STM32F429ZIT6TR - 2MB Flash 180MHz Cortex-M4 MCU | STMicroelectronics (Tape & Reel)

The STMicroelectronics STM32F429ZIT6TR is a high-performance 32-bit ARM Cortex-M4 microcontroller with FPU operating at up to 180 MHz, integrating 2 MB of flash memory, 256 KB of SRAM, and a 144-pin LQFP (20x20 mm) package. What is a microcontroller? A microcontroller (MCU) is a compact integrated circuit that governs a specific operation in an embedded system, combining a processor core, flash memory, SRAM, and programmable peripherals on a single chip. The STM32F429ZIT6TR sits within the STM32F4 series, part of the broader STM32 family of 32-bit ARM Cortex-M microcontrollers, which in turn belongs to the general hierarchy of embedded processors and system-on-chip devices used across industrial, consumer, and IoT applications. Key features include the ARM Cortex-M4 core with single-precision FPU and DSP instructions, ART Accelerator enabling 0-wait-state execution from flash, and 225 DMIPS (1.25 DMIPS/MHz at 180 MHz). Memory resources total 2 MB of flash and 256 KB of system SRAM plus 4 KB of backup SRAM. Peripheral integration is extensive: three 12-bit ADCs, two DACs, 12 general-purpose 16-bit timers plus two 32-bit timers, multiple USART/SPI/I2C interfaces, USB OTG full-speed and high-speed, 10/100 Ethernet MAC, and a TFT-LCD parallel interface (8080/6800) that supports up to XGA resolution. Supply voltage range is 1.8V to 3.6V (3.3V typical). Architecturally, the adaptive real-time (ART) accelerator pairs with the dual-bank flash organization to support read-while-write operation, which is critical for in-field or over-the-air firmware updates. Clock generation supports an external crystal and internal RC sources feeding a PLL that synthesizes the 180 MHz system clock, while a memory protection unit (MPU) supports robust RTOS partitioning and a cryptographic/hash engine (on related F4 variants) provides hardware acceleration for security workloads. Typical applications include industrial control and automation, HMI panels with TFT displays, motor drives, IoT gateways using Ethernet, and medical instrumentation where real-time control and rich connectivity are required. The device is also widely used in audio processing thanks to its DSP extensions and I2S peripherals, and in graphical user interfaces via the integrated LCD-TFT controller. Design consideration: decouple every VDD pin with 100 nF X7R capacitors placed close to the pins, add a 4.7 uF bulk capacitor near the regulator, and filter the VDDA analog supply with a ferrite bead plus 10 nF + 1 uF decoupling; budget PCB copper area for thermal dissipation in high-load designs where the MCU draws sustained currents above 100 mA. This page synthesizes distributor availability, same-package drop-in alternatives, and practical design notes not found in the STMicroelectronics datasheet, giving engineers a complete evaluation resource.

