STM32F469AIH6 - 180MHz Cortex-M4 MCU, 2MB Flash | STMicroelectronics
部品番号: STM32F469AIH6 ✓ 生産中STM32F469AIH6 概要
A microcontroller is a programmable system-on-chip that integrates a CPU core, nonvolatile program memory, working memory, and interfaces such as serial communications, timers, analog inputs, and general-purpose I/O. Within the product hierarchy, the STM32F469AIH6 is an Arm Cortex-M4 MCU, part of the STM32 family, and ultimately belongs to the broader embedded-processor and semiconductor categories. Its 32-bit architecture supports efficient control, communications, signal-processing, and human-interface applications.
The Cortex-M4 core includes a single-precision FPU for accelerated floating-point calculations and a complete DSP instruction set. These features distinguish the device from basic Cortex-M-class controllers when an application requires greater arithmetic throughput, efficient digital filtering, audio processing, or control-loop performance. The 2 MB embedded Flash provides substantially more program space than entry-level STM32 devices, allowing larger firmware images, protocol stacks, and application logic to be consolidated on one MCU.
The STM32F469AIH6 also provides an STM32F4-series combination of high processing speed, sophisticated peripherals, and low-power operating modes. Its 169-UFBGA land pattern is intended for compact, multilayer PCB designs, but its 0.4 mm-class ball pitch requires careful escape routing and manufacturing capability. The official STM32F469AE datasheet applies to the STM32F469xx device family, including the STM32F469AIH6 ordering variant.
Typical uses include industrial automation, connected industrial equipment, audio and digital signal processing, industrial networking, motor and motion control, human-machine interfaces, and embedded gateways. In each case, the 180 MHz Cortex-M4 execution rate and DSP/FPU support help consolidate real-time processing that might otherwise require a separate processor.
Designers should assign all 169 balls according to the official pin-definition and package tables rather than relying on generic BGA conventions. Power, decoupling, clock, reset, boot, and high-speed interface layouts must follow STMicroelectronics guidance, while exposed thermal and assembly constraints require qualification through the selected PCB process. Firmware migration should also be reviewed against the exact STM32F469xx device revision and ST peripheral library configuration.
This product page combines the official family documentation with verified distributor references, same-package family alternatives, application guidance, comparison parameters, and practical PCB considerations. It is intended to help engineers evaluate processing capacity, memory, package complexity, lifecycle suitability, and firmware compatibility before committing the device to a new board design.

主な用途
STM32F469AIH6 の用途: 6 件s: Industrial Automation Controller, Audio and DSP Processing, Industrial Networking Gateway, Motor and Motion Control, Human-Machine Interface Controller, Embedded Data Acquisition System.
Industrial Automation Controller
The STM32F469AIH6 fits industrial automation controllers that combine fast control loops with substantial embedded logic. Its 180 MHz Cortex-M4 core and single-precision FPU accelerate filtering, coordinate transforms, and closed-loop calculations, while the complete DSP instruction set supports real-time signal conditioning. The 2 MB Flash allows control software, communications protocols, and diagnostic logic to be consolidated on one device. A 169-UFBGA package also supports compact controller boards, although its fine-pitch land pattern requires careful multilayer routing and qualified assembly.
おすすめ
Audio and DSP Processing
The STM32F469AIH6 is appropriate for audio front ends and embedded signal processors requiring real-time filtering or waveform analysis. Its Cortex-M4 core runs at up to 180 MHz and includes single-precision floating-point and DSP instructions, reducing the computational burden associated with equalization, mixing, modulation, and spectral processing. With 2 MB of Flash, the controller can hold substantial signal-processing code alongside control and interface routines. Designers should allocate DMA, memory bandwidth, and peripheral timing carefully to prevent real-time audio deadlines from being missed.
おすすめ
Industrial Networking Gateway
The STM32F469AIH6 can serve as the application processor in a compact industrial communications gateway. Its 180 MHz 32-bit core provides capacity for protocol stacks, data transformation, status monitoring, and local control, while 2 MB of Flash supports a larger embedded application than many resource-constrained controllers. The device's extensive STM32F4 peripheral set can support multiple serial interfaces and dedicated data movement. Network traffic peaks should be tested with production firmware because protocol processing, logging, and security services can materially affect real-time performance.
おすすめ
Motor and Motion Control
The STM32F469AIH6 is well matched to motor-control and motion-control modules that combine fast sampling with mathematical processing. The 180 MHz Cortex-M4 core can execute control algorithms, while the FPU and DSP instructions support filtering and transforms used in position, speed, or current regulation. Two megabytes of Flash allows the system to combine the control loop, communications, diagnostics, and parameter management. PWM, timer synchronization, analog inputs, and DMA routing must be planned against the exact peripheral configuration in the manufacturer documentation.
おすすめ
Human-Machine Interface Controller
The STM32F469AIH6 can act as the central controller for a sophisticated human-machine interface, combining display updates, touch or keypad input, status logic, and communications. Its 180 MHz processor gives firmware headroom for graphical elements and responsive interaction, and the 2 MB Flash capacity accommodates substantial user-interface and connectivity code. The 169-UFBGA package reduces board area compared with many leaded MCU options but requires a dense fanout layout. External display timing, memory interfaces, and ESD requirements should be validated in the complete system design.
おすすめ
Embedded Data Acquisition System
The STM32F469AIH6 supports compact data-acquisition equipment that must sample, filter, and process sensor data locally. Its DSP instruction set and floating-point unit help accelerate digital filtering and calibration, while the 180 MHz execution rate provides timing margin for control and communications tasks. The 2 MB Flash stores acquisition software, lookup data, calibration tables, and communication routines. Analog sampling accuracy ultimately depends on the selected ADC, reference, anti-alias network, grounding, and layout, so signal-chain specifications must be verified separately from MCU processing performance.

設計ノート
Create the PCB footprint from the official STM32F469xx 169-UFBGA mechanical drawing rather than a generic BGA library. Check ball-pad diameter, solder-mask opening, paste aperture, courtyard, and assembly tolerances against the selected PCB process. Because the package is only 7 x 7 mm with dense ball spacing, plan through-via fanout, layer transitions, and component placement before committing the board outline.
Follow the manufacturer power-supply, decoupling, and external-component recommendations exactly. Place the required input, output, and bypass capacitors at their designated pins with short, low-loop-inductance connections; route sensitive supply paths away from switching nodes and high-current returns. The 180 MHz operating rate also requires a clean clock and correctly filtered supply because supply disturbance can affect execution timing and peripheral accuracy.
Keep clock, reset, boot, and debug nets short and route them away from fast-switching and high-current interfaces. Preserve continuous ground-reference paths beneath signal routes, use solid planes where appropriate, and minimize stubs on sensitive nets. The large number of UFBGA balls can force multilayer routing, so stack-up selection, return-path continuity, and impedance control should be reviewed before layout release.
Do not treat the STM32F429AIH6 or other STM32F4 relatives as automatic substitutes merely because their package and core frequency match. Compare the exact ordering code, memory configuration, pin names, alternate functions, peripheral population, clock limits, and errata. After hardware changes, validate reset and boot behavior, peripheral instances, debug access, clock accuracy, and the production firmware image on the intended board revision.
