Product details
Overview
STM32F746ZGT6E from STMicroelectronics is a high-performance ARM Cortex-M7 microcontroller with FPU, 216 MHz max clock, 1 MB Flash, 320+16+4 KB RAM, integrated LCD-TFT controller, dual CAN, USB OTG HS/FS, and 10/100 Ethernet MAC. It serves as the main application processor in industrial HMI, medical imaging front-ends, and networked embedded gateways requiring real-time graphics and connectivity.
For engineers reviewing the STM32F746ZGT6E datasheet, STM32F746ZGT6E pinout, STM32F746ZGT6E application, or STM32F746ZGT6E equivalent, key selection criteria include LQFP144 package compatibility, 216 MHz Cortex-M7 performance with ART Accelerator™, dual-bank Flash for seamless firmware updates, Chrom-ART Accelerator™ for GUI rendering, and IEEE 1588v2 support in the Ethernet MAC.
Technical Context
The device implements a tightly coupled Arm Cortex-M7 core with 4 KB instruction and 4 KB data L1 caches plus Adaptive Real-Time Accelerator™ (ART) for zero-wait-state execution from Flash. It integrates dual-mode Quad-SPI, parallel DCMI (54 MB/s), and LTDC supporting XGA resolution with hardware alpha blending.
Its memory subsystem includes 320 KB SRAM (64 KB DTCM + 16 KB ITCM + 4 KB backup), flexible external memory controller (FMC) for SDRAM/NOR/NAND, and dual 12-bit DACs with configurable output buffers. Clock architecture features three PLLs (main, audio, SAI) enabling independent domain timing for audio, display, and system clocks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VIT6 | Higher clock (480 MHz), dual-core (Cortex-M7 + M4), 2 MB Flash, no built-in LCD-TFT controller | Better for compute-intensive tasks (e.g., AI inference), but requires external display controller | Select when raw processing throughput outweighs integrated graphics needs. |
| STM32F767ZGT6 | Same package and pinout; adds crypto accelerator (AES, HASH, RNG), no Ethernet MAC | Suitable for secure IoT edge nodes where encryption is critical but wired Ethernet is not required | Choose for TLS-secured OTA updates and data-at-rest protection in battery-powered gateways. |
Compared with STM32F746ZGT6E, the STM32H743VIT6 offers higher computational headroom but sacrifices integrated display capability, while the STM32F767ZGT6 trades Ethernet for cryptographic acceleration-making each optimal only when their distinguishing feature aligns with system-level priorities.