The STMicroelectronics STM32F437IIH6 is a high-performance 32-bit ARM Cortex-M4F microcontroller with FPU and DSP extensions, operating at up to 180 MHz and integrating 2 MB of dual-bank Flash plus 256 KB of SRAM, housed in a 176-ball UFBGA (10x10 mm) package. It combines an ART Accelerator that enables zero-wait-state Flash execution, hardware AES/DES/SHA accelerators, a TFT-LCD controller, a parallel camera interface, and the Chrom-ART 2D graphics engine on a single die. An ARM Cortex-M4F microcontroller is a 32-bit embedded processor core designed for applications demanding a balance of performance, power efficiency, and real-time digital signal processing. The 'F' suffix denotes the inclusion of a single-precision hardware floating-point unit (IEEE 754), which accelerates transcendental and fractional arithmetic commonly required in control loops, audio codecs, and DSP filters. In the system hierarchy, the STM32F437IIH6 sits at the application processor tier, above Cortex-M0+ sensor nodes but below Cortex-A application processors, often serving as the central controller in industrial, consumer, medical, and IoT-edge systems. Key differentiating features of the STM32F437IIH6 include a Cortex-M4F core delivering 225 DMIPS / 2.14 CoreMark/MHz, dual-bank Flash supporting read-while-write firmware upgrades, an integrated TFT-LCD controller capable of XGA-class resolutions, an 8/14-bit parallel camera interface, and hardware accelerators for AES-128/192/256, DES/3DES, and SHA-1/MD5/SHA-2 hash functions. Connectivity is extensive: USB 2.0 OTG HS/FS, 10/100 Ethernet MAC with IEEE 1588, two CAN 2.0B, three I2C, six SPI, four USART plus four UART, and an SDIO interface. Technically, the device is fabricated on a 90 nm CMOS process and integrates an adaptive real-time (ART) memory accelerator that effectively eliminates Flash wait states at the full 180 MHz clock. The 1.8 V to 3.6 V supply range supports direct battery and USB-bus operation. The integrated 12-bit ADC (up to 3 MSPS, three channels of 1 MSPS each) and dual 12-bit DAC channels simplify mixed-signal designs. Multiple low-power modes (Sleep, Stop, Standby with RTC) draw as little as 2.4 µA in Standby with the RTC running. Typical applications include industrial motor-control inverters, human-machine interface (HMI) panels with TFT displays, medical patient monitors, networked IoT gateways, and high-end consumer audio/graphics products. In an HMI panel, for instance, the TFT-LCD controller drives the display directly while the Chrom-ART engine handles 2D rendering, freeing the Cortex-M4F for application logic and communication stacks. When designing with the STM32F437IIH6, pay attention to power-supply decoupling: a 100 nF ceramic capacitor close to every VDD pin and a 4.7 µF bulk capacitor at the regulator output are mandatory. Route the USB and Ethernet differential pairs per the 90 Ω impedance guideline in RM0090. For low-power RTC retention, connect VBAT to a backup battery or super-capacitor; without this the backup registers and RTC lose state on power loss.

The exact RAM size, supply range, temperature range, and pin assignments are not present in the supplied verified snippets and therefore remain marked as data needed. A microcontroller, or MCU, is a semiconductor device that integrates a processor core, memory, peripherals, and communication interfaces into one compact component. The STM32F446 belongs to the STM32F4 high-performance family and is positioned above simpler control MCUs: its Cortex-M4 core supports digital signal processing and floating-point work, while the STM32 ecosystem provides development tools, firmware libraries, and board resources. The verified distributor listing identifies the device as a 32-bit Cortex-M4 MCU with 180 MHz operation and 256 KB of Flash. The STMicroelectronics family page also identifies the STM32F446 line with dual Quad SPI, SDRAM, and audio interfaces. These features make it suitable for systems requiring substantial peripheral connectivity alongside real-time control, signal processing, communications, or external-memory access. The device can serve as the central controller in industrial automation, audio equipment, communications infrastructure, instrumentation, and connected embedded products. Its 180 MHz execution rate provides more compute headroom than lower-frequency general-purpose MCUs, while DSP instructions and an FPU are valuable for filtering, control loops, and other arithmetic-intensive workloads. Peripheral requirements must still be checked against the exact package pinout and device datasheet. A key design consideration is software and peripheral migration. Firmware should be developed against the exact STM32F446 device definition, clock tree, memory map, and CubeMX configuration rather than assuming compatibility with every STM32F4 member. Power sequencing, decoupling, exposed-ball access, programming, and signal-integrity requirements depend on the verified 81-WLCSP layout and board design. This page consolidates the supplied distributor and manufacturer findings with explicit data gaps, rather than inventing specifications. It also avoids presenting generic STM32 cross-references as true drop-in replacements because the supplied search results did not verify same-package, pin-to-pin alternatives.

