Product details
Overview
STM32F401RBT6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, delivering 105 DMIPS at 84 MHz, featuring 256 KB Flash, 64 KB SRAM, and integrated peripherals including 1×12-bit 2.4 MSPS ADC, USB OTG FS, SDIO, and up to 11 communication interfaces. It targets mid-range embedded control in industrial HMI, sensor hubs, and portable medical devices requiring deterministic real-time response and low-power operation.
For engineers reviewing the STM32F401RBT6 datasheet, STM32F401RBT6 pinout, STM32F401RBT6 application, or STM32F401RBT6 equivalent, key selection criteria include Flash/SRAM size, ART Accelerator™-enabled zero-wait-state execution, 5 V-tolerant I/Os, temperature range (–40 °C to 85 °C), and ECOPACK2-compliant LQFP64 packaging for cost-sensitive PCB layouts.
Technical Context
The STM32F401RBT6 implements an Arm Cortex-M4 core with hardware FPU and Adaptive Real-time Accelerator (ART™) enabling deterministic 0-wait-state Flash execution. Its memory subsystem includes 256 KB of dual-bank Flash with ECC support, 64 KB SRAM, and 512 bytes of OTP for secure configuration storage.
Peripherals are organized via a multi-AHB bus matrix supporting concurrent DMA transfers across 16-stream controllers. Clock management integrates four oscillators (HSE 4–26 MHz, HSI 16 MHz, LSE 32.768 kHz, LSI ~37 kHz), dual PLLs (main PLL and audio PLLI2S), and dynamic voltage scaling for power optimization across Run/Stop/Standby modes.

FAQ
What is the maximum operating frequency and associated power supply range?
The STM32F401RBT6 operates at up to 84 MHz across its full 1.7 V to 3.6 V supply range. At 1.8 V, the maximum frequency is 72 MHz; at 3.3 V, it reaches 84 MHz with guaranteed timing margins per DS9716 Rev 11 Section 6.3.1. Voltage scaling is managed automatically by the internal regulator during clock transitions.
Does this MCU support hardware encryption or secure boot features?
No-the STM32F401RBT6 does not integrate a cryptographic processor or dedicated secure boot engine. It lacks AES, DES, or hash accelerators. Secure boot must be implemented in software using the 96-bit unique ID and external secure element or flash-based signature verification with ART Accelerator-optimized routines.
Can the USB interface operate in host mode without external components?
Yes-the USB OTG FS controller includes an integrated PHY and supports both device and host roles. In host mode, it drives standard USB 2.0 full-speed peripherals (e.g., HID keyboards, CDC modems) directly via PA9/PA10, requiring only passive termination resistors and VBUS sensing circuitry per Section 3.26 of the datasheet.
How many I/O pins support external interrupt capability in the LQFP64 package?
All 50 general-purpose I/O pins in the LQFP64 package (PA0–PA15, PB0–PB15, PC13–PC15) support external interrupt/event capability via the EXTI line mapping. Each pin can be individually configured as level- or edge-triggered interrupt source, with up to 23 EXTI lines shared across GPIO ports as defined in Table 8 of DS9716.
