STM32F429IIT6J - 180MHz 2MB Cortex-M4 MCU | STMicroelectronics
MPN: STM32F429IIT6J ✗ Cuối đờiSTM32F429IIT6J Tóm tắt
A microcontroller is a programmable semiconductor system that integrates a processor core, memory and peripherals into one device. In the product hierarchy, the STM32F429 belongs to STM32F4 microcontrollers, then 32-bit embedded MCUs, then integrated circuits and semiconductors. Its Cortex-M4 core combines general-purpose control with floating-point-oriented workloads, while the larger Flash capacity supports application code, protocol stacks, firmware updates and graphics or control logic.
The verified product information establishes a maximum core frequency of 180 MHz and 2 MB of Flash. The STM32F429 family also supports devices in the STM32F427xx and STM32F429xx families based on the same high-performance Arm Cortex-M4 architecture, as stated on the official STMicroelectronics product page. Exact RAM size, GPIO count, supply range, peripheral list and operating-temperature limits were not included in the supplied evidence and therefore are not asserted here.
A 176-LQFP package provides a large lead count for designs requiring extensive external connectivity. Such packages are mechanically suited to leaded through-hole assembly and are common in industrial control equipment where a higher pin count is preferable to a very small fine-pitch package. The verified 24 x 24 mm body size enables the PCB footprint to be planned with adequate spacing for assembly and inspection.
Typical uses include industrial automation, communications equipment, motor control, data acquisition, human-interface systems and embedded gateways. Firmware selection depends on the exact peripheral set, memory requirements and operating conditions, which should be confirmed against the manufacturer documentation for the ordered device. The STM32F429IIT6J is therefore most appropriate when a design specifically targets the STM32F429 platform and its 180 MHz Cortex-M4 processing capability.
The key procurement check is package and firmware continuity. Because the orderable suffix J distinguishes this MPN, engineers should confirm package, grade, temperature range and software-support requirements before substitution. The available evidence identifies STM32F429IIT6J as obsolete in one cross-reference result, so lifecycle status should be reconfirmed with STMicroelectronics or an authorized distributor before a production release.
This page consolidates the verified manufacturer identification, distributor package information, availability context and replacement research. It also distinguishes confirmed data from missing technical fields rather than estimating unverified electrical specifications.

Ứng dụng tiêu biểu
STM32F429IIT6J phù hợp cho 6 Áp dụngs: Industrial Automation Controller, Communications Gateway, Motor Control System, Data Acquisition System, Human-Machine Interface, Embedded Data Logger.
Industrial Automation Controller
The STM32F429IIT6J fits an industrial automation controller that needs a 180 MHz Cortex-M4 core, 2 MB of Flash and a high-pin-count 176-LQFP footprint. The processing headroom can support control loops, communications stacks and supervisory logic in one embedded device, while the LQFP package exposes more terminals than a compact MCU. The supplied data does not confirm the exact GPIO count, temperature grade or isolated-interface capability, so those items must be checked in the manufacturer documentation before qualification.
Được đề xuất
Communications Gateway
A communications gateway can use the STM32F429IIT6J's verified 180 MHz Arm Cortex-M4 performance and 2 MB Flash for protocol processing, buffering and application firmware. The 176-LQFP package is useful when the design needs a large complement of control and communication connections. Ethernet, USB, transceiver interfaces and supported baud rates were not specified in the supplied evidence, so gateway suitability must be based on the exact peripheral list and pinout rather than processor frequency alone.
Được đề xuất
Motor Control System
The STM32F429IIT6J is a plausible candidate for a motor-control system because its 180 MHz Cortex-M4 core provides substantial real-time processing capability and its 176-LQFP package offers extensive external connectivity. The 2 MB Flash also allows more complex algorithms and diagnostics than a very small microcontroller. Timers, PWM outputs, encoder interfaces, ADC characteristics and operating-temperature limits were not included in the verified data, so motor-loop timing and safety requirements must be validated before selecting it.
Được đề xuất
Data Acquisition System
For data acquisition, the STM32F429IIT6J combines a 180 MHz processing core with 2 MB Flash for buffering, calibration and communications firmware. Its 176-LQFP package can provide the pin count needed for multiple digital sensors, storage interfaces and status signals. The verified record does not state ADC resolution, converter speed, sample-rate support, input voltage range or operating temperature, so an acquisition design must confirm the analog specifications and sensor-interface timing in the official documentation.
Được đề xuất
Human-Machine Interface
The STM32F429IIT6J can serve as the central processor in a human-machine interface because its 180 MHz Cortex-M4 core and 2 MB Flash support graphical state handling, input processing and communications. The 176-LQFP package is appropriate when a design requires many discrete panel signals and external memory connections. Display interface specifications, touch-controller support and available USB or Ethernet functions are not present in the supplied evidence, so interface selection must follow the verified peripheral list rather than assume them.
Được đề xuất
Embedded Data Logger
The STM32F429IIT6J's 2 MB Flash and 180 MHz Cortex-M4 processing capability make it suitable for a configurable embedded logger that stores events locally and forwards them through a communications interface. The large LQFP package can simplify access to storage, external memory and status controls. Storage type, endurance, write protection and RTC support were not supplied in the verified evidence. Designers should therefore verify the memory map, bootloader behavior and environmental grade before using the part in a field-deployed logger.

Hướng dẫn chọn lựa
Ghi chú thiết kế
Treat the 176-LQFP footprint as a documentation-controlled layout item. The supplied evidence confirms a 24 x 24 mm package but does not provide the complete terminal map, so do not generate land patterns, pin-1 orientation or net assignments from memory. Download the official package drawing and exact orderable-part pinout, then cross-check every power, ground, boot, clock and signal connection against the schematic before fabrication.
Do not treat a related STM32 MPN as a substitute merely because it uses a Cortex-M core or the same STM32 family name. A valid replacement must be checked for identical 176-LQFP dimensions, terminal numbering, alternate-function mapping, power architecture, memory organization, clock limits, peripheral set and firmware compatibility. The supplied cross-reference data does not establish a true drop-in equivalent, so any redesign requires schematic, PCB and software review.
Use the manufacturer thermal information to determine the maximum junction temperature, package thermal resistance and PCB copper requirements. The supplied data confirms a 176-LQFP package but does not provide power dissipation, ambient limits or thermal resistance, so no thermal calculation can be made here. Estimate only after clock, peripheral, I/O and supply conditions are known, and label all derived values as estimates with their inputs.
Preserve the exact high-speed and sensitive-signal routing strategy supported by the STM32F429 reference documentation. Separate clocks, high-current outputs and analog inputs where the application requires it, and follow the manufacturer recommendations for decoupling and grounding. The current evidence does not identify the power pins or bypass requirements, so those values must come from the official pinout and hardware guidelines rather than generic assumptions.
Thông tin tuân thủ
The supplied verified snippets do not provide a reliable compliance statement for this exact MPN. RoHS, REACH, AEC-Q100, lead-free, halogen-free and conflict-minerals status must be confirmed from the current STMicroelectronics product documentation or supplier documentation.