STM32F446MEY6TR - 180MHz Cortex-M4 512KB MCU | STMicroelectronics

STMicroelectronics STM32F446MEY6TR is an Arm Cortex-M4 32-bit RISC microcontroller operating up to 180 MHz, with 512 KB of Flash memory and DSP and FPU capability, in an 81-WLCSP package measuring 3.80 mm by 3.69 mm. The device is positioned for compact, high-performance embedded systems requiring substantial processing speed, local program storage, and extensive serial peripherals. A microcontroller is a semiconductor device that integrates a processor core, memory, and peripherals into one package. The STM32F4 series belongs to the embedded-processing hierarchy: Arm Cortex-M core, 32-bit RISC processor, microcontroller, and embedded semiconductor. This integration reduces board area and lets firmware control communications, data acquisition, timing, storage, and external equipment through dedicated peripherals. The verified manufacturer information identifies a maximum operating frequency of 180 MHz, 512 KB of Flash, 225 DMIPS, an FPU, DSP instructions, dual Quad SPI, SDRAM support, and audio interfaces. The STM32F446 family therefore fits designs where compute performance and compactness matter more than a large general-purpose package. Its BGA-style WLCSP construction also requires careful PCB layout, assembly process control, and inspection because board-level rework is less straightforward than with exposed-leaded packages. The ARM Cortex-M4 core provides deterministic control alongside accelerated floating-point and digital signal processing. This combination is useful when control loops must execute quickly alongside filtering, transforms, audio processing, or sensor-data conditioning. The 512 KB program Flash provides more local code space than many entry-level microcontrollers, although the supplied sources do not state RAM capacity, exact peripheral mappings, voltage limits, or package pin definitions. Typical uses include compact industrial control, audio processing, communications equipment, digital signal acquisition, and embedded systems that benefit from external SDRAM. The family's dual Quad SPI can support high-bandwidth serial devices, while SDRAM and audio interfaces provide expansion paths for data-intensive or multimedia designs. Firmware and board support must be selected for the exact STM32F446 device variant. The primary engineering consideration is the 81-WLCSP assembly footprint. Its 3.80 mm by 3.69 mm area supports miniaturization but demands manufacturer-qualified PCB design rules, fine-pitch assembly capability, appropriate solder-paste control, and reliable inspection. Users should download the official datasheet and package drawing before assigning signals or releasing a layout. This page consolidates verified manufacturer and distributor information, exact pricing evidence, package constraints, and engineering guidance.

STM32F446RCT6 - 180MHz 256KB Cortex-M4 MCU | STMicro

The STMicroelectronics STM32F446RCT6 is a 32-bit Arm Cortex-M4 microcontroller with DSP and FPU support, operating up to 180 MHz and packaged in a 64-LQFP 10 x 10 mm surface-mount package. It integrates 256 KB of flash memory, 128 KB of SRAM, and a 4 KB backup SRAM, making it suitable for real-time embedded systems requiring substantial local memory and peripheral integration. A microcontroller is a programmable semiconductor that combines a processor core, memory, and peripherals into one embedded-control device. The STM32F4 family belongs to the Arm Cortex-M4 microcontroller hierarchy, combining efficient interrupt-driven control with higher-performance floating-point and digital signal processing. STM32F446RCT6 is therefore positioned between simpler Cortex-M microcontrollers and higher-end Cortex-M7 devices for control, communications, and signal-processing workloads. Its headline features include a 180 MHz maximum core frequency, 256 KB flash, 128 KB system SRAM, and an Arm Cortex-M4 core with floating-point unit and DSP instructions. The verified distributor description also identifies a 64-LQFP package and high-performance foundation positioning. These resources support moderate real-time workloads, local buffering, protocol handling, and control loops without relying on external flash or SRAM. The STM32F446xC/E device family is designed for applications combining real-time control and connected embedded functionality. Its integrated processing performance supports faster control calculations than lower-frequency Cortex-M devices, while the DSP and FPU capabilities are useful for filtering, transforms, and numeric control algorithms. Exact peripheral configurations, voltage limits, timers, communication interfaces, and electrical ratings must be confirmed in the official STMicroelectronics product documentation before design release. Typical uses include industrial automation, motor and motion control, communications equipment, audio and digital signal processing, test and measurement, and connected embedded products. A motor-control design benefits from the 180 MHz processing rate and DSP/FPU resources; an industrial controller can use local memory for protocols and state; and a communications gateway can offload parsing and real-time tasks from a higher-level processor. Firmware and peripheral selection must still match the exact pinout and electrical requirements. Designers should begin with the STM32F446RC pinout and reference manual, then verify clocking, power, decoupling, reset, boot, and exposed-pin requirements against the selected PCB. Because only summary source data was supplied, detailed pin names, voltage ranges, current limits, and package thermal metrics are intentionally not guessed here. The page combines verified distributor specifications, sourcing links, and practical qualification guidance for engineering review.

