概述

Description

STM32F446ZET7 is a mid/high-end MCU from ST’s STM32F4 family. It uses a 32-bit ARM Cortex-M4F core with a floating-point unit and DSP instructions, running up to 180 MHz. It is offered in a 100-pin LQFP package (ZET) and typically provides up to 512 KB of Flash memory and 128 KB of RAM.
Key peripherals include USB Full-Speed OTG, CAN, multiple SPI/I2C/UART serial interfaces, several timers (PWM capable), a 12-bit ADC (up to multiple channels) and dual 12-bit DACs, plus a DMA controller. It supports 3.3V I/O and various power modes for low-power applications.
Development is well-supported by ST’s ecosystem (HAL/LL drivers, STM32CubeMX), with toolchains like GCC, Keil, and IAR. Applications: motor control, audio, USB devices, embedded HMI, and other embedded systems requiring higher performance than basic MCUs.

Features

Key features of STM32F446ZET7 (STM32F4 family):
- CPU: 32‑bit ARM Cortex‑M4F with single‑precision FPU and DSP instructions
- Speed: Up to 180 MHz operation
- Memory (variant dependent): up to 512 KB Flash, up to 128 KB RAM
- DMA: multi‑channel Direct Memory Access controller
- Timers: advanced‑control, general‑purpose and basic timers with PWM
- USB: USB OTG Full‑Speed
- Connectivity: CAN, SDIO, I2C (multiple buses), SPI/I2S, USART/UART
- Analog: 12‑bit ADC (up to multiple channels, high sample rate); 12‑bit DAC (availability depends on package)
- Security/Debug: MPU, SWD/JTAG for debugging
- Other: CRC engine for data integrity; ART accelerator for Flash access; multiple power modes and wide operating voltage
- Operating range: typical industrial temperature range (-40°C to 85°C) and 1.7–3.6 V supply (varies by package)
Note: exact Flash/RAM counts and peripheral availability can vary by package/pinout within the F446Z family.
