Overview

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.