STM32F446RCT6TR - 180MHz Cortex-M4 MCU 256KB Flash | ST

The STMicroelectronics STM32F446RCT6TR is a high-performance ARM Cortex-M4 32-bit RISC microcontroller operating at up to 180 MHz, integrating 256 KB of Flash memory and housed in a 64-pin LQFP (10x10 mm) package. The Cortex-M4 core includes a single-precision floating-point unit (FPU) and DSP instructions, while the on-chip Art Accelerator enables 0-wait-state execution from Flash at full CPU speed. The MCU targets motor control, industrial, audio, and consumer applications that require DSP capability with low power consumption. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, volatile and non-volatile memory, peripherals, and I/O on one silicon die. The STM32 family is built on the ARM Cortex-M architecture, a 32-bit RISC core family widely used in embedded systems for its deterministic real-time behaviour and energy efficiency. The STM32F4 sub-family is the high-performance tier, positioning the STM32F4 above Cortex-M0/M3 devices in the STM32 portfolio, with DSP extensions and an FPU that simplify the design of motor control loops, audio codecs, and signal processing pipelines. Key features of the STM32F446RCT6TR include 128 KB of SRAM, a flexible static memory controller (FSMC) for external memory expansion, multiple high-speed timers, three 12-bit ADCs (2.4 MSPS), two 12-bit DACs, USB 2.0 full-speed and high-speed OTG interfaces, CAN 2.0B, SDMMC, I2S, and I2C. The supply voltage range of 1.8 V to 3.6 V makes it suitable for battery-powered applications, and seven low-power modes (Sleep, Stop, Standby, etc.) optimise energy use in duty-cycled designs. The Cortex-M4 architecture is paired with ST's ART Accelerator, which prefetches and caches instructions to deliver linear performance from Flash, eliminating the typical wait states that limit execution throughput. Hardware divide and single-cycle multiply accumulate (MAC) operations enable real-time DSP workloads, while the memory protection unit (MPU) and true random-number generator (TRNG) support secure firmware execution and cryptographic key generation for IoT endpoints. Typical applications for the STM32F446RCT6TR include motor drives (FOC for PMSM and BLDC), industrial fieldbus nodes (CAN, RS-485), audio DSP front-ends, USB peripherals, USB-C chargers, and consumer appliances that demand 32-bit performance without an MPU-class processor. The combination of USB HS OTG, CAN, and 12-bit ADC at 2.4 MSPS positions this MCU for sensor hubs and digital power conversion in the 100 W to 1 kW range. When designing with the STM32F446RCT6TR, the VDD/VDDA pin pair must be decoupled with 100 nF and 4.7 µF capacitors placed within 5 mm of the package, and the NRST pin requires an external 10 kΩ pull-up with a 100 nF capacitor for reliable reset behaviour. Boot mode is selected through the BOOT0 pin state at reset, and designers should provide a header or test point for in-system programming via SWD (PA13/PA14). The 64-LQFP (10x10) package has a typical thermal resistance of 38 °C/W, which is adequate for industrial-grade ambient operation up to 85 °C at moderate CPU load. This page synthesises distributor pricing, drop-in pin-compatible alternatives from the same STM32F4 family, and practical PCB design notes drawn from ST application notes and reference designs, providing information beyond the manufacturer datasheet summary alone.

