Product details
Overview
STM32F401RCT6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating up to 84 MHz, featuring 256 KB Flash, 64 KB SRAM, one 12-bit 2.4 MSPS ADC, and 11 communication interfaces including USB OTG FS, SPI, I²C, and USART. It targets embedded control in industrial sensors, portable medical devices, and smart home hubs requiring deterministic real-time response and low-power operation.
For engineers reviewing the STM32F401RCT6 datasheet, STM32F401RCT6 pinout, STM32F401RCT6 application, or STM32F401RCT6 equivalent, key selection criteria include Flash/SRAM size, 84 MHz max CPU frequency with ART Accelerator™, 105 DMIPS performance, 5 V-tolerant GPIOs, and integrated USB 2.0 full-speed OTG controller with on-chip PHY.
Technical Context
The device integrates an Adaptive Real-time Accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash at 84 MHz, alongside 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/32 kHz RC sources with calibration, and dedicated audio PLL (PLLI2S) for I²S audio timing.
Power architecture supports multiple low-power modes: Stop mode with 10 µA (deep power-down), Standby at 2.4 µA (no RTC), and Run mode at 128 µA/MHz. Peripheral integration includes 16-stream DMA, nested vectored interrupt controller (NVIC), and SWD/JTAG debug with Embedded Trace Macrocell™.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F411CEU6 | Higher Flash (512 KB), same 84 MHz Cortex-M4, but no USB OTG FS PHY - requires external transceiver. | Better suited for code-heavy applications needing larger firmware space; unsuitable where USB device/host plug-and-play is mandatory. | Select when Flash headroom > USB integration; verify external PHY BOM impact and layout complexity. |
| STM32F072RBT6 | Cortex-M0 core, 48 MHz, 128 KB Flash, USB 2.0 FS (with PHY), lower DMIPS (38.4), no FPU or ART Accelerator. | Targeted at cost-sensitive, less computationally intensive tasks like simple HID devices or basic motor control. | Choose for budget-constrained designs where floating-point math and high-speed ADC are unnecessary. |
Compared with STM32F401RCT6, the STM32F411CEU6 trades integrated USB PHY for doubled Flash capacity-ideal for feature-rich firmware-but the STM32F072RBT6 offers lower cost and power at the expense of real-time performance and analog precision, making it appropriate only for simpler control loops.

FAQ
What is the maximum operating temperature for STM32F401RCT6?
The STM32F401RCT6 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 DS9716 Rev 11 datasheet and applies to the LQFP64 package variant under specified voltage and derating conditions.
Does STM32F401RCT6 support USB device mode without external components?
Yes. The part integrates a full-speed USB 2.0 OTG controller with on-chip PHY, requiring only standard USB connector wiring and 1.5 kΩ pull-up resistor on D+ for device enumeration. No external transceiver or level shifter is needed for basic USB device functionality.
How many ADC channels are available, and what is their maximum sampling rate?
The device features one 12-bit ADC with up to 16 external input channels and a maximum sampling rate of 2.4 MSPS. This performance is achievable at fADC = 36 MHz, as verified in Table 66 and Table 69 of the DS9716 datasheet under VDD = 3.3 V conditions.
Is the STM32F401RCT6 pin-compatible with other STM32F401 variants?
No - STM32F401RCT6 uses the LQFP64 package, while variants like STM32F401VET6 (LQFP100) and STM32F401CBU6 (UFQFPN48) have different pin counts and layouts. Pin compatibility exists only within the same package family (e.g., STM32F401RCT6 and STM32F401RBT6 share LQFP64 footprint but differ in Flash size).
