STM32F429VIT6TR - 180MHz Cortex-M4 2MB MCU | STMicroelectronics (Tape & Reel)
料号： STM32F429VIT6TR ✗ 停产STM32F429VIT6TR 概述
A microcontroller is a programmable semiconductor that integrates a CPU core, memory, peripherals, and communication interfaces into one device. The STM32F429 belongs to the STM32F4 high-performance MCU family, where the ARM Cortex-M4 core provides deterministic embedded-control processing with single-precision floating-point hardware and DSP instructions. Its system hierarchy is ARM Cortex-M processor -> STM32 family -> STM32F4 series -> 32-bit Flash MCU.
The Cortex-M4F core provides up to 225 DMIPS and 1.25 DMIPS/MHz, while the ART Accelerator enables zero-wait-state execution from Flash. The device supports operation at up to 180 MHz and includes 2 MB of Flash plus 256 KB of SRAM. The supplied comparison data also identifies 3.3 V and 2.5 V device variants, but the exact STM32F429VIT6TR supply-voltage range and detailed electrical limits require confirmation from the manufacturer datasheet.
Its feature set targets demanding embedded systems requiring substantial memory and graphical connectivity. The retrieved sources identify an LCD parallel interface, along with communication and control peripherals suitable for industrial automation, human-machine interfaces, communications equipment, test and measurement, and connected embedded products. The 100-pin LQFP package provides a conventional leaded footprint that is easier to inspect and solder than fine-pitch alternatives.
When designing around STM32F429VIT6TR, validate pin multiplexing, clock limits, memory-mapped peripheral addresses, and package-specific alternate functions before committing a PCB. Power, decoupling, boot configuration, programming access, and thermal performance should follow the STMicroelectronics datasheet and hardware-design guidance. Verify the complete pinout against the exact 100-pin package rather than relying on another STM32F4 variant.

典型应用
STM32F429VIT6TR 适用于 6 应用s: Industrial HMI Controller, Communications Gateway, Test and Measurement Instrument, Real-Time Signal Processing Controller, Data Acquisition and Control Panel, Embedded Network Appliance.
Industrial HMI Controller
The STM32F429VIT6TR fits an industrial human-machine interface because its 180 MHz Cortex-M4F core provides up to 225 DMIPS while retaining 2 MB of Flash and 256 KB of SRAM. The verified device feature set includes a parallel LCD interface for directly driving compatible displays, reducing reliance on an external display controller. The Cortex-M4F FPU and DSP instructions are useful when combining touch-responsive controls with data filtering or graphics-related processing. Before schematic release, confirm the exact LCD signal multiplexing, panel voltage requirements, timing, and unused-pin assignments in the manufacturer pin table.
推荐
Communications Gateway
STM32F429VIT6TR can serve as the central controller in a communications gateway where protocol handling, buffering, and management tasks compete for processor time. Its 180 MHz Cortex-M4F core, DSP instructions, and 2 MB Flash provide substantial application-code capacity, while 256 KB of system SRAM supports packet staging and protocol state. The large 100-pin LQFP also offers more peripheral assignment options than smaller packages, subject to exact multiplexing. Firmware should reserve the required clocks, memory, DMA channels, and communication peripherals, then validate timing under maximum traffic.
推荐
Test and Measurement Instrument
The STM32F429VIT6TR is appropriate for embedded test equipment that combines real-time acquisition, signal analysis, calibration, and a local user interface. Its Cortex-M4F processor provides hardware floating-point and DSP instructions at up to 180 MHz, supporting filter and control calculations that would burden a smaller microcontroller. With 2 MB Flash and 256 KB SRAM, the device can hold substantial firmware and working data without an immediate external memory requirement. Designers should still map ADC, timer, DAC, display, and communication pins from the exact 100-pin datasheet before finalizing signal-chain isolation and analog layout.
推荐
Real-Time Signal Processing Controller
STM32F429VIT6TR fits real-time signal-processing control because its 180 MHz Cortex-M4F core includes a single-precision FPU and DSP instructions. Those hardware features improve suitability for digital filtering, modulation-related calculations, control loops, and fixed computational workloads compared with a basic Cortex-M0-class MCU. The 2 MB Flash capacity accommodates algorithms and look-up data, while the 256 KB SRAM supports active working buffers. Performance claims must be benchmarked with the intended compiler and memory configuration; DMA and cache or bus contention behavior can materially affect real-time execution.
推荐
Data Acquisition and Control Panel
STM32F429VIT6TR can coordinate sensor acquisition, local controls, data logging, and a parallel-display interface in a compact embedded panel. Its verified 225 DMIPS performance and 256 KB system SRAM provide room for sampling tasks and control state, while the 2 MB Flash supports application firmware and calibration tables. The Cortex-M4 DSP and FPU features assist with filtering and scaling of acquired values. Exact ADC channels, timer inputs, DMA assignments, and LCD pins are design-dependent; verify them directly against the STM32F429VI documentation rather than a generic STM32F4 pinout.
推荐
Embedded Network Appliance
STM32F429VIT6TR is suitable for an embedded network appliance requiring local protocol processing, configuration storage, diagnostics, and a user interface. The 180 MHz Cortex-M4F core handles multiple interrupt-driven tasks, while 2 MB Flash and 256 KB SRAM reduce pressure on external memory for moderate workloads. Its parallel LCD interface can support local status displays, and the 100-pin LQFP exposes a broad selection of multiplexing options. For production networking, validate the selected Ethernet or other communications peripheral, pin conflicts, buffer requirements, boot behavior, and sustained throughput using representative traffic.

设计说明
Begin the schematic and PCB review from the exact 100-pin STM32F429VI pin table rather than a generic STM32F4 drawing. Classify every required boot, clock, reset, debug, communication, display, and analog signal before assigning alternate functions. The LQFP footprint is larger and easier to probe than a fine-pitch QFN, but its 0.5 mm lead pitch still requires adequate pad geometry, solder mask clearance, and assembly-process capability.
Use the manufacturer power-supply and decoupling requirements for the selected operating mode and peripheral set. The retrieved distributor information identifies 2.5 V and 3.3 V variants, but the exact STM32F429VIT6TR voltage range and current limits are not supplied. Do not infer a regulator target from the nominal label alone. Validate startup current, analog-supply sequencing, voltage tolerances, and decoupling against the exact datasheet before releasing power circuitry.
A shared Cortex-M4 core and LQFP footprint do not make different STM32F4 orderable devices automatically interchangeable. Before substituting STM32F429VGT6, STM32F439VIT6, or STM32F437VIT6, compare every used pin, alternate-function mapping, peripheral set, clock limit, memory resource, electrical maximum, startup file, and linker configuration. Package-fit checks and basic frequency equality are necessary but not sufficient for a safe drop-in decision.
合规信息
The supplied verified data does not state the target part's RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not treated as applicable because the exact automotive qualification of STM32F429VIT6TR is not stated in the verified source data.
