Overview

The STM32F446ZET6 is a high-performance 32-bit microcontroller featuring an Arm Cortex-M4 core with a Floating Point Unit (FPU) operating at speeds up to 180MHz. It integrates 512KB of Flash memory and 128KB of SRAM, leveraging the Adaptive Real-Time (ART) accelerator to achieve 0-wait state execution from Flash memory. This device provides a significant balance of processing power, power efficiency, and a rich set of peripherals in a 144-pin LQFP package.

Why Choose This Part

The ART Accelerator and 180MHz clock provide high computational throughput for real-time applications. Engineers benefit from a vast array of connectivity options, including QuadSPI for memory expansion and a flexible external memory controller for SRAM, PSRAM, or NOR Flash. Its wide supply voltage range of 1.7V to 3.6V and multiple low-power modes assist in managing thermal and power budgets in dense designs.

Applications

High-End Motor Control
Utilizes advanced timers and FPU for precision three-phase motor control algorithms.
Industrial Communications Gateway
Bridges multiple protocols using dual CAN interfaces, USB OTG, and extensive serial peripherals.
Consumer Audio Processing
Leverages dedicated SPDIF-Rx, I2S, and SAI interfaces for digital audio streaming and processing.
Human Machine Interface (HMI)
Drives parallel LCD interfaces (8080/6800 modes) and handles complex GUI logic with the 180MHz core.
