RCT6 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 1.7–3.6 V supply, and operates across –40°C to +105°C for industrial motor control and sensor hub applications.
For engineers reviewing the STM32F411RCT6 datasheet, STM32F411RCT6 pinout, STM32F411RCT6 application, or STM32F411RCT6 equivalent, key selection criteria include its 100 MHz Cortex-M4+FPU core, 512 KB flash/128 KB SRAM memory configuration, USB OTG FS with on-chip PHY, 12-bit 2.4 MSPS ADC (16 channels), and low-power Stop mode down to 9 µA - all in LQFP64 package.
Technical Context
The device implements an adaptive real-time memory accelerator (ART Accelerator) that eliminates flash wait states at 100 MHz, enabling deterministic code execution. Its power architecture includes Batch Acquisition Mode (BAM) for ultra-low-power peripheral operation and three low-power modes (Stop, Standby, VBAT) with sub-µA RTC support.
Peripherals are organized via multi-AHB bus matrix and 16-stream DMA with FIFOs. Clock system integrates four oscillators: 4–26 MHz HSE, 16 MHz HSI, 32 kHz LSE for RTC, and 32 kHz LSI - all feeding dual PLLs (main PLL and audio PLLI2S) for precise domain-specific clock generation.

FAQ
What is the maximum operating frequency and how is it achieved?
The STM32F411RCT6 achieves 100 MHz CPU frequency using its Arm Cortex-M4 core with FPU and Adaptive Real-Time (ART) Accelerator. The ART Accelerator employs prefetch and branch cache to eliminate flash wait states, enabling deterministic zero-wait-state execution directly from 512 KB on-chip Flash memory under 1.7–3.6 V supply conditions.
Does this MCU support USB device/host functionality without external components?
Yes - the STM32F411RCT6 integrates a full-speed USB 2.0 OTG controller with an on-chip PHY, supporting both device and host roles without requiring external transceivers. It complies with USB 2.0 specification and supports standard device classes (CDC, HID, MSC) and host enumeration of peripherals like keyboards or mass storage devices.
How many I/O pins are 5 V tolerant and what is their significance?
Up to 49 I/O pins on the STM32F411RCT6 are 5 V tolerant, including all pins in the LQFP64 package except VDD, VSS, NRST, BOOT0, and VCAP. This allows direct interfacing with legacy 5 V logic, sensors, and industrial I/O standards without level-shifters - reducing BOM cost and design complexity in mixed-voltage systems.
What low-power modes are available and what is the lowest achievable current?
The MCU offers Sleep, Stop (with Flash in Stop or Deep power down), and Standby modes. In Stop mode with Flash in Deep power down and slow wakeup, typical current consumption is 9 µA at 25 °C - enabling battery-powered applications with multi-week runtime. RTC remains active in Standby mode consuming only 1.8 µA (no RTC) or 11 µA (at 85 °C).
