STMicroelectronics STM32F767IIK6

Overview

STM32F767IIK6 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, featuring 2 MB dual-bank flash, 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 STM32F767IIK6 datasheet, STM32F767IIK6 pinout, STM32F767IIK6 application, or STM32F767IIK6 equivalent, key selection criteria include dual-bank flash read-while-write capability, 168 I/Os with 108 MHz toggle rate, hardware JPEG codec, Chrom-ART Accelerator (DMA2D), and IEEE 1588v2 Ethernet support for deterministic networking.

Technical Context

The STM32F767IIK6 integrates an Arm Cortex-M7 core with ART Accelerator and 16 KB I/D cache enabling zero-wait-state execution from flash or external memory; its AXI-AHB bus matrix supports concurrent high-bandwidth access to flash, SRAM, and peripherals including FMC, QSPI, and Ethernet MAC.

It implements three independent clock domains: main system clock (up to 216 MHz), audio/LCD PLLs (PLLI2S/PLLSAI), and DSI PHY PLL; features include dual-mode Quad-SPI, DFSDM for sigma-delta sensor interfacing, and hardware-accelerated cryptographic primitives via RNG and CRC units.

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32F767IIK6 operates at up to 216 MHz using its internal voltage regulator and ART Accelerator with 16 KB I/D cache. This frequency is sustained only when executing from flash with prefetch and L1-cache enabled; external clock sources must be ≥4 MHz and ≤26 MHz, and VCAP1/VCAP2 capacitors (2.2 µF) must be correctly placed per datasheet Section 6.3.2.

Does STM32F767IIK6 support hardware encryption or secure boot?

The STM32F767IIK6 includes a true random number generator (RNG) and CRC calculation unit but lacks dedicated AES, PKA, or secure boot ROM. Secure firmware validation requires external trusted execution environment or software-based signature verification; for certified security, consider STM32F769xx or STM32H7 series with embedded crypto accelerators.

Can the LCD-TFT controller drive a 1080p display?

No-the integrated LCD-TFT controller supports up to XGA resolution (1024×768); 1080p (1920×1080) exceeds its pixel clock and memory bandwidth limits. For Full HD, use the MIPI DSI host interface with an external DSI-to-LVDS bridge IC or select STM32F769xx with HDMI-CEC and higher bandwidth peripheral routing.

What debug interfaces are supported and what trace capability exists?

The STM32F767IIK6 supports SWD and JTAG interfaces for programming and debugging, plus Cortex-M7 Trace Macrocell™ (ETM) for instruction-level trace. ETM requires external trace port analyzer (e.g., ARM CoreSight) and consumes dedicated pins (TRACED0–TRACED3, TRACECLK); trace depth depends on external buffer size and clock domain alignment.
