Product details
Overview
STM32F765IIK7 from STMicroelectronics is an Arm® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, 2 MB flash (dual-bank), 512 KB SRAM (including 128 KB data TCM), and integrated LCD-TFT + MIPI DSI controllers for embedded graphics. It supports USB OTG HS/FS, 3×CAN 2.0B, 10/100 Ethernet MAC with IEEE 1588v2, and hardware JPEG codec - deployed in industrial HMI, medical imaging front-ends, and networked edge gateways.
For engineers reviewing the STM32F765IIK7 datasheet, STM32F765IIK7 pinout, STM32F765IIK7 application, or STM32F765IIK7 equivalent, key selection criteria include dual-bank flash read-while-write capability, 168 I/Os with 108 MHz toggle rate, 3×12-bit 2.4 MSPS ADCs, hardware-accelerated 2D graphics (DMA2D), and MIPI D-PHY compliance for display interface design.
Technical Context
The device implements a tightly coupled memory architecture with 16 KB I/D L1 cache and ART Accelerator enabling zero-wait-state execution from flash or external memories. Its AXI-AHB bus matrix supports concurrent high-bandwidth access to flash, SRAM, FMC, and peripherals including dual-mode Quad-SPI and SDMMC.
Real-time performance is enhanced by dedicated instruction/data TCM RAM (16 KB + 128 KB), low-power timer (LPTIM1) operational in Stop mode, and hardware crypto acceleration via RNG and CRC units. The DSI host controller complies with MIPI D-PHY v1.2 and supports up to 720p@30 Hz with embedded PLL and regulator.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance ARM Cortex-M7 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F767ZIT6 | LQFP144 package (20×20 mm); same core/peripherals but no DSI host; LCD-TFT only | Suitable for cost-sensitive HMI designs using parallel RGB displays instead of MIPI DSI panels | Select when DSI interface is unnecessary and PCB space constraints favor smaller footprint |
| STM32H743VIT6 | Cortex-M7 @ 480 MHz, 2 MB flash, 1 MB RAM, dual-core (M7+M4), no DSI host, higher power consumption | Better for compute-intensive tasks (e.g., AI inference) where dual-core coordination outweighs display integration needs | Choose when raw processing throughput > display subsystem integration, and thermal budget permits higher power draw |
Compared with STM32F767ZIT6, the STM32F765IIK7 adds MIPI DSI host and removes Ethernet PHY, making it optimal for compact, display-centric edge devices; versus STM32H743VIT6, it trades peak clock speed and dual-core capability for lower static power and integrated DSI, better suited for battery-aware portable HMIs.

FAQ
What is the maximum operating frequency and how is it achieved?
The STM32F765IIK7 achieves 216 MHz via its Arm Cortex-M7 core with ART Accelerator and 16 KB L1 cache, enabling zero-wait-state execution from flash. Stable operation requires proper decoupling on VCAP1/VCAP2 pins and adherence to voltage (1.7–3.6 V) and temperature (–40°C to +105°C) specifications per DS11532 Rev 9 Section 6.3.1.
Does this MCU support MIPI DSI displays natively?
Yes - the STM32F765IIK7 integrates a compliant MIPI DSI Host controller (DSIHOST) with embedded D-PHY v1.2, supporting up to 4 data lanes and 720p@30 Hz resolution. It includes hardware lane calibration, LP/HS mode switching, and dedicated DSI PLL with regulator, as confirmed in Section 3.47 and Table 11 of DS11532 Rev 9.
How does dual-bank flash improve firmware update reliability?
Dual-bank flash allows one bank to execute code while the other is erased and reprogrammed - enabling atomic, fail-safe firmware updates without halting real-time operations. This architecture is validated in STM32F765xx reference manuals and used in IEC 62443-compliant industrial firmware update schemes.
What peripheral resources are allocated to graphics acceleration?
Graphics acceleration relies on three dedicated hardware blocks: Chrom-ART Accelerator (DMA2D) for 2D composition, JPEG codec for image compression/decompression, and LCD-TFT + DSI Host controllers for display output. All operate independently of the CPU, with DMA2D achieving up to 1 Gpixel/s throughput per DS11532 Section 3.11.