The verified distributor data identifies 256 KB of Flash memory and 128 KB of SRAM for this exact device, while the STM32F446xC/E family combines substantial processing performance with extensive embedded peripherals and connectivity. Its 225 DMIPS positioning makes it appropriate for responsive control, signal processing, communications, and human-interface applications where an efficient embedded MCU rather than a higher-cost MPU is required. A microcontroller is a programmable semiconductor that integrates a CPU core, memory, peripherals, and interface controllers on one chip. The STM32F446 belongs to the Arm Cortex-M4 class of 32-bit RISC embedded processors, combining deterministic real-time control with digital signal processing and single-precision floating-point capabilities. Within the broader product hierarchy, it is an MCU, then a semiconductor, then an embedded processing component designed to operate directly within a larger control or communication system. The most prominent verified features are a 180 MHz maximum core frequency, 225 DMIPS advertised for the family, 256 KB Flash, and 128 KB SRAM. The Cortex-M4 processor includes DSP and FPU resources suitable for filtering, transforms, control loops, and audio-related computations. The STM32F446 family also adds interfaces identified by STMicroelectronics, including dual Quad SPI, SDRAM capability, and audio interfaces, giving designers multiple paths for connecting sensors, displays, storage, and network or audio peripherals. As a 100-LQFP device, the STM32F446VCT7 supports a compact, widely visible surface-mount assembly while exposing substantially more I/O than smaller 48-pin or 64-pin STM32 packages. Exact peripheral assignments, pin multiplexing, voltage limits, timers, communication channels, and electrical characteristics were not supplied in the verified excerpts and must therefore be confirmed in the manufacturer datasheet before schematic or PCB signoff. The same applies to programming, debug, clock-tree, and power-supply details. Typical uses include industrial automation modules, motor and motion-control platforms, communication equipment, audio interfaces, data-acquisition systems, and connected embedded products. For a new design, use STM32CubeMX or the STM32CubeIDE ecosystem to generate startup code, configure clocks and peripherals, and organize the HAL or low-level driver layer. Validate the final operating frequency against the selected power-supply voltage and the device temperature range before deployment. The most important procurement and design checks are exact package pin compatibility, firmware-device support, memory requirements, peripheral availability, operating-temperature grade, and lifecycle continuity. Because no verified pin list was included in the supplied data, a complete 100-pin map should be taken directly from the manufacturer package documentation rather than inferred. This page consolidates verified source facts, practical integration considerations, and sourcing information while clearly separating verified values from specification gaps. For procurement, distributors list the STM32F446VCT7 from $8.3394 at LCSC as of 2026-10-22, and DigiKey and Mouser product pages provide additional availability and ordering information.

The STM32F446VET6 is positioned within STMicroelectronics’ STM32F4 family as a high-performance microcontroller for designs requiring greater processing speed and peripheral integration than basic microcontrollers. The verified distributor description identifies a 180 MHz ARM Cortex-M4 core, 512 KB Flash organized as 512K x 8, and a 100-LQFP 14 x 14 mm package. The manufacturer identifies the STM32F446xC/E devices as a family based on the high-performance Arm Cortex-M4 32-bit RISC core. The exact voltage range, RAM size, operating-temperature range, GPIO count, and detailed electrical limits were not included in the supplied source data and therefore require verification from the official datasheet before design release. This MCU is suited to applications that require deterministic embedded control and broad peripheral connectivity. Typical uses include industrial automation equipment, communications equipment, data acquisition, motor and motion-control systems, and connected embedded products. The 512 KB Flash capacity provides room for application firmware, boot code, configuration data, and protocol stacks, although actual code-size requirements must be checked against the project build. A critical design practice is to verify the complete electrical and pin-level requirements against the STMicroelectronics manufacturer datasheet before PCB layout or firmware deployment. Designers should confirm power-supply limits, clock requirements, decoupling, pin multiplexing, exposed thermal-pad behavior where applicable, programming connections, and package-specific land pattern. The distributor and manufacturer references establish the core identity and headline specifications, but they do not replace device-specific electrical validation. This page combines the supplied manufacturer and distributor information with application guidance, procurement references, comparison considerations, and engineering-oriented selection notes. Pricing and availability remain time-sensitive and should be confirmed with an authorized distributor or XAIPART at the time of quotation, especially for an active high-performance MCU.

