STM32F429ZGY6TR - 180MHz Cortex-M4 1MB MCU | STMicroelectronics
MPN: STM32F429ZGY6TR ✓ ActiveSTM32F429ZGY6TR Overview
A microcontroller, or MCU, integrates a processor core, memory, and peripherals into one semiconductor package. The STM32F4 family belongs to the Arm Cortex-M4 microcontrollers, embedded processors, and integrated-circuit hierarchy. Its combination of Cortex-M4 processing, hardware DSP instructions, and a floating-point unit makes it suitable for control systems that must process signals while managing communications, timing, and analog-system inputs.
The STM32F429ZGY6TR provides 32-bit processing at up to 180 MHz, 225 DMIPS, and 1 MB of Flash. The ART Accelerator supports zero-wait-state execution from Flash, while the memory protection unit supports isolated task execution. The datasheet family also supports USB OTG HS/FS, Ethernet, 17 timers, three ADCs, as many as 20 communication interfaces, and camera and LCD-TFT connectivity, making the MCU suitable for complex embedded control platforms.
This device combines the Cortex-M4 core with DSP instructions, an FPU, extensive communication peripherals, and high-speed timing resources. The 143-WLCSP form factor supports dense PCB layouts, but its fine-pitch ball array requires careful PCB design, inspection, and assembly planning. The datasheet family is specified for industrial applications operating from 2.5 V to 3.3 V, allowing integration with common embedded supply rails.
Typical uses include industrial data acquisition, camera and display control, connected embedded equipment, and Ethernet-connected products. Its 180 MHz processing capability supports responsive control loops, while USB and Ethernet interfaces provide paths for data transfer. The compact 4.52 mm by 5.55 mm package can reduce board area when the application can satisfy its fine-pitch assembly and thermal requirements.
Designers should verify the complete pin allocation, exposed-ball requirements, decoupling network, and PCB layout against the manufacturer datasheet before release. The WLCSP package offers high density rather than generous routing space, so fanout and routing must be planned before the first prototype. Firmware qualification should also cover the exact peripheral mix and memory configuration required by the end product.
This page consolidates verified distributor pricing, family-level specifications, same-package replacement candidates, and practical implementation guidance. It separates confirmed target-part data from family-wide datasheet information and identifies missing details rather than estimating package pin assignments or production conditions.

Typical Applications
STM32F429ZGY6TR is suitable for 6 applications: Industrial Data Acquisition, Camera and Image Control, Connected Embedded Equipment, USB Peripheral Controller, Real-Time Motor and Timing Control, Human-Machine Interface Controller.
Industrial Data Acquisition
The STM32F429ZGY6TR fits industrial data-acquisition equipment because its Cortex-M4 core operates up to 180 MHz and delivers 225 DMIPS, while the family provides three ADCs and as many as 20 communication interfaces. It can coordinate sensor sampling, local filtering, and simultaneous communications without relying on separate processing components. Operating from 2.5 V to 3.3 V supports integration with common embedded rails, and the Ethernet and USB interfaces support data transfer. The 4.52 mm by 5.55 mm 143-WLCSP package reduces board area, although designers must follow the fine-pitch land pattern and validate assembly yield before volume production.
Recommended
Camera and Image Control
The STM32F429ZGY6TR is appropriate for camera and image-control subsystems because the manufacturer describes support for camera connectivity alongside 180 MHz Cortex-M4 processing and DSP instructions. Those capabilities allow a designer to coordinate sensor capture, exposure timing, image preprocessing, and control traffic in a compact embedded assembly. Its 1 MB of Flash provides a defined code-storage budget, while the integrated FPU supports floating-point arithmetic in signal-processing workflows. The WLCSP footprint saves board area compared with leaded packages, but camera interfaces and high-speed signals still require careful impedance-controlled routing and schematic verification against the datasheet.
