Product details
Overview
STM32F746VGT7 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, Ethernet MAC, USB OTG HS/FS, and dual CAN interfaces - deployed in industrial HMI, medical imaging front-ends, and networked edge gateways requiring deterministic real-time graphics and connectivity.
For engineers reviewing the STM32F746VGT7 datasheet, STM32F746VGT7 pinout, STM32F746VGT7 application, or STM32F746VGT7 equivalent, key selection considerations include LQFP100 package compatibility, TCM RAM allocation for latency-critical firmware, ART Accelerator™ cache behavior, and dual-CAN + Ethernet coexistence in time-sensitive control networks.
Technical Context
The STM32F746VGT7 implements an Arm Cortex-M7 core with tightly coupled memory (TCM) architecture: 64 KB data TCM RAM for real-time data buffers and 16 KB instruction TCM RAM for critical ISR routines, both accessible at zero wait states. Its ART Accelerator™ enables full-speed execution from Flash via 4 KB instruction and 4 KB data caches.
It integrates dual-mode Quad-SPI for XIP and memory-mapped external flash, a Chrom-ART Accelerator™ (DMA2D) for hardware-accelerated 2D graphics composition, and IEEE 1588v2-compliant Ethernet MAC with dedicated DMA - enabling synchronized multi-node industrial control without external timing ICs.

Pinout & Package
LQFP100 (14 × 14 mm, 0.5 mm pitch) package with exposed thermal pad; 100-pin quad flat configuration optimized for high I/O count and thermal dissipation in compact industrial PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD/VSS | Core power supply / ground | 1.7–3.6 V operation; multiple pairs ensure low-noise analog/digital separation and stable core voltage under dynamic load |
| VCAP1/VCAP2 | Internal regulator decoupling | Requires 2.2 µF ceramic capacitors per pin to stabilize 1.2 V internal core voltage; mandatory for reliable 216 MHz operation |

Key Features
| Feature | Design Value |
|---|---|
| ART Accelerator™ + L1 cache | Enables zero-wait-state execution from Flash at 216 MHz, eliminating external SDRAM dependency for most real-time applications |
| Chrom-ART Accelerator™ (DMA2D) | Offloads CPU from pixel blending, image rotation, and alpha-blending operations - cuts GUI rendering latency by >70% vs software-only |
| Dual CAN 2.0B controllers | Supports concurrent CAN FD and classical CAN traffic on separate buses; essential for automotive diagnostics + chassis control segregation |
| Flexible Memory Controller (FMC) | Direct interface to NOR/NAND/PSRAM/SDRAM; enables expansion beyond internal RAM for large buffer or firmware update storage |
| IEEE 1588v2 Ethernet MAC | Hardware timestamping with sub-100 ns precision enables deterministic synchronization across distributed PLCs or motion controllers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance Cortex-M7 MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VIT6 | Higher clock (480 MHz), dual-core (Cortex-M7 + M4), 2 MB Flash, no integrated LCD-TFT controller | Targeted at compute-intensive AI inference or dual-role secure boot + application execution; lacks native display interface | Select when raw processing throughput or asymmetric dual-core partitioning outweighs need for integrated graphics acceleration |
| STM32F767ZIT6 | Same Cortex-M7 core, 2 MB Flash, 512 KB RAM, LQFP144 package (144 pins), adds SDMMC v2.0 and enhanced crypto | Used where larger code footprint, more GPIOs, or SD card-based firmware updates are required; same LCD-TFT capability | Select when board layout allows LQFP144 and additional Flash/RAM headroom justifies extra cost and size |
Compared with STM32F746VGT7, the STM32H743VIT6 delivers higher computational density but requires external display controller, while the STM32F767ZIT6 extends memory and I/O without changing graphics or real-time architecture - making it a drop-in upgrade path for existing F746 designs needing scale.

FAQ
What is the maximum operating temperature range for STM32F746VGT7?
The STM32F746VGT7 is rated for industrial temperature range: –40 °C to +85 °C ambient. Its thermal design supports continuous 216 MHz operation within this range when using recommended VCAP decoupling and PCB copper pour under the exposed thermal pad per ST AN4828 guidelines.
Does STM32F746VGT7 support hardware encryption acceleration?
No, the STM32F746VGT7 does not include dedicated cryptographic accelerators (AES, SHA, PKA). It relies on software libraries (e.g., mbed TLS) or external secure elements. For hardware crypto, ST recommends STM32H7 or STM32L5 series devices with CryptoCell-310 or AES-256 engines.
Can the LCD-TFT controller drive RGB888 format at 1024×768 resolution?
Yes - the integrated LCD-TFT controller supports RGB888 (24-bit) pixel format at XGA resolution (1024×768) with programmable polarity, HSYNC/VSYNC timing, and dotclock up to 65 MHz. It requires external LVDS or RGB panel interface; no external timing controller is needed.
Is the USB OTG HS interface compatible with ULPI physical layer?
Yes - the USB OTG HS interface includes built-in ULPI transceiver support. It accepts standard 60 MHz ULPI signals (D0–D7, CLK, DIR, NXT, STP) and integrates dedicated DMA for zero-copy high-speed transfers, enabling 480 Mbps operation without external PHY.
