STM32F429ZIY6JTR - 180MHz Cortex-M4 MCU, 2MB Flash | STMicroelectronics
料号： STM32F429ZIY6JTR ✓ 量产中STM32F429ZIY6JTR 概述
An STM32F4-series microcontroller is a programmable embedded-system platform combining an Arm Cortex-M processor core, memory, communications peripherals, timers, analog conversion functions, and direct-memory-access capabilities. Within the product hierarchy, it is a 32-bit RISC microcontroller based on the Cortex-M4 core, with the Cortex-M architecture forming part of the Arm embedded ecosystem. The STM32F429 extends the STM32F4 family with high-performance processing and connectivity suited to complex embedded control systems.
The Cortex-M4 core includes DSP instruction support and a hardware floating-point unit, while the manufacturer documents up to 225 DMIPS performance. The ART Accelerator improves Flash-memory access behavior, and the device includes 17 timers, three ADCs, and approximately 20 communication interfaces. These resources allow firmware to combine real-time control, signal acquisition, communications, and human-interface or display functions on one integrated device.
The 180 MHz operating frequency supports compute-intensive control loops and media-oriented firmware, while the 2 MB Flash capacity accommodates larger embedded applications, bootloader logic, and graphical or communication code. Its communication set includes USB OTG HS/FS and Ethernet, making it suitable for connected industrial, communications, medical, and consumer equipment. The datasheet also identifies camera and LCD-TFT support, extending its usefulness for embedded imaging and display systems.
Typical applications include industrial automation controllers, Ethernet-connected equipment, USB data acquisition devices, motor-control systems, medical monitoring instruments, camera-based products, and LCD-TFT human-interface panels. For designs requiring more exposed pins, the same STM32F429 family includes lower-pin-count variants, while the target JTR ordering code selects the 143-UFBGA/WLCSP implementation.
Designers must treat the WLCSP package as a fine-pitch assembly challenge and plan fine-pitch inspection, assembly capability, and board-layout validation carefully. Power, ground, decoupling, and high-speed signal routing should follow the manufacturer's pinout and layout guidance. Firmware development is best based on the exact device revision, memory map, and peripheral configuration identified in the STM32CubeMX and STM32CubeIDE device databases.
This page consolidates verified manufacturer and distributor specifications, identifies the closely related ordering variant found in the supplied cross-reference results, and separates confirmed data from fields requiring device-specific verification. The comparison and design notes focus on package continuity, memory differences, tool compatibility, and practical implementation considerations not presented as a substitute for the official datasheet.

典型应用
STM32F429ZIY6JTR 适用于 6 应用s: Industrial Automation Controller, Ethernet-Connected Embedded Equipment, USB Data-Acquisition Device, Motor Control and Power Monitoring, Medical Monitoring Instrument, Camera and LCD-TFT User Interface.
Industrial Automation Controller
The STM32F429ZIY6JTR fits an industrial automation controller because its 180 MHz Arm Cortex-M4 core provides real-time processing while the 2 MB Flash accommodates control, communications, and diagnostics firmware. Its 17 timers support motor, PWM, input-capture, and encoder-related functions, while three ADCs handle analog process inputs. Ethernet and CANbus connectivity allow the controller to participate in machine and plant networks. The trade-off is the 143-UFBGA/WLCSP footprint, which demands fine-pitch assembly capability and careful validation of the manufacturer land pattern.
推荐
Ethernet-Connected Embedded Equipment
The STM32F429ZIY6JTR is appropriate for Ethernet-connected embedded equipment because the STM32F429 family includes Ethernet alongside USB OTG HS/FS, CANbus, UART/USART, SPI, and I2C. Its Cortex-M4 core operates at up to 180 MHz and is documented at up to 225 DMIPS, providing capacity for protocol handling, control logic, and service interfaces. The 2 MB Flash supports a bootloader and application firmware, while 256 KB of SRAM supports active networking tasks. Board planners must provide controlled impedance routing and robust power and ground distribution around the fine-pitch WLCSP.
