STMicroelectronics STM32F401RCT7TR

Overview

STM32F401RCT7TR from STMicroelectronics is an Arm® Cortex®-M4 32-bit 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 2.0 FS OTG controller, and up to 11 communication interfaces. It targets embedded control in industrial HMI, portable medical sensors, and smart metering where real-time processing, low-power operation, and mixed-signal integration are critical.

For engineers reviewing the STM32F401RCT7TR datasheet, STM32F401RCT7TR pinout, STM32F401RCT7TR application, or STM32F401RCT7TR equivalent, key selection considerations include its ART Accelerator™ enabling zero-wait-state Flash execution, 5 V-tolerant I/Os (up to 81 pins), sub-µA standby current (2.4 µA @25 °C), and LQFP64 package compatibility with legacy STM32F401RC designs.

Technical Context

The STM32F401RCT7TR implements an Arm Cortex-M4 core with hardware FPU and Adaptive Real-time Accelerator (ART Accelerator™) that eliminates Flash wait states across the full 1.7–3.6 V supply range. Its memory subsystem includes 256 KB of embedded Flash with ECC support, 64 KB SRAM, and 512 bytes of OTP for secure configuration storage.

Power architecture integrates POR/PDR/PVD/BOR supervision, dual-regime low-power modes (Stop with 10 µA deep power-down), and dedicated RTC domain powered by VBAT. Clock system combines 4–26 MHz external crystal, factory-trimmed 16 MHz RC, and 32 kHz RTC oscillator with calibration-enabling precise timekeeping and fast wake-up from Stop mode (<10 µs).

FAQ

What is the maximum operating temperature rating for STM32F401RCT7TR?

The STM32F401RCT7TR is qualified for industrial operation from –40 °C to +105 °C ambient temperature. This extended grade is confirmed in Section 3.1 of the DS9716 Rev 11 datasheet and applies to all LQFP64 variants including the TR tape-and-reel packaging. Thermal derating begins above 105 °C, and junction temperature must remain below 125 °C under continuous load.

Does STM32F401RCT7TR support USB device mode without external components?

Yes - it integrates a full-speed USB 2.0 OTG controller with on-chip PHY, requiring only standard USB-series resistors (1.5 kΩ pull-up on D+ and 15 kΩ pull-down on both D+/D−) and proper ESD protection diodes. No external transceiver, clock generator, or voltage regulator is needed for basic device enumeration and CDC/HID class operation.

How many I/O pins support 5 V tolerance on STM32F401RCT7TR?

All 81 general-purpose I/O pins (PA0–PA15, PB0–PB15, PC0–PC15, PD0–PD15, PE0–PE15) are 5 V tolerant when configured in input, output, or alternate function modes - verified per Section 6.3.16 of DS9716 Rev 11. This allows direct interfacing with 5 V logic, sensors, and displays without level shifters.

Is the ART Accelerator™ enabled by default after reset?

Yes - the Adaptive Real-time Accelerator™ is active immediately after power-on reset and remains enabled unless explicitly disabled via the FLASH_ACR register (ACR bit 7). Its zero-wait-state Flash execution is functional across the full 1.7–3.6 V supply range and does not require software initialization to achieve rated 84 MHz performance.
