STM32F446VET6 - 180MHz Cortex-M4 512KB MCU | STMicroelectronics
MPN: STM32F446VET6 ✓ Hoạt độngSTM32F446VET6 Tóm tắt
An ARM Cortex-M4 microcontroller is a 32-bit embedded processor designed for real-time control workloads. Its architecture belongs to the MCU hierarchy, combining a processor core, memory, communication peripherals, timers, analog interfaces, and interrupt handling on one integrated circuit. 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.

Ứng dụng tiêu biểu
STM32F446VET6 phù hợp cho 6 Áp dụngs: Industrial Automation Controller, Connected Embedded Sensor Node, Data Acquisition and Signal Processing, Communications Gateway, Motor and Motion Control, Consumer and Embedded Control Product.
Industrial Automation Controller
The STM32F446VET6 fits industrial automation controllers that need a fast 180 MHz Arm Cortex-M4 core, 512 KB of Flash, and a 100-pin LQFP interface for sensors, actuators, and communications. Its real-time processing capability can support control loops, state machines, diagnostics, and protocol handling in one device. The 512 KB Flash budget should be checked against the application image, bootloader, and update mechanism, while the final peripheral assignments must be verified against the datasheet.
Được đề xuất
Connected Embedded Sensor Node
STM32F446VET6 is suitable for a connected sensor node that combines local sampling, digital filtering, and network protocol handling. Its 180 MHz Cortex-M4 core provides processing headroom for signal conditioning and application logic, while 512 KB Flash provides storage for firmware and configuration data. The design must still verify the required ADC, timer, communication peripherals, power rails, and pin multiplexing from the official device documentation.
Được đề xuất
Data Acquisition and Signal Processing
The STM32F446VET6 can serve as the control processor in a data-acquisition system where sampled data must be filtered, buffered, and transferred. The Arm Cortex-M4 DSP and FPU features identified in the supplied distributor information are useful for arithmetic-heavy processing, and the 180 MHz clock rate supports real-time control tasks. Exact ADC resolution, sampling rate, timer channels, DMA behavior, and memory bandwidth are not provided in the supplied data and require datasheet validation.
Được đề xuất
Communications Gateway
STM32F446VET6 is appropriate for a communications gateway that must manage several serial interfaces, local protocol conversion, and real-time routing logic. Its 180 MHz Cortex-M4 core and 512 KB Flash provide a useful combination for embedded protocol stacks and control firmware, while the LQFP-100 package offers a larger pin count than smaller MCUs. Verify the required USART, SPI, I2C, USB, CAN, Ethernet, and DMA resources before assigning pins.
Được đề xuất
Motor and Motion Control
The 180 MHz Arm Cortex-M4 processing capability of STM32F446VET6 is useful in motor-control and motion-control systems that combine fast control-loop execution with supervisory logic. The MCU can coordinate timers, feedback signals, communications, and protection handling, subject to the exact peripheral resources of the STM32F446xE device. Power-stage design, isolation, current sensing, thermal protection, and safety timing must be designed and validated independently.
Được đề xuất
Consumer and Embedded Control Product
STM32F446VET6 can be used in compact embedded products that need more processing capability than a basic MCU while retaining a conventional surface-mount LQFP assembly flow. Its 180 MHz Cortex-M4 core supports responsive user-interface logic, peripheral orchestration, and embedded communications, while the 512 KB Flash supports a moderately sized application. Validate EMC, power consumption, boot security, programming access, and thermal performance for the final enclosure and use environment.

Ghi chú thiết kế
Verify the exact STM32F446xE supply-voltage range, internal regulator requirements, power-up sequence, decoupling values, and current limits in the official STMicroelectronics datasheet before routing the PCB. Do not infer the power architecture from the distributor headline specifications. Place required bulk and local decoupling close to the relevant supply pins, and validate startup, reset, brownout, and shutdown behavior over the complete temperature range.
Use the official STMicroelectronics LQFP-100 package drawing and pinout rather than relying on generic 100-pin symbols. Preserve the package orientation, pin-1 marker, exposed thermal and ground connections, and recommended land pattern. Confirm every alternate-function pin and debug connection against the device reference manual before fab release; package fit alone does not establish functional compatibility.
For high-speed external interfaces or clocked peripherals, keep traces short, provide continuous return paths, and separate noisy switching paths from sensitive analog or measurement inputs. Verify external component values and signal timing against the peripheral specifications in the manufacturer datasheet. Do not assume that the 180 MHz core frequency directly permits 180 MHz signal rates on every interface.
The supplied web results identify STM32F407VET6, STM32F446RET6, and STM32F429VIT6 as related devices, but they do not prove complete drop-in equivalence. Before substitution, compare pin names, alternate functions, power pins, clock pins, reset and debug pins, peripheral mapping, memory configuration, electrical limits, package drawings, and firmware support. Also verify that the Flash size matches the linker configuration.
