STM32F427IIH7 - 180MHz Cortex-M4 MCU | STMicroelectronics
部品番号: STM32F427IIH7 ✓ 生産中STM32F427IIH7 概要
A microcontroller is a programmable semiconductor integrated circuit that combines a processor core, memory, and peripherals on one device. It forms the central control element of an embedded system, operating within the hierarchy of embedded processor, microcontroller, and integrated circuit. Unlike a general-purpose computer processor, a microcontroller is designed around compact hardware, real-time execution, low-power operation, and direct access to sensors, communications interfaces, communications peripherals, and actuators.
The STM32F427IIH7's principal characteristics include its 180 MHz maximum core frequency, 2 MB flash program memory, 32-bit processing architecture, and 176-UFBGA package. The single-precision FPU accelerates floating-point calculations, while the Cortex-M4 DSP instruction set improves the execution of common filtering and signal-processing operations. These capabilities reduce the need for an external accelerator when an application includes digital control, data acquisition, communications, or embedded math.
The STM32F427 and STM32F429 families share a high-performance Arm Cortex-M4 architecture and are documented in the manufacturer datasheet. Memory-space planning is especially important because firmware, boot code, application code, and data-storage requirements compete for internal resources. Designers should also account for bank arrangement, boot configuration, clock-tree setup, peripheral pin multiplexing, and the electrical requirements of each selected I/O when laying out a production PCB.
Typical application domains include industrial automation and factory control, communications equipment, high-end audio and digital signal processing, network-connected embedded systems, and compact control platforms. The combination of a 180 MHz core, DSP instructions, FPU, and 2 MB flash provides a practical balance of processing headroom and embedded integration for designs that need more control capability than a basic microcontroller provides.
A critical design consideration is the dense 176-UFBGA footprint. The manufacturer pin description, package drawing, and board layout guidance should be used directly for ball assignment, exposed-pad connection, power distribution, and assembly design. This page combines device identification, verified technical data, same-family drop-in options, and practical design guidance to support component selection and PCB planning.

主な用途
STM32F427IIH7 の用途: 6 件s: Industrial Automation and Factory Control, Industrial and Building Networking, High-End Audio and Signal Processing, Data Acquisition and Test Equipment, Smart IoT and Connected Equipment, Secure Communications and Network Appliances.
Industrial Automation and Factory Control
The STM32F427IIH7 fits industrial automation controllers that need deterministic real-time execution alongside communication and data-processing functions. Its 180 MHz Arm Cortex-M4 core provides headroom for control loops, state-machine logic, and supervisory tasks, while the single-precision FPU and DSP instructions accelerate arithmetic-heavy operations without requiring a separate accelerator. The 2 MB flash capacity supports a larger application code footprint and integrated protocol stacks. Use the MCU as the central controller for sensor acquisition, actuator supervision, and communications management, while validating the exact temperature grade and peripheral requirements for the installed enclosure. The 176-UFBGA package also demands careful power, grounding, and assembly planning in industrial boards exposed to vibration and thermal cycling.
おすすめ
Industrial and Building Networking
The STM32F427IIH7 is suitable for embedded network equipment requiring a high-performance control processor and flexible communications architecture. Its 180 MHz Cortex-M4 core can process protocol stacks, maintain control tasks, and support real-time status handling, while the DSP instruction set benefits packet processing and signal-related workloads. The 2 MB flash allows more application code and firmware to be consolidated on the MCU, reducing the need for external memory in compact designs. Designers can pair it with dedicated interface silicon for Ethernet, USB, or isolated serial links when the selected board requires standardized physical-layer connectivity. Production qualification should confirm the enabled communications peripherals, I/O mapping, clock requirements, and thermal performance before the design is released for volume deployment.
おすすめ
High-End Audio and Signal Processing
The STM32F427IIH7 can serve as the real-time processor in high-end audio equipment, active speakers, digital filter platforms, and other signal-processing products. Its Cortex-M4 core operates up to 180 MHz and includes a single-precision FPU plus DSP instructions, providing a practical architecture for filtering, mixing, equalization, and control algorithms. The 2 MB flash memory supports substantial firmware and lookup data, including DSP routines and communication firmware. In a typical design, the MCU receives digital audio or sensor data through an appropriate peripheral, executes the signal chain, and manages configuration interfaces or status indicators. Performance must be validated under the intended data rate and memory-access pattern because the complete audio system includes converters, clocks, DMA movement, and analog output stages beyond the processor itself.
