Product details
Overview
STM32F767IGK6 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, featuring 2 MB flash (dual-bank), 512 KB SRAM (including 128 KB data TCM), USB OTG HS/FS, Ethernet MAC, LCD-TFT controller, and MIPI DSI host-used in industrial HMI, medical imaging front-ends, and real-time motor control systems.
For engineers reviewing the STM32F767IGK6 datasheet, STM32F767IGK6 pinout, STM32F767IGK6 application, or STM32F767IGK6 equivalent, key selection considerations include dual-bank flash for safe firmware updates, 168 I/Os with 5 V tolerance, hardware JPEG codec for embedded vision, and IEEE 1588v2 support for deterministic industrial networking.
Technical Context
The STM32F767IGK6 integrates an Arm Cortex-M7 core with ART Accelerator and dual 16 KB L1 caches (I/D), enabling zero-wait-state execution from flash or external memory. Its AXI-AHB bus matrix supports concurrent high-bandwidth access across CPU, DMA, and peripherals including FMC, QSPI, and Ethernet MAC.
It implements three independent CAN 2.0B controllers, dual USB OTG (FS + HS with dedicated DMA), and a full-featured graphics subsystem comprising LTDC, Chrom-ART Accelerator (DMA2D), and hardware JPEG codec-enabling direct drive of XGA displays and accelerated GUI rendering without external GPU.

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, but no built-in DSI host or JPEG codec. | Better for asymmetric multiprocessing or ultra-low-latency control; lacks native display compression acceleration. | Select when needing >400 MHz compute headroom and dual-core isolation, not display-centric workloads. |
| STM32F769IIK6 | Same core/peripherals but in BGA216 package with enhanced crypto (AES-256, PKA), no LCD-TFT controller, adds MIPI DSI only. | Optimized for secure IoT gateways with display output but no parallel RGB interface. | Choose for security-critical connected devices where cryptographic acceleration and compact BGA are prioritized over XGA parallel display support. |
Compared with STM32F767IGK6, the STM32H743VIT6 offers higher compute throughput but requires external JPEG IP and lacks integrated XGA LCD controller; the STM32F769IIK6 trades parallel display capability for advanced security features and smaller footprint-making the IGK6 optimal for cost-sensitive, display-rich industrial HMIs.

FAQ
What is the maximum operating frequency and how is it achieved?
The STM32F767IGK6 achieves 216 MHz maximum CPU frequency using its Arm Cortex-M7 core with ART Accelerator and dual 16 KB L1 caches. Stable operation requires proper decoupling of VCAP1/VCAP2 pins with 2.2 µF ceramic capacitors and adherence to voltage regulator ON mode timing during startup per Section 6.3.3 of DS11532 Rev 9.
Does STM32F767IGK6 support hardware encryption?
No, the STM32F767IGK6 does not integrate hardware cryptographic accelerators (e.g., AES, PKA, or HASH). It relies on software libraries or external secure elements. For hardware crypto, consider STM32F769xx or STM32H7xx families, which include AES-256, PKA, and TRNG with entropy certification.
Can the LQFP176 package be used for high-speed USB OTG HS operation?
Yes-the LQFP176 package supports USB OTG HS via ULPI interface (pins PA3, PB0–PB5, PC0). Signal integrity requires strict PCB layout: controlled 30 Ω differential impedance for ULPI traces, minimized stub length (<5 mm), and separation from noisy digital nets per AN4879 guidelines.
What display interfaces are supported and what resolutions?
The STM32F767IGK6 supports parallel RGB (LCD-TFT controller up to XGA/1024×768) and MIPI DSI (host controller up to 720p@30 Hz). It does not support HDMI or LVDS natively. Dual-display operation is possible using LTDC + DSIHOST simultaneously, with DMA2D enabling layer composition between sources.
