STM32F429IIH6TR - 180MHz Cortex-M4 2MB MCU | STMicroelectronics (Tape & Reel)
料号： STM32F429IIH6TR ✓ 量产中STM32F429IIH6TR 概述
A Cortex-M4 microcontroller is a reduced-instruction-set controller within the ARM processor family. The STM32F429II combines a 32-bit core, floating-point hardware, DSP instructions, extensive memory, GPIO, timers, communication peripherals, and analog resources in one device. Its hierarchy is microcontroller -> embedded processor -> ARM Cortex-M -> Cortex-M4 microcontroller.
The verified core specifications include an Arm Cortex-M4 CPU with FPU, ART Accelerator capability, operation up to 180 MHz, and 225 DMIPS at 1.25 DMIPS/MHz. The device also provides 2 MB of Flash configured as 2M x 8. DSP instructions support audio, signal-processing, and control workloads where floating-point or fixed-point arithmetic is useful.
The STM32F429II family is positioned for applications requiring greater processing capability and memory than smaller Cortex-M devices. Its integrated resources can reduce external component count, while the 10 x 10 mm UFBGA package supports compact high-density designs. Exact peripheral availability, pin assignments, electrical limits, and memory-map details should be checked against the manufacturer documentation for the selected ordering code.
Typical applications include industrial automation, communications equipment, audio and digital signal processing, motor and motion control, human-machine interfaces, networked embedded systems, and consumer electronics. The Cortex-M4 DSP and FPU features are particularly relevant when the control loop must process sampled signals or perform filtering without relying solely on an external processor.
A critical design consideration is that the 176+25 UFBGA package requires a PCB land pattern, solder-mask design, and manufacturing process capable of handling fine-pitch balls. Designers should also confirm power sequencing, decoupling, clock configuration, boot settings, pin multiplexing, and peripheral-specific electrical constraints before schematic release.
This product page consolidates verified source specifications, package information, application guidance, and explicit data gaps. It does not invent electrical values or pin names that were absent from the supplied web data, and it separates confirmed facts from parameters requiring datasheet review.

典型应用
STM32F429IIH6TR 适用于 6 应用s: Industrial Automation Controller, Audio and Digital Signal Processing, Communications Gateway, Motor and Motion Control, Human-Machine Interface Controller, Consumer Embedded Product.
Industrial Automation Controller
The STM32F429IIH6TR fits industrial automation when a controller must combine real-time control with communications and data handling. Its Arm Cortex-M4 core operates up to 180 MHz, while the FPU and DSP instructions support calculations used in motion, filtering, and feedback control. The 2 MB of Flash provides room for application firmware, diagnostics, and communication stacks. A 176+25 UFBGA package also supports compact controller boards, although fine-pitch assembly and industrial temperature requirements must be confirmed against the exact device documentation.
推荐
Audio and Digital Signal Processing
The Cortex-M4 FPU and DSP instructions make STM32F429IIH6TR suitable for embedded audio and signal-processing workloads. The core can execute up to 180 MHz, enabling real-time filtering, mixing, modulation, and control functions, while 2 MB of Flash supports firmware and lookup data. Designers should confirm the required audio interface, sample-rate support, DMA resources, and memory map in the manufacturer documentation. The package is compact but its 10 x 10 mm UFBGA construction requires careful PCB layout and manufacturing capability.
推荐
Communications Gateway
STM32F429IIH6TR can serve as the control processor in an embedded communications gateway where high processing throughput and local memory are valuable. The 180 MHz Cortex-M4 core provides computational capacity for protocol handling, packet processing, routing logic, and supervisory functions. Its MPU support can help isolate software regions, while DSP instructions can assist with signal conditioning. The actual network interfaces, protocol support, and security requirements must be verified from the exact datasheet; no unverified Ethernet or wireless capability is assumed here.
推荐
Motor and Motion Control
The STM32F429IIH6TR is appropriate for motor and motion-control subsystems that benefit from deterministic computation and floating-point or DSP operations. The Cortex-M4 core at up to 180 MHz can execute control algorithms, while the FPU improves handling of real-valued calculations and DSP instructions support signal transformations. The 2 MB of Flash can hold firmware, calibration data, and control tables. Designers must verify timer capabilities, encoder interfaces, PWM resources, analog channels, and electrical operating limits before final selection.
推荐
Human-Machine Interface Controller
STM32F429IIH6TR can act as the main controller for a compact human-machine interface that combines display, touch, keypad, and communications functions. Its high-performance Cortex-M4 core leaves processing headroom for user-interface logic, data formatting, and control messages, while the MPU supports protected software organization. The 176+25 UFBGA package helps reduce board area in space-constrained products. Before layout, confirm the required display and touch interfaces, pin multiplexing, package ball assignments, and board manufacturing capability.
推荐
Consumer Embedded Product
The STM32F429IIH6TR is suitable for compact consumer products that need more processing capability than a basic microcontroller, especially when local control, interface handling, or signal processing is required. The 2 MB of Flash supports a moderate embedded application, and the Cortex-M4 FPU helps manage responsive control logic. Its UFBGA package enables small board layouts but complicates assembly, inspection, and repair. Firmware developers should evaluate boot behavior, memory usage, low-power requirements, and production test coverage before selecting it for a consumer design.

设计说明
The STM32F429IIH6TR uses a 176+25 UFBGA package, so the PCB must implement the exact ball pattern, solder-mask openings, paste apertures, and assembly land geometry specified by the manufacturer package drawing. Do not copy a generic BGA footprint solely from the ball count. Confirm the pin-1 orientation, ball map, pad dimensions, and production tolerance with the official STM32F429II documentation before releasing the layout.
Plan the power rails and decoupling around the exact STM32F429IIH6TR electrical requirements rather than assumptions based only on the Cortex-M4 core frequency. The supplied data does not include the device's input-voltage range, absolute maximum ratings, current consumption, or power-sequencing requirements, so those values must be retrieved from the manufacturer datasheet before schematic approval. Place required bypass capacitors adjacent to the relevant power balls and follow the package-specific layout recommendations.
Reserve all pins for boot, debugging, clocking, reset, and configuration requirements before assigning application interfaces. The verified data confirms a 176+25 UFBGA package but does not provide a complete numbered pin list, so pin multiplexing and alternate-function assignments remain [DATA_NEEDED: complete package pinout]. Review the official datasheet and development-board schematic to prevent conflicts between debug access and production functions.
For high-speed digital interfaces, clocks, or memory-connected external devices, route signals with controlled impedance and minimize discontinuities. Keep sensitive analog and digital return paths organized, provide continuous reference planes where appropriate, and account for the UFBGA escape-routing limitations. The supplied material does not identify the STM32F429IIH6TR high-speed peripheral pinout or transceiver requirements, so interface-specific layout values must be taken from the official datasheet.
合规信息
The supplied verified snippets do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. A cross-reference page mentioning RoHS or REACH was not treated as authoritative component certification evidence.