Recommended
Connected Embedded Equipment
The STM32F429ZGY6TR suits connected embedded equipment because its family supports Ethernet, USB OTG HS/FS, and up to 20 communication interfaces while maintaining 225 DMIPS performance at 180 MHz. These resources allow network control, local protocol handling, data logging, and application logic to share one microcontroller platform. The 1 MB Flash configuration is useful for compact firmware, while the 143-WLCSP package assists with space-constrained designs. Engineers should partition network and real-time workloads carefully, validate protocol timing, and place decoupling and high-speed interface routing according to the manufacturer reference design and layout guidance.
Recommended
USB Peripheral Controller
The STM32F429ZGY6TR is suitable for USB peripheral control because the STM32F429 family supports USB OTG HS/FS and provides a 180 MHz Cortex-M4 core with DSP and FPU capabilities. A design can combine USB communications with real-time control, data formatting, and application-specific processing in one compact device. The 2.5 V to 3.3 V operating range supports common embedded power systems, while Ethernet provides an optional path for additional connectivity. The principal engineering considerations are USB signal routing, decoupling, firmware scheduling, and ensuring that the WLCSP assembly process can consistently support the fine-pitch package.
Recommended
Real-Time Motor and Timing Control
The STM32F429ZGY6TR can support real-time motor and timing control because the family includes 17 timers and a Cortex-M4 processor capable of 225 DMIPS at 180 MHz. Its DSP instructions and FPU are useful for control algorithms, while the range of communication interfaces permits integration with sensors, human-interface systems, and supervisory controllers. The compact WLCSP package helps minimize controller board size in space-sensitive equipment. Design work should verify timer-channel assignments, trigger timing, interrupt latency, thermal performance, and the manufacturer-specified decoupling and layout practices before deployment.
Recommended
Human-Machine Interface Controller
The STM32F429ZGY6TR is a strong candidate for a display-oriented human-machine interface because the STM32F429 family supports LCD-TFT connectivity as well as camera, Ethernet, USB, and numerous serial interfaces. At 180 MHz, the controller can update an interface while managing communications and local application logic. Its 1 MB Flash configuration must be balanced against graphics assets and code size, while the 4.52 mm by 5.55 mm WLCSP footprint allows a compact controller section. Display and touch-interface routing should be checked for signal integrity, and the complete ball map and PCB stack-up must be taken from the manufacturer documentation.

Design Notes
Use the STM32F427xx and STM32F429xx manufacturer datasheet land pattern and assembly information for the 143-WLCSP footprint. The supplied web results confirm a 4.52 mm by 5.55 mm package but do not provide the complete ball map, so do not infer pad locations from a generic WLCSP library. Plan escape routing before placement, preserve the manufacturer's recommended decoupling positions, and validate the PCB stack-up, solder-paste stencil, and X-ray inspection process before production.
The STM32F429ZGY6TR operates at 2.5 V to 3.3 V, but the complete external power network still requires careful implementation. Follow the manufacturer datasheet for exact input, output, internal-regulator, and decoupling connections. Place required capacitors directly at the relevant package balls, maintain short return paths, and account for USB, Ethernet, and other I/O current behavior. Because no exact pin or capacitor table was included in the verified snippets, component values and rail connections must be verified against DM00071990.
The high-performance 180 MHz Cortex-M4 core and USB or Ethernet connectivity make intentional layout more important than physical package density alone. Separate sensitive analog paths from switching and high-current digital routes, use a continuous ground reference where appropriate, and apply manufacturer-recommended termination and impedance rules to external interfaces. For the fine-pitch WLCSP, use short escapes and adequate assembly clearances, then verify the final design through DRC and manufacturing review.
Do not treat the STM32F429ZIY6TR and STM32F429ZIY6JTR as automatic substitutes merely because the verified comparison lists the same 143-WLCSP package class. Their listed Flash capacity is 2 MB rather than the target's 1 MB, and the suffix distinction may affect ordering or qualification. Confirm the exact temperature grade, peripheral configuration, memory map, pin definitions, boot behavior, and qualification using the official ordering-information and datasheet sections before approving a replacement.
Compliance Information
The supplied verified snippets do not explicitly state compliance status for the target. Compliance must be confirmed from STMicroelectronics product documentation or the distributor product attributes before qualification.