おすすめ
Data Acquisition and Test Equipment
The STM32F427IIH7 is well suited to compact data-acquisition and test-instrument controllers that combine fast sampling control with communication and configuration functions. The 180 MHz Cortex-M4 core supports deterministic acquisition sequencing, digital filtering, calibration calculations, and control of test stimuli, while the FPU improves numeric workload efficiency. Its 2 MB flash permits integrated firmware for acquisition, filtering, analysis, and user-interface communication. A practical design can use the MCU to configure converters, move sampled data by DMA, execute digital processing, and publish results over USB or a network interface. Designers should allocate processing time between acquisition and communication carefully, validate interrupt latency, and confirm the exact analog and communication peripheral capabilities in the manufacturer datasheet before finalizing channel count and throughput.
おすすめ
Smart IoT and Connected Equipment
The STM32F427IIH7 can serve as the application processor in connected IoT equipment where local control must continue even when higher-level network services are unavailable. Its 180 MHz Cortex-M4 core provides enough performance for sensor fusion, local decision logic, protocol handling, and user-interface updates, while 2 MB flash supports a consolidated firmware image. In a smart-device design, the MCU manages local sensors and actuators, buffers data, controls status indicators, and coordinates a communications coprocessor or network interface. This arrangement keeps time-critical behavior close to the hardware and avoids burdening a low-power wireless device with complex control tasks. Product developers should confirm the required peripheral mix, boot method, memory map, and low-power behavior, because the 176-UFBGA package also adds land-pattern and assembly complexity compared with a leaded MCU.
おすすめ
Secure Communications and Network Appliances
The STM32F427IIH7 is applicable to communications appliances and protocol-conversion equipment that require a fast 32-bit processor, local memory, and extensive integration. The Cortex-M4 core at up to 180 MHz can manage framing, routing tables, monitoring, and device-control logic, while the DSP instruction set supports efficient manipulation of coded or converted data. The 2 MB flash capacity is suitable for firmware and configuration components that must be held locally. A typical architecture places the MCU beside a dedicated Ethernet or USB controller, using DMA and interrupt-driven communication while the processor handles management, diagnostics, and protocol translation. Production evaluation must verify which security peripherals and acceleration functions are populated on the exact ordering variant, as well as the electrical limits, boot configuration, and firmware update mechanism required by the target security boundary.

主な差別化要因
- Direct H7-grade ordering option in the 176-UFBGA STM32F4 family （vs STM32F427IIH6)
- F427-family feature set in the same high-pin-count package （vs STM32F429IIH7)
- High-density integration without reducing core processing frequency （vs STM32F427IIG6)
設計ノート
Treat the 176-UFBGA layout as a high-density BGA design rather than adapting a generic QFN land pattern. Assign signals using the manufacturer pin-description table, preserve the documented ball coordinates, and follow the recommended via, mask, and pad geometry. The 10 mm by 10 mm package is too fine-pitched for an improvised footprint, so use the STMicroelectronics package drawing and PCB library dimensions as the controlling mechanical references.
Design the power distribution network around the exact 2.5 V or 3.3 V operating requirements in the STM32F427xx and STM32F429xx datasheet. Place the required decoupling capacitors at the associated supply balls with short, low-inductance paths, and provide a clean return connection for every supply and ground ball. Do not infer capacitor values or placement from generic STM32 guidance because the exact power architecture and device variant must be checked in the manufacturer documentation.
Separate sensitive analog, clock, and communications routes from fast digital and switching-node traces where the board stack-up permits. Route the clock input and other high-value analog connections away from noisy power converters and digital return currents, and follow the datasheet's external-component recommendations. Firmware timing margins are lost when layout adds crosstalk, ground bounce, or reference-voltage disturbance, so validate the completed board with representative analog and communication workloads.
Do not approve an alternate STM32F4 part from the suffix alone. Confirm the exact package, ball map, operating voltage, temperature grade, memory configuration, peripheral population, boot configuration, and firmware expectations for every proposed substitute. The STM32F427 and STM32F429 families share a 180 MHz Cortex-M4 platform, but that common core does not guarantee identical peripheral behavior or complete software compatibility.
