Product details
Overview
STM32F401CCU6 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 (16 channels), and 11 communication interfaces including USB OTG FS, SDIO, SPI, I²C, and USART. It targets cost-sensitive embedded control applications requiring real-time performance and low-power operation in industrial sensors and IoT edge nodes.
For engineers reviewing the STM32F401CCU6 datasheet, STM32F401CCU6 pinout, STM32F401CCU6 application, or STM32F401CCU6 equivalent, key selection criteria include its ART Accelerator™ enabling zero-wait-state Flash execution, 5 V-tolerant GPIOs (up to 78 at 42 MHz), dynamic efficiency line with BAM mode, and support for -40 °C to 85 °C industrial temperature range.
Technical Context
The STM32F401CCU6 integrates an Adaptive Real-time Accelerator (ART Accelerator™) that eliminates Flash wait states at 84 MHz, enabling deterministic real-time code execution. Its memory protection unit (MPU) supports secure task isolation in RTOS environments, while the dual-clock domain (HSI/HSI16 + HSE 4–26 MHz) enables flexible low-power clock gating across peripherals.
It implements a multi-AHB bus matrix connecting CPU, DMA, and peripherals, allowing concurrent data transfers without CPU intervention. The 16-stream DMA controller supports burst transfers and FIFO buffering, critical for high-throughput ADC sampling, audio streaming via I²S, and USB endpoint buffering in device/host/OTG configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Cortex-M4 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F411CEU6 | 512 KB Flash, 128 KB SRAM, no SDIO, higher max current (145 µA/MHz) | Better suited for firmware-over-the-air (FOTA) with dual-bank Flash and larger RAM for TLS stacks | Select when needing larger code space and cryptographic acceleration; not drop-in due to different peripheral mapping. |
| STM32G431KBU6 | ARM Cortex-M4, 128 KB Flash, 32 KB SRAM, enhanced analog (2×op-amps, comparator), no USB OTG | Optimized for analog-intensive control loops (e.g., motor gate drivers, power supply regulation) | Prefer for cost-sensitive analog control where USB connectivity is unnecessary and op-amp integration reduces BOM count. |
Compared with STM32F401CCU6, the STM32F411CEU6 offers greater memory headroom for complex protocols but lacks SDIO; the STM32G431KBU6 trades USB and memory for superior analog integration and lower system cost in closed-loop control, making each choice dependent on signal chain architecture rather than raw compute.

FAQ
What is the maximum operating frequency and how is it achieved?
The STM32F401CCU6 achieves 84 MHz maximum CPU frequency using its internal PLL driven by either the 4–26 MHz HSE crystal oscillator or the 16 MHz factory-trimmed HSI RC oscillator. The ART Accelerator™ eliminates Flash wait states at this speed, ensuring deterministic execution. System clocks for peripherals (APB1/APB2) are derived via programmable prescalers, with APB2 supporting up to 84 MHz for timers and I/O.
Does STM32F401CCU6 support USB device mode without external components?
Yes - the STM32F401CCU6 integrates a full-speed USB 2.0 OTG controller with an on-chip PHY, requiring only standard USB DP/DM routing and 1.5 kΩ pull-up resistor on DP for device enumeration. No external transceiver, level shifter, or crystal is needed, reducing BOM count and PCB area for USB-connected peripherals like HID devices or CDC virtual COM ports.
How many ADC channels can be used simultaneously and what is the effective sampling rate?
The single 12-bit ADC supports up to 16 external channels and 3 internal sources (temperature sensor, VREFINT, VBAT). Using DMA and regular sequence mode, it achieves 2.4 MSPS aggregate throughput. With 16-channel scan, maximum sustained sampling rate per channel is ~150 kSPS; interleaved dual-sampling modes are not supported on this variant.
Is the STM32F401CCU6 pin-compatible with other STM32F401 variants?
No - the STM32F401CCU6 (UFQFPN48) is not pin-compatible with LQFP64 (e.g., STM32F401CCT6) or LQFP100 packages. While peripheral functionality overlaps across the F401xB/C family, pin assignments differ significantly between packages. Migration requires PCB redesign; however, software is largely compatible due to identical register maps and HAL driver support.
