Product details
Overview
STM32F401CCU7 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, one 12-bit 2.4 MSPS ADC, and 11 communication interfaces including USB OTG FS, SPI, I²C, and USART. It targets embedded control in portable medical devices, industrial sensor nodes, and smart home hubs requiring low-power operation and rich peripheral integration.
For engineers reviewing the STM32F401CCU7 datasheet, STM32F401CCU7 pinout, STM32F401CCU7 application, or STM32F401CCU7 equivalent, key selection considerations include its 48-pin UFQFPN package, -40 °C to 85 °C temperature grade, 1.7–3.6 V supply range, ART Accelerator™ for zero-wait-state Flash execution, and 5 V-tolerant GPIOs enabling direct interfacing with legacy logic.
Technical Context
This MCU integrates an Adaptive Real-time Accelerator (ART Accelerator™) that eliminates Flash wait states at 84 MHz, enabling deterministic real-time response. Its memory subsystem includes 256 KB of embedded Flash with error correction, 64 KB SRAM, and 512 bytes of OTP for secure configuration storage.
The clock system supports multiple sources: 4–26 MHz external crystal, 16 MHz factory-trimmed internal RC, and 32 kHz RTC oscillator with calibration. Power management features include Run, Sleep, Stop (with Flash in Deep power-down), and Standby modes-achieving as low as 10 µA typ in Stop mode and 2.4 µA in Standby at 25 °C.

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), higher RAM (128 KB), same 48-pin UFQFPN, but no SDIO and lower max ADC speed (2.4 MSPS → 2.4 MSPS unchanged) | Preferred where larger code footprint required (e.g., full TCP/IP stack), but SDIO not needed | Select if firmware size exceeds 256 KB or additional SRAM is critical for buffering; otherwise, STM32F401CCU7 offers better cost/performance balance |
| STM32F072CBU6 | Cortex-M0 core, 128 KB Flash, 16 KB SRAM, no FPU, no ART Accelerator, 48 MHz max clock | Suitable for simpler control tasks (e.g., LED lighting, basic motor control) without DSP or USB host needs | Choose only when application requires no floating-point math, USB OTG, or high-speed ADC - significantly lower performance and peripheral count |
Compared with STM32F411CEU6, the STM32F401CCU7 trades Flash/RAM capacity for lower unit cost and identical ADC/USB capabilities; versus STM32F072CBU6, it delivers 2.2× higher DMIPS, FPU, and full USB OTG functionality - making it optimal for mid-tier connected edge devices demanding balanced performance and integration.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating?
The STM32F401CCU7 operates at up to 84 MHz with an Arm Cortex-M4 core featuring FPU and ART Accelerator™, achieving 105 DMIPS (Dhrystone 2.1). This performance level is sustained with zero-wait-state execution from Flash memory, verified under 1.7–3.6 V supply and -40 °C to +85 °C ambient conditions per DS9716 Rev 11.
Does this MCU support USB device, host, and OTG functionality simultaneously?
Yes - the integrated USB 2.0 full-speed OTG controller supports device, host, and OTG roles using a single physical interface. It includes an on-chip PHY, eliminating external transceivers. Role switching is managed in firmware via the USB_OTG_FS peripheral registers, and has been validated in ST's USB Device Library v2.2.1 and Host Library v2.2.1.
How many I/O pins are available in the UFQFPN48 package, and are they 5 V tolerant?
The STM32F401CCU7 in UFQFPN48 provides 36 general-purpose I/O pins (PA0–PA15, PB0–PB15, PC0–PC15, PD0–PD2), all of which are 5 V tolerant across the full 1.7–3.6 V VDD range. This tolerance is confirmed in Section 6.3.16 ("I/O port characteristics") of DS9716 Rev 11, allowing direct connection to 5 V logic without external level shifters.
What low-power modes are supported, and what is the lowest achievable current draw?
Five low-power modes are supported: Sleep, Stop (with Flash in Stop or Deep power-down), and Standby. The lowest current is 2.4 µA in Standby mode at 25 °C and 1.7 V (without RTC), and 10 µA typ in Stop mode with Flash in Deep power-down at 25 °C - both measured with VBAT disconnected and all clocks gated, per Table 29 and Table 27 in DS9716 Rev 11.
