Overview

The STM32F746ZGT6 is a high-performance 32-bit microcontroller based on the Arm Cortex-M7 core operating at up to 216 MHz. It features 1 MB of Flash memory and 320 KB of RAM, integrating specialized hardware acceleration for graphics and efficient memory access including the Chrom-ART Accelerator and L1-cache.

Why Choose This Part

The Cortex-M7 core with its 4 KB data and instruction caches provides significantly higher compute throughput than Cortex-M4 designs. Its extensive connectivity suite, including Ethernet and high-speed USB OTG, paired with 114 I/Os in a 144-LQFP package, offers maximum system flexibility.

Applications

Human-Machine Interface (HMI)
Utilizes the integrated LCD-TFT controller and Chrom-ART Accelerator to drive sophisticated graphical user interfaces with low CPU overhead.
Industrial Gateway
Leverages Ethernet, dual CANbus, and multiple UART/SPI interfaces to bridge industrial fieldbus protocols to IT networks.
Digital Audio Processing
Employs the FPU, DSP instructions, and dedicated SAI and SPDIF-Rx interfaces for high-fidelity audio stream processing and distribution.
Smart Factory Automation
Acts as a central controller for complex machinery requiring high-speed I/O, motor control PWMs, and 12-bit ADC data acquisition.