It integrates 512 KB of Flash memory, 128 KB of SRAM, and 81 I/Os in a 100-LQFP 14 x 14 mm package. The device belongs to the STM32F4 performance-oriented microcontroller family. An Arm Cortex-M4 microcontroller combines a 32-bit RISC processor core with tightly coupled peripherals, memory, and interrupt hardware on one integrated circuit. This MCU class is designed for embedded control, real-time signal processing, communications, audio, and industrial applications. The STM32F4 family hierarchy is Cortex-M4 processor, 32-bit RISC core, embedded microcontroller, and semiconductor. Verified features for STM32F446VET6TR include an Arm Cortex-M4 core, 180 MHz maximum frequency, 512 KB Flash, 128 KB SRAM, 81 I/Os, DSP instructions, and an FPU. STMicroelectronics describes the STM32F446 family as offering 225 DMIPS and enhanced connectivity through dual Quad-SPI, SDRAM, and audio interfaces. The 100-LQFP package provides a substantial pin count for external memory, communication peripherals, and mixed-signal control systems. The STM32F446 architecture is suited to applications that need more compute performance than general-purpose Cortex-M devices without moving to a higher-complexity microcontroller architecture. Its DSP and FPU resources can accelerate filter, control, and floating-point workloads, while the 512 KB Flash and 128 KB SRAM provide local storage for firmware and working data. Exact electrical limits, peripherals, pin names, and timing values must be taken from the manufacturer datasheet before hardware release. Typical applications include industrial automation, audio and digital signal processing, communications infrastructure, motor and motion control, test and measurement, and connected embedded equipment. The 180 MHz operating rate and integrated memory make the MCU useful for real-time control tasks, while the 81 I/Os support sensors, actuators, displays, transceivers, and external peripheral devices. A key design consideration is package-level planning: the 100-LQFP footprint requires careful routing of power, ground, high-speed signals, and decoupling. Firmware compatibility also depends on exact peripheral configuration, clock setup, startup sequence, pin multiplexing, and memory initialization; a same-family or pin-compatible designation alone does not guarantee a complete firmware drop-in replacement. This product page combines verified manufacturer and distributor information with package, purchasing, comparison, and design guidance. Pricing and availability should be checked against the cited distributor listings as of 2026-10-22 before committing a production BOM.

STM32F446VET7 - 180MHz Cortex-M4 MCU with 512KB Flash | STMicroelectronics

The STMicroelectronics STM32F446VET7 is a high-performance 32-bit ARM Cortex-M4 microcontroller operating at up to 180 MHz, with 512 KB of Flash memory, 225 DMIPS, DSP instructions, and a hardware floating-point unit in a 100-LQFP 14 x 14 mm package. It also provides dual Quad SPI, SDRAM, and audio interfaces for communication and signal-processing designs. A microcontroller is a programmable embedded-system component that integrates a processor core, memory, peripherals, and I/O into one device. The STM32 MCU family belongs to the semiconductor hierarchy: microcontroller -> embedded processor -> ARM Cortex-M processor -> STM32F4 series -> STM32F446 high-performance line. This MCU combines general-purpose control with dedicated digital signal processing and hardware FPU acceleration. Verified headline features include an ARM Cortex-M4 core, 180 MHz maximum operating frequency, 225 DMIPS, and 512 KB of Flash. The integrated FPU accelerates floating-point calculations, while DSP instructions support filtering and transform workloads. Dual Quad SPI increases high-speed peripheral flexibility, and the listed SDRAM and audio interfaces make the device useful in applications that move data between memory, displays, sensors, and audio subsystems. The STM32F446VET7 is positioned for industrial embedded control, high-speed communication, data acquisition, audio processing, and embedded user-interface systems. Its 100-LQFP package exposes substantially more I/O than small 32- or 64-pin packages, which helps when a design needs multiple buses, control signals, and communications peripherals. The available 512 KB Flash also provides room for application code, firmware, and boot logic without requiring the largest STM32F4 memory configuration. Designers should verify voltage, memory, peripheral, pin, timing, and thermal details against the manufacturer datasheet before layout. In particular, mixed-signal, SDRAM, and high-speed communication designs require disciplined pin multiplexing, controlled impedance routing, decoupling, and grounding. Firmware replacement should also be validated because bootloader behavior, peripheral configuration, clock limits, and application code compatibility can vary even when the package is unchanged. This page combines verified manufacturer and distributor facts with application guidance, package selection, sourcing information, and drop-in alternatives. Because the retrieved data does not include the complete electrical tables or a verified pin-to-pin substitute matrix, unavailable values remain marked for validation rather than being inferred.
