Product details
Overview
STM32F746IGK6 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 (XGA), dual CAN 2.0B, USB OTG HS/FS, and 10/100 Ethernet MAC - deployed in industrial HMI, medical imaging front-ends, and networked edge gateways.
For engineers reviewing the STM32F746IGK6 datasheet, STM32F746IGK6 pinout, STM32F746IGK6 application, or STM32F746IGK6 equivalent, key selection criteria include TCM RAM allocation for real-time control loops, Chrom-ART Accelerator™ support for GUI rendering, IEEE 1588v2 hardware timestamping in Ethernet, and dual-mode Quad-SPI for secure firmware update storage.
Technical Context
The STM32F746IGK6 implements a tightly coupled Arm Cortex-M7 core with 4 KB instruction and 4 KB data L1 cache plus ART Accelerator™ enabling zero-wait-state execution from Flash or external memory. It integrates dual-bank Flash with read-while-write capability and supports boot from internal Flash, system memory, or external interfaces via flexible remapping.
Its peripheral subsystem includes a dedicated AXI-AHB bus matrix for concurrent high-bandwidth access to SRAM, FMC, and DMA2D; the LCD-TFT controller (LTDC) drives up to XGA (1024×768) displays with alpha blending and layer composition; and the dual CAN controllers operate independently with full CAN 2.0B protocol compliance and message filtering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VIK6 | Higher clock (480 MHz), dual-core (Cortex-M7 + M4), 2 MB Flash, no built-in LCD-TFT controller | Targeted at compute-intensive tasks (e.g., AI inference) where display is handled externally or omitted | Select when >216 MHz performance or dual-core isolation is required; avoid if XGA display integration is mandatory |
| STM32F767IGK6 | Same Cortex-M7 core, identical peripherals, but adds FMC NAND interface and enhanced crypto (AES-256, SHA-256, PKA) | Suitable for secure firmware update and encrypted data logging in regulated environments | Select when NAND boot support or hardware crypto acceleration is required; otherwise identical functional fit |
Compared with STM32F746IGK6, STM32H743VIK6 delivers higher compute throughput but lacks integrated display control, while STM32F767IGK6 extends security and storage capabilities without altering core timing or graphics architecture - making it a drop-in upgrade for certified systems needing stronger trust anchors.

FAQ
What is the maximum operating temperature range for STM32F746IGK6?
The STM32F746IGK6 is rated for industrial temperature range: –40 °C to +85 °C ambient, validated per datasheet Section 6.3.1. Thermal derating applies above 70 °C ambient when operating at maximum frequency and full peripheral load; junction temperature must remain below 125 °C per absolute maximum ratings.
Does STM32F746IGK6 support external SDRAM, and what is the maximum bandwidth?
Yes - the Flexible Memory Controller (FMC) supports SDRAM up to 16 MB with 16-bit data bus and 13-row/10-column addressing. Maximum theoretical bandwidth is 133 MB/s (16-bit × 8.33 MHz clock), confirmed by timing parameters in Section 6.3.27 of DS10916 Rev 5.
Can the Chrom-ART Accelerator™ perform alpha blending between two video layers?
Yes - the Chrom-ART Accelerator™ (DMA2D) supports dual-layer alpha blending with programmable opacity (0–255) per pixel, enabling overlay of GUI elements on live camera feed or video stream. This is implemented via the Layer 1/Layer 2 composition engine with configurable color keying and blending coefficients.
Is USB HS operation possible without an external PHY, and what interface does it use?
No - USB High-Speed (480 Mbps) requires an external ULPI PHY. The STM32F746IGK6 provides an 8-bit ULPI interface (PB14–PB15 + PB5) and dedicated USB HS DMA channel, but no on-chip HS transceiver. Full-speed (12 Mbps) is supported natively via PA11/PA12 with integrated PHY.
