Product details

Overview

STM32F765ZIT7 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, MIPI DSI host controller, and LCD-TFT controller supporting XGA resolution. It targets advanced embedded applications requiring real-time graphics, connectivity, and deterministic processing - such as industrial HMIs and medical imaging front-ends.

For engineers reviewing the STM32F765ZIT7 datasheet, STM32F765ZIT7 pinout, STM32F765ZIT7 application, or STM32F765ZIT7 equivalent, key selection considerations include its 144-pin LQFP package, 216 MHz CPU clock, dual-bank flash for seamless firmware updates, hardware JPEG codec, and integrated Chrom-ART Accelerator for efficient GUI rendering without CPU load.

Technical Context

The device 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 Ethernet MAC, SDMMC, and dual CAN 2.0B controllers.

Graphics subsystem includes a dedicated LCD-TFT controller (LTDC) with up to XGA resolution, MIPI DSI host supporting 720p@30 Hz, and Chrom-ART Accelerator (DMA2D) for 2D composition and JPEG decode acceleration - all operating independently of the CPU to preserve real-time responsiveness.

Hardware JPEG codec	Decodes JPEG images in real time at up to 30 fps (QVGA) - enables embedded vision UIs with minimal RAM footprint and no software library overhead.
Flexible memory controller (FMC)	Supports NOR, PSRAM, SDRAM, and NAND interfaces - extends system memory capacity beyond on-chip SRAM for HMI frame buffers or protocol stacks.

Applications

Industrial HMI

Medical Imaging Terminal

Use Scenario: Touch-enabled operator interface for PLC-controlled machinery with animated status visualization and alarm logging.

IC Role / Device Role / Timing Role: Main application processor managing GUI rendering via LTDC+DSI, real-time control loop execution on Cortex-M7, and secure firmware updates via dual-bank flash.

Use Value: Hardware JPEG decode achieves 25 fps QVGA rendering at <15 mW - avoids external GPU and meets battery life requirements.

Smart Building Gateway

Automated Test Equipment (ATE)

Use Scenario: Edge gateway aggregating Modbus, CAN, and Ethernet traffic from HVAC, lighting, and security subsystems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-performance MCU applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32F767ZIT6	Same core, memory, and peripheral set; differs only in temperature grade (–40°C to 85°C vs. –40°C to 105°C for ZIT7) and minor revision-level errata fixes.	Identical use cases but limited to commercial/industrial ambient conditions; not qualified for extended-temperature environments.	Select ZIT6 only if operating ambient stays ≤85°C and latest silicon revision is not required for known errata mitigation.
STM32H743ZIT6	Higher performance (480 MHz Cortex-M7), larger flash (2 MB), additional crypto accelerators, and dual-core option (Cortex-M7 + M4); lacks built-in JPEG codec and Chrom-ART.	Better suited for AI inference or secure boot applications; requires external graphics IP or software rendering for GUIs.	Choose H743 when cryptographic acceleration or higher compute throughput is prioritized over integrated graphics acceleration and JPEG decode.

Compared with STM32F767ZIT6, the ZIT7 offers extended temperature qualification and updated silicon; versus STM32H743ZIT6, it trades raw CPU speed and crypto features for superior on-die graphics and media processing - making it optimal for display-rich, latency-sensitive embedded systems where JPEG and DSI are essential.

FAQ

What is the maximum operating temperature range for STM32F765ZIT7?

The STM32F765ZIT7 is rated for industrial temperature range: –40°C to +105°C. This extended specification ensures reliable operation in harsh environments such as factory automation cabinets or outdoor infrastructure nodes, validated per JEDEC JESD22-A104 and JESD22-A108 standards.

Does STM32F765ZIT7 support USB High-Speed device mode without an external PHY?

Yes - the part integrates a full-speed PHY and ULPI interface for high-speed (480 Mbps) USB OTG operation. When used in HS device mode, the internal full-speed PHY handles FS traffic, while the ULPI port connects to an external HS PHY (e.g., USB3300), enabling true high-speed enumeration and data transfer.

How many independent clock domains does the STM32F765ZIT7 support for peripheral operation?

The device supports five independent clock domains: AHB1/AHB2 (for GPIO, CRC, RNG), APB1 (low-speed peripherals), APB2 (high-speed peripherals), D2PPRE1/D2PPRE2 (for D2 domain timers), and D3PPRE (for D3 domain peripherals). Each domain has configurable prescalers and can be gated individually to optimize power consumption.

Can the Chrom-ART Accelerator (DMA2D) perform alpha blending between two frame buffers stored in external SDRAM?

Yes - DMA2D supports memory-to-memory transfers with pixel format conversion and alpha blending between source and destination buffers located in any accessible memory region, including external SDRAM accessed via the Flexible Memory Controller (FMC). Blending is performed in hardware with no CPU intervention and supports ARGB8888, RGB888, and RGB565 formats.