推荐
USB Data-Acquisition Device
The STM32F429ZIY6JTR fits a USB data-acquisition system that combines high-speed digital transfer with analog measurement and real-time processing. It provides USB OTG HS/FS, three ADCs, multiple timers, and a 180 MHz Cortex-M4 core with DSP and FPU support. The DSP capability can accelerate filtering and signal-processing tasks, while the FPU supports floating-point control and analysis routines. The 2 MB Flash is useful for firmware, calibration tables, and protocol code. Engineers must confirm analog front-end requirements, USB routing, decoupling, and exposed-pin availability before schematic release.
推荐
Motor Control and Power Monitoring
The STM32F429ZIY6JTR is suitable for motor-control and power-monitoring equipment because its 17 timers provide resources for PWM generation, input capture, and timing functions, while three ADCs support current, voltage, and position feedback. The 180 MHz Cortex-M4 core can execute control algorithms concurrently with communications and monitoring tasks. Ethernet, USB, and CANbus provide paths for configuration, telemetry, and diagnostics. The principal design constraint is that the 143-UFBGA/WLCSP package may require more demanding assembly and inspection processes than a leaded package.
推荐
Medical Monitoring Instrument
The STM32F429ZIY6JTR can support a medical monitoring instrument that combines real-time sensing, communications, and a compact control board. Its 180 MHz Cortex-M4 core, three ADCs, 17 timers, and 256 KB of SRAM provide resources for sampling, filtering, alarms, and user-interface logic. The 2 MB Flash can hold application code, communication stacks, and controlled boot infrastructure. Compliance must be assessed independently of device capability: the supplied sources do not confirm medical-device qualification, IEC standards, RoHS, REACH, or the exact operating-temperature grade.
推荐
Camera and LCD-TFT User Interface
The STM32F429ZIY6JTR is appropriate for camera-based products and LCD-TFT interfaces because the STM32F429 family explicitly supports camera and LCD-TFT functions. Its Cortex-M4 processor provides real-time pixel or control processing, with DSP and FPU assistance for image and control algorithms. The 2 MB Flash provides additional room for graphics and control firmware, while USB, Ethernet, and other serial interfaces support data transfer and configuration. The compact 143-UFBGA/WLCSP package helps reduce board area but increases assembly complexity and requires careful display-interface layout validation.

设计说明
Use the exact STMicroelectronics 143-UFBGA/WLCSP land pattern, ball map, and assembly guidelines rather than a generic WLCSP footprint. The package is only 4.52 mm by 5.55 mm, so small differences in pad geometry or solder-mask definition can affect printability and assembly yield. Confirm the PCB stack-up, pad dimensions, stencil thickness, solder alloy, placement profile, and inspection method with the assembly capability that will build the product. The available package library lacks a 143-UFBGA diagram, so no fabricated land pattern is supplied here.
Follow the manufacturer pinout to place every required power, ground, reference, and decoupling connection before committing the board layout. For a 180 MHz Cortex-M4 MCU, inadequate supply decoupling can affect execution timing, analog measurement, communications, and electromagnetic behavior even when the logic itself is correct. Use the values and capacitor recommendations in the official datasheet, provide a low-impedance ground-plane structure, and keep high-current and sensitive analog routing separated where the application permits. Exact capacitor values and voltage tolerances require verification in the manufacturer document.
Do not select a replacement solely because it is labeled STM32F429 and uses the same WLCSP outline. The supplied cross-reference data identifies STM32F429ZIY6TR as the closest candidate, but it does not explain the J character in STM32F429ZIY6JTR. Before substitution, compare the complete manufacturer ordering information, temperature grade, pin names, electrical limits, peripheral population, package drawing, qualification status, and lifecycle status. In particular, do not infer RoHS, REACH, AEC-Q100, or industrial-temperature status from the ordering code without supporting documentation.
Plan the PCB for high-speed digital behavior and sensitive analog measurement even though the MCU itself operates from 3.3 V. USB, Ethernet, camera, and LCD-TFT interfaces can impose demanding edge-rate, return-path, and impedance-control requirements. Match the manufacturer reference layout for external components, preserve the intended pin and ball assignments, and validate the final stack-up with the intended fabricator. The exact I/O speeds, impedances, and interface constraints should be taken from the relevant datasheet sections because those values were not included in the supplied search snippets.
合规信息
The verified snippets identify the device as active but do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. These fields remain unknown rather than being inferred from the ordering code.
