STM32F401CCU6 - 84MHz Cortex-M4 MCU | STMicroelectronics
N.º de pieza: STM32F401CCU6 ✓ ActivoSTM32F401CCU6 Descripción general
An Arm Cortex-M4 microcontroller is a member of the microcontroller hierarchy within embedded semiconductors. Its reduced-instruction-set architecture executes interrupt-driven control tasks, while the Cortex-M4 core adds digital signal-processing instructions and single-precision floating-point hardware. STM32F401 devices belong to STMicroelectronics' Dynamic Efficiency Line, positioning them between general-purpose control and higher-performance Cortex-M4 products.
Key features include an 84 MHz maximum CPU frequency, 105 DMIPS performance, 256 KB of Flash, and 64 KB of SRAM. The single ADC supports analog measurement, while the 11 timers support timing, input capture, output compare, PWM generation, and motor-control functions. Eleven communication interfaces support industrial, consumer, and communications-oriented embedded products without requiring a separate host processor.
The STM32F401CCU6 uses an Arm Cortex-M4 processor with DSP and FPU capability. The ART Accelerator improves Flash-memory access behavior, while the integrated FPU accelerates suitable single-precision arithmetic. Program execution, bootloader operation, debugging, and peripheral configuration are handled through the STM32 embedded ecosystem and supported development tools. Exact peripheral assignments and alternate-function details remain product-specific and must be checked against the manufacturer documentation for the selected board.
Typical uses include connected sensor equipment, industrial control modules, compact consumer devices, communication equipment, and real-time embedded platforms. The 256 KB Flash capacity is suitable for moderate application code, while the 84 MHz processing rate supports responsive control loops, protocol handling, and signal processing. The 48-pin package reduces board area when compared with larger leaded microcontroller packages.
Designers should verify every assigned pin against the UFQFPN48 land pattern, exposed-pad requirements, and the device pinout. The 1.7 V to 3.6 V operating range must also be reconciled with the selected regulator tolerance. Firmware should include appropriate startup configuration, clock initialization, and pin-level checks before production release.
This product page combines verified manufacturer and distributor data, density-specific drop-in alternatives, application guidance, and design considerations. It is intended to accelerate component selection while preserving the need for final schematic, firmware, and qualification review against the official STM32F401 documentation.

Aplicaciones típicas
STM32F401CCU6 es adecuado para 6 aplicacións: Industrial Sensor Controller, Connected IoT Sensor Node, Compact Communications Module, USB-Consumer Accessory, Precision Control Module, Real-Time Data Acquisition.
Industrial Sensor Controller
The STM32F401CCU6 fits compact sensor-control equipment that must acquire analog measurements and run real-time filtering. Its 84 MHz Cortex-M4 core provides 105 DMIPS, while the DSP instructions and integrated FPU can accelerate suitable signal-processing workloads without adding a separate processor. The device includes one ADC, 11 timers, and 11 communication interfaces, allowing a controller to sample inputs, drive timing or PWM functions, and communicate with remote sensors. The 256 KB Flash and 64 KB SRAM support moderate application code and data buffering. Its 48-pin 7 x 7 mm UFQFPN package also reduces board area, although the exact ADC accuracy and channel mapping must be verified against the manufacturer datasheet.
Recomendado
Connected IoT Sensor Node
The STM32F401CCU6 can serve as the local control processor in a connected sensor node where 256 KB of Flash, 64 KB of SRAM, and an 84 MHz Cortex-M4 core are sufficient. Its 11 communication interfaces provide options for serial, bus, or other supported peripheral connectivity, while the 11 timers support periodic sampling and low-power wake-up sequencing. The 1.7 V to 3.6 V supply range can accommodate compact sensor-node power designs. Firmware should enable only the required peripherals to conserve energy, and the final radio interface, antenna, regulatory approvals, and deep-sleep performance remain separate design requirements that are not established by the supplied component data.
Recomendado
Compact Communications Module
The STM32F401CCU6 is appropriate for a compact communications module that needs protocol processing, event handling, and deterministic timer support in one device. Its 105 DMIPS Cortex-M4 performance provides more headroom than an 8-bit MCU, while the 11 communication interfaces can reduce the need for external interface devices. The 256 KB Flash and 64 KB SRAM are adequate for many protocol stacks, bootloader functions, and configuration data. Engineers should confirm that the required UART, SPI, I2C, USB, or other interface instance is present and mapped to the intended pins. If a separate Ethernet PHY is used, its digital interface and clocking requirements must be checked against the selected UFQFPN48 pin assignments.
