Product details
Overview
STM32F746VEH6 from STMicroelectronics is a high-performance ARM Cortex-M7 microcontroller with FPU, 216 MHz max CPU frequency, 512 KB Flash, 320+16+4 KB RAM, integrated LCD-TFT controller (XGA), dual CAN 2.0B, USB OTG HS/FS, and 10/100 Ethernet MAC - deployed in industrial HMI, medical imaging front-ends, and real-time motor control systems.
For engineers reviewing the STM32F746VEH6 datasheet, STM32F746VEH6 pinout, STM32F746VEH6 application, or STM32F746VEH6 equivalent, key selection considerations include TCM RAM allocation for deterministic code execution, Chrom-ART Accelerator™ support for GUI rendering offload, dual-CAN redundancy for automotive diagnostics, and IEEE 1588v2 hardware timestamping for synchronized industrial networking.
Technical Context
The STM32F746VEH6 implements an Arm Cortex-M7 core with L1 instruction/data caches (4 KB each), ART Accelerator™ enabling zero-wait-state execution from Flash, and MPU for memory protection. It integrates dual-bank Flash with read-while-write capability and supports external memory via Flexible Memory Controller (FMC) for SDRAM/NOR/NAND.
Its connectivity stack includes two independent USB controllers (OTG_FS + OTG_HS with dedicated DMA), 10/100 Ethernet MAC with IEEE 1588v2 hardware support, and dual CAN 2.0B interfaces. The peripheral set features three 12-bit ADCs (7.2 MSPS triple-interleaved), two 12-bit DACs, and parallel camera interface (DCMI) up to 54 MB/s.
Key Specifications

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 | Targeted at AI edge inference + real-time control co-processing; lacks integrated display engine | Select when needing >400 DMIPS and heterogeneous compute, but requires external GPU or display bridge IC. |
| STM32F767ZIT6 | Same Cortex-M7 core, 2 MB Flash, 512 KB RAM, identical peripheral set except no Chrom-ART Accelerator™ | Offers larger memory for complex firmware but lacks hardware-accelerated 2D graphics rendering | Choose when GUI complexity is low or software-rendered UI suffices, and extended Flash is prioritized over display acceleration. |
Compared with STM32F746VEH6, the STM32H743VIT6 delivers higher computational throughput but requires external display interface logic, while the STM32F767ZIT6 trades Chrom-ART offloading for expanded memory - making STM32F746VEH6 optimal for cost-sensitive, display-integrated real-time systems.

FAQ
What is the maximum operating temperature range for STM32F746VEH6?
The STM32F746VEH6 is rated for industrial temperature range: –40 °C to +85 °C ambient. Its thermal design supports continuous operation at full 216 MHz clock under natural convection with proper PCB copper pour on VSS/VDD planes and thermal pad soldering per ST's AN4879 guidelines.
Does STM32F746VEH6 support secure boot and cryptographic acceleration?
Yes - it includes hardware AES-128/192/256, SHA-1/SHA-224/SHA-256, and RSA-2048 acceleration engines. Secure boot is implemented via embedded ROM bootloader with public-key signature verification and Flash read-out protection (RDP level 1/2).
Can the LCD-TFT controller drive RGB888 displays?
No - the integrated LTDC supports only RGB565, RGB666, and RGB888 *with dithering* (not native 24-bit). True RGB888 output requires external LVDS or MIPI-DSI bridge ICs; the controller's pixel clock max is 65 MHz, limiting native resolution to XGA (1024×768) at 60 Hz.
Is the USB OTG HS interface compliant with USB 2.0 High-Speed signaling?
Yes - the OTG_HS peripheral includes a ULPI interface and on-chip full-speed PHY, enabling true 480 Mbps High-Speed operation when paired with an external ULPI transceiver. It supports host/device/OTG roles and battery charging detection (BC 1.2).
