Product details
Overview
STM32F411RCT7TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 512 KB Flash, 128 KB SRAM, USB OTG FS controller, and 100 MHz max CPU frequency. It integrates 1×12-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.
For engineers reviewing the STM32F411RCT7TR datasheet, STM32F411RCT7TR pinout, STM32F411RCT7TR application, or STM32F411RCT7TR equivalent, key selection factors include its 100 MHz ART-accelerated flash execution, 9 µA Stop mode power consumption (Deep Power Down), 77 5 V-tolerant I/Os, and integrated USB OTG FS PHY for embedded host/device connectivity.
Technical Context
The device implements an adaptive real-time accelerator (ART Accelerator) enabling zero-wait-state execution from Flash at 100 MHz, paired with a memory protection unit (MPU) for secure task isolation. Its clock system includes dual oscillators (4–26 MHz HSE and 32 kHz LSE), internal 16 MHz HSI and 32 kHz LSI with calibration, and dual PLLs (main PLL + audio PLLI2S) supporting flexible peripheral clock routing.
Power architecture supports dynamic efficiency line operation across 1.7–3.6 V supply, with four low-power modes: Run (100 µA/MHz), Stop (9–65 µA), Standby (1.8–11 µA), and VBAT RTC mode (1 µA). Batch Acquisition Mode (BAM) enables ultra-low-power sensor data capture while keeping CPU asleep.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F401RET6 | Same Cortex-M4 core but 512 KB Flash, 96 KB SRAM, no USB OTG FS PHY, lower peripheral count (2×I²C, 2×SPI) | Lacks integrated USB transceiver and audio PLL-requires external PHY for USB host functionality | Select when USB is not required and cost-sensitive BOM optimization is critical |
| STM32F412ZGT6 | Higher integration: 1 MB Flash, 256 KB SRAM, USB OTG HS/FS, Chrom-ART accelerator, AES crypto, no BAM | Includes hardware crypto and higher-resolution graphics acceleration-over-spec for pure sensor/motor control | Choose when future-proofing for secure OTA updates or display subsystem expansion is needed |
Compared with STM32F401RET6, the STM32F411RCT7TR adds USB OTG FS PHY and BAM for ultra-low-power sensor acquisition; versus STM32F412ZGT6, it trades crypto and larger memory for lower cost and optimized power efficiency in resource-constrained edge nodes.

FAQ
What is the maximum operating temperature range for STM32F411RCT7TR?
The STM32F411RCT7TR is rated for industrial temperature range: –40°C to +105°C ambient. This is confirmed in DS10314 Rev 8, Section 6.3.1 (General operating conditions), and applies to all package variants including the UFQFPN48. The extended range supports deployment in enclosed industrial enclosures and automotive under-hood auxiliary modules.
Does STM32F411RCT7TR support external memory interfaces like SDRAM or NOR Flash?
No, the STM32F411RCT7TR does not integrate FSMC (Flexible Static Memory Controller) or FMC (Flexible Memory Controller). Unlike higher-end F4 variants (e.g., STM32F429), it lacks dedicated address/data bus pins and memory mapping for external parallel memories. Designers requiring external storage must use SPI NOR/NAND or SDIO eMMC instead.
Can the USB OTG FS interface operate in host-only mode without device capability?
Yes-the USB OTG FS controller supports Host-only, Device-only, and On-The-Go modes via software configuration. In Host-only mode, PA9/PA10 function as DP/DM transceiver lines, while PA11 (ID) is pulled high internally and PA12 (VBUS) monitors power presence. No hardware modification is needed to lock into host mode.
Is the 96-bit unique ID accessible via standard debug interfaces?
Yes, the 96-bit unique device identifier is readable via SWD/JTAG through the DBGMCU_IDCODE register (address 0xE0042000) and also accessible in firmware via system memory read at 0x1FFF7A10. It is factory-programmed, unalterable, and usable for secure boot key binding or license enforcement without external secure elements.
