Product details
Overview
NUCLEO-F446ZE from STMicroelectronics is an STM32 Nucleo-144 development board built around the STM32F446ZET6 microcontroller (ARM Cortex-M4F, 180 MHz, 512 KB Flash, 128 KB RAM, LQFP144). It integrates ST-LINK/V2-1 debugger/programmer, ST Zio and Arduino Uno V3 expansion connectors, USB Micro-AB for USB OTG Full Speed, and supports STM32Cube ecosystem for rapid prototyping of motor control, industrial I/O, and USB-connected embedded systems.
For engineers reviewing the NUCLEO-F446ZE datasheet, NUCLEO-F446ZE pinout, NUCLEO-F446ZE application, or NUCLEO-F446ZE equivalent, this board delivers verified hardware compatibility with STM32CubeMX configuration, real-time debugging via Virtual COM port and mass storage mode, and out-of-box support for FreeRTOS, USB device stacks, and HAL-based peripheral drivers - critical for validating firmware on production-targeted LQFP144-packaged F4-series MCUs.
Technical Context
The NUCLEO-F446ZE implements a complete evaluation platform for the STM32F446ZET6, which features a single-precision FPU, ART Accelerator™ for zero-wait-state execution from Flash, and advanced analog peripherals including dual 12-bit ADCs (2.4 MSPS), two 12-bit DACs, and flexible digital filters (DFSDM). Its clock tree supports multiple PLL configurations, including dedicated audio PLL for I²S and SPDIF interfaces.
Board-level design includes a 32.768 kHz crystal for RTC operation, three user LEDs (LD1–LD3), two push-buttons (user + reset), and dual power options: USB VBUS or external 7–12 V supply. The ST-LINK/V2-1 subsystem provides SWD debugging, firmware flashing, and serial communication without requiring external tools.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Target MCU | STM32F446ZET6: ARM Cortex-M4F @ 180 MHz, 512 KB Flash, 128 KB SRAM, LQFP144 package - enables complex real-time control with floating-point math and large firmware footprint. |
| Debug Interface | Integrated ST-LINK/V2-1: Provides SWD debugging, USB-powered virtual COM port, and mass storage programming - eliminates need for external JTAG/SWD probe. |
| Expansion Connectors | ST Zio + Arduino Uno V3 headers: Expose all MCU GPIOs, ADCs, timers, and communication peripherals (SPI/I²C/UART) for shield compatibility and hardware extension. |
| USB Interface | USB Micro-AB connector supporting USB OTG Full Speed: Enables device-mode USB HID, CDC, MSC, and host-capable peripheral enumeration - validated with STM32 USB Device Library. |
| Power Options | Flexible sourcing: USB VBUS (5 V), external 7–12 V DC input, or ST-LINK USB power - supports both bench testing and field-deployable prototype validation. |
| On-board Peripherals | 32.768 kHz RTC crystal, 3 user LEDs, 2 tactile buttons (user + reset): Provides immediate visual feedback and timekeeping reference for low-power and real-time scheduling tests. |

Manufacturer
STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, designing and manufacturing microcontrollers, power management ICs, sensors, and analog components for automotive, industrial, and consumer applications.
The STM32 Nucleo series was developed to accelerate embedded software development by delivering standardized, open-hardware evaluation platforms tightly integrated with STM32Cube software stack - enabling seamless transition from prototype to production across the STM32 portfolio.
FAQ
Does NUCLEO-F446ZE support USB Host functionality?
No. The board implements USB OTG Full Speed in device-only mode via the Micro-AB connector, as confirmed by its STM32F446ZET6 configuration and ST's official documentation. Host capability requires external PHY or alternate hardware not present on this board.
Can the on-board ST-LINK/V2-1 program external STM32 targets?
Yes. The ST-LINK/V2-1 can be used as an external debugger by disconnecting the SB12/SB13 solder bridges and connecting SWDIO/SWCLK/TX/RX pins to another STM32 board - enabling firmware programming and real-time debugging of external LQFP144 or QFP64 targets.
What is the maximum operating frequency of the STM32F446ZET6 on this board?
The MCU runs at its rated maximum of 180 MHz using the internal PLL driven by the 8 MHz HSE oscillator. This frequency is fully supported by the board's power delivery and clock circuitry, and verified in STM32CubeMX-generated startup code and reference examples.
Is Ethernet supported on NUCLEO-F446ZE?
No. Ethernet PHY and RMII/MII interface are absent - unlike NUCLEO-F429ZI or NUCLEO-F746ZG variants. The F446ZE MCU lacks embedded Ethernet MAC, and the board omits external PHY, magnetics, and RJ45 connector per ST's official ordering table and schematic documentation.
