Product details
Overview
STM32F401CCU6TR 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 (16 channels), USB 2.0 FS OTG controller with on-chip PHY, and 11 communication interfaces including 3×I²C, 3×USART, and 4×SPI. 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 STM32F401CCU6TR datasheet, STM32F401CCU6TR pinout, STM32F401CCU6TR application, or STM32F401CCU6TR equivalent, key selection criteria include ART Accelerator™-enabled zero-wait-state Flash execution, 105 DMIPS performance at 84 MHz, VBAT-backed RTC with subsecond accuracy, and 5 V-tolerant I/Os supporting mixed-voltage system interfacing.
Technical Context
The device integrates an Adaptive Real-Time Accelerator (ART Accelerator™) that eliminates Flash wait states at 84 MHz, enabling deterministic code execution critical for motor control and audio processing. Its memory subsystem includes 256 KB of dual-bank Flash with hardware ECC, 64 KB SRAM, and 512 bytes of OTP for secure boot configuration.
Power architecture supports multiple low-power modes: Stop mode with 10 µA (deep power-down) and Standby mode at 2.4 µA (no RTC), managed by integrated POR/PDR/PVD/BOR and a 32 kHz calibrated LSE oscillator for precise RTC timing independent of main supply.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F401CBU6 | Same core, Flash (128 KB), RAM (64 KB), and UFQFPN48 package; lacks USB OTG PHY - requires external transceiver | Suitable for cost-sensitive designs where USB is not required or implemented externally | Select when USB device functionality is unnecessary and BOM cost reduction is prioritized over integration |
| STM32F411CEU6 | Higher Flash (512 KB), same RAM (128 KB), identical UFQFPN48 package; adds 2× more DMA streams and faster ADC (2.4 MSPS → 3.6 MSPS) | Better suited for complex firmware with multiple concurrent protocols (e.g., USB + SDIO + BLE coexistence) | Choose when future firmware expansion, larger OTA update images, or higher ADC throughput are required |
Compared with STM32F401CBU6, the STM32F401CCU6TR provides integrated USB PHY and double Flash capacity for feature-rich firmware; versus STM32F411CEU6, it trades Flash size and ADC speed for lower unit cost and proven qualification in high-volume consumer applications.

FAQ
What is the maximum operating frequency and corresponding performance metric?
The STM32F401CCU6TR operates at up to 84 MHz with an integer performance of 105 DMIPS (Dhrystone 2.1), measured at 1.25 DMIPS/MHz. This rating assumes ART Accelerator™ enabled and zero-wait-state Flash execution - verified per ST's DS9716 Rev 11 test conditions at 25 °C and 3.3 V supply.
Does this MCU support hardware encryption or secure boot features?
No. The STM32F401CCU6TR does not integrate hardware cryptographic accelerators (AES, SHA, PKA) or tamper-detect circuitry. Secure boot relies on software-implemented signature verification in user Flash; the 512-byte OTP memory may store public keys but lacks write-protection fuses or secure ROM bootloader.
Can the USB interface operate in host mode without external components?
No. While the MCU includes a USB 2.0 Full-Speed OTG controller with on-chip PHY, host mode requires external VBUS sensing, overcurrent protection, and 5 V power switching circuitry. Device mode functions fully with only the internal PHY and standard USB termination resistors.
What is the guaranteed minimum operating temperature range for industrial use?
The STM32F401CCU6TR is qualified for industrial operation from –40 °C to +85 °C ambient temperature, as specified in Table 14 (General Operating Conditions) of DS9716 Rev 11. Extended temperature variants (up to +105 °C) exist but require different part numbers (e.g., STM32F401CCU6TR with suffix '-X').