Recomendado
USB-Consumer Accessory
The STM32F401CCU6 can control a compact USB-oriented consumer accessory when its supported USB or serial interface satisfies the product requirements. The 84 MHz Cortex-M4 core can manage protocol software, control logic, status indication, and user input, while 64 KB of SRAM provides working space for moderate data buffering. Its small 48-pin UFQFPN package is useful for space-constrained enclosures, and the 1.7 V to 3.6 V supply range supports common low-voltage power trees. A production design still needs exact USB data-pin routing, connector protection, bus-power budgeting, enumeration testing, and validation of the selected package and exposed-pad layout before release.
Recomendado
Precision Control Module
The STM32F401CCU6 is suited to precision control modules that combine timing, PWM, and moderate floating-point computation. Its 11 timers can support multiple time-critical functions, and the Cortex-M4 FPU can improve handling of fractional control calculations when the application benefits from single-precision hardware arithmetic. The 256 KB Flash and 64 KB SRAM provide room for control code, calibration constants, and operating data. The 1.7 V to 3.6 V operating range gives designers flexibility in low-voltage power architectures. Final selection should account for ADC resolution, timer channel availability, pin alternate functions, control-loop latency, and the absence of verified isolation or functional-safety certification in the supplied data.
Recomendado
Real-Time Data Acquisition
The STM32F401CCU6 can act as a real-time acquisition controller for compact systems that need MCU-based control alongside external high-speed conversion. Its 84 MHz Cortex-M4 core and 105 DMIPS rating support responsive data handling, while the single internal ADC and 11 timers provide measurement and trigger functions. The 256 KB Flash can hold acquisition firmware, and 64 KB of SRAM can buffer intermediate results when the data rate permits. For higher-bandwidth analog signals, the AD9221AR provides a suitable external ADC class, but clock sources, data-bus routing, scaling, and input bandwidth must be designed together. The internal ADC should not be assumed to meet the same bandwidth or accuracy as an external converter.

Notas de diseño
Use the official STM32F401 UFQFPN48 land pattern and verify the exposed-pad connection, thermal-pad dimensions, and paste mask before PCB release. Keep the 1.7 V to 3.6 V supply and ground connections short, and place local bypass capacitors immediately beside their associated supply pins. The supplied data confirms the 7 x 7 mm package but does not provide recommended capacitor values or land-pattern dimensions, so those values must come directly from the manufacturer package drawing and application guidance.
Do not treat every STM32F401 density code as an automatic drop-in substitute. The CC, CD, and CE ordering codes can represent different Flash-density options, and replacing a 256 KB CC device with the CB option may leave insufficient space for application code or the bootloader. Before substitution, compare the memory map, firmware image, boot-loader requirements, option bytes, temperature grade, exposed pad, and all board-assigned pin functions. This prevents a nominal package match from becoming a firmware or boot failure.
Design the regulator for the full 1.7 V to 3.6 V device range and verify startup, current limit, ripple, and brownout behavior under the selected load. The Cortex-M4 core can operate up to 84 MHz, but maximum-clock power behavior and exact current limits were not included in the supplied data. Use the manufacturer power-consumption table and application notes for operating-mode currents, and validate the power tree with the final peripherals, clock configuration, temperature range, and board-level voltage-drop assumptions.
Assign communication interfaces, timers, ADC inputs, and debug signals before finalizing the UFQFPN48 footprint because alternate functions can constrain otherwise interchangeable pins. Route high-speed or sensitive signals according to the actual peripheral requirements, maintain a continuous ground reference, and keep switching or RF circuitry away from the analog inputs. The source material does not identify every alternate-function mapping, so the device pin table and reference manual RM0368 must be treated as the authoritative sources for board-level routing decisions.
Información de cumplimiento
The supplied verified data does not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable because STM32F401CCU6 is not identified as an automotive-qualified ordering variant. Compliance declarations must be confirmed on the current manufacturer product page or material declaration before procurement.
