STMicroelectronics STM32F401RCT6TR

Overview

STM32F401RCT6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating up to 84 MHz, featuring 256 KB Flash, 64 KB SRAM, and integrated USB 2.0 FS OTG controller with on-chip PHY. It includes one 12-bit 2.4 MSPS ADC (16 channels), 11 communication interfaces (3×I²C, 3×USART, 4×SPI), and supports -40 °C to 85 °C industrial temperature range. Used in motor control gate drivers requiring real-time PWM timing and analog feedback.

For engineers reviewing the STM32F401RCT6TR datasheet, STM32F401RCT6TR pinout, STM32F401RCT6TR application, or STM32F401RCT6TR equivalent, key selection criteria include ART Accelerator™-enabled zero-wait-state Flash execution, 5 V-tolerant GPIOs (up to 78 at 42 MHz), low-power Stop mode current (10 µA typ), and SDIO interface for embedded storage expansion.

Technical Context

The device implements an Adaptive Real-time Accelerator (ART Accelerator™) that eliminates Flash wait states at 84 MHz, enabling deterministic 105 DMIPS performance. Its memory subsystem integrates 256 KB of dual-bank Flash with ECC support, 64 KB SRAM, and 512 bytes of OTP for secure boot configuration.

Clock architecture includes four oscillators: 4–26 MHz external crystal, 16 MHz factory-trimmed HSI, 32 kHz LSE for RTC calendar, and 32 kHz LSI for watchdog timing - all managed by a programmable PLL supporting USB, audio (PLLI2S), and system clock derivation.

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32F401RCT6TR achieves 84 MHz maximum system clock using its main PLL driven by either the 4–26 MHz external crystal or the internal 16 MHz HSI oscillator. The ART Accelerator™ enables zero-wait-state execution from Flash memory at this frequency, delivering consistent 105 DMIPS performance without cache-related timing jitter - critical for deterministic control loops.

Does this MCU support USB device and host functionality simultaneously?

No. The USB 2.0 full-speed peripheral supports device, host, or OTG operation - but only one mode at a time, selected at runtime via software configuration of the USB_OTG_FS_GCCFG register. OTG mode requires external ID pin detection and VBUS sensing circuitry to switch roles dynamically during cable attachment.

How many ADC channels can be used concurrently and at what resolution?

The single 12-bit ADC supports up to 16 external input channels (via PA0–PA7, PB0–PB1, PC0–PC5, etc.) with simultaneous sampling possible only in injected mode using hardware triggers. Full 12-bit resolution is maintained at 2.4 MSPS sampling rate; oversampling can extend effective resolution to 16 bits at reduced throughput.

What packaging and RoHS compliance status does STM32F401RCT6TR have?

It uses an LQFP64 (10 × 10 mm, 0.5 mm pitch) package with ECOPACK2 compliance - meaning lead-free, halogen-free, and fully RoHS 2011/65/EU and REACH SVHC-compliant. The "TR" suffix indicates tape-and-reel packaging for automated SMT assembly, with moisture sensitivity level (MSL) 3 per J-STD-020.
