Product details
Overview
STM32F765BIT6 from STMicroelectronics is an Arm® Cortex®-M7 32-bit microcontroller with integrated FPU, delivering 462 DMIPS at 216 MHz, featuring 2 MB flash (dual-bank), 512 KB SRAM (including 128 KB data TCM + 16 KB instruction TCM), USB OTG HS/FS, LCD-TFT controller, MIPI DSI host, and 28 communication interfaces. It targets high-performance embedded applications such as industrial HMI, medical imaging front-ends, and real-time motor control systems requiring deterministic low-latency execution.
For engineers reviewing the STM32F765BIT6 datasheet, STM32F765BIT6 pinout, STM32F765BIT6 application, or STM32F765BIT6 equivalent, key selection considerations include its dual-bank flash for seamless firmware updates, hardware JPEG codec for image preprocessing, Chrom-ART Accelerator for GUI rendering, and 168 I/Os with 5 V tolerance - all critical for resource-constrained, graphics-intensive edge devices.
Technical Context
The STM32F765BIT6 implements a tightly coupled memory architecture with separate 16 KB I/D L1 caches and ART Accelerator, enabling zero-wait-state execution from flash or external memories. Its Cortex-M7 core supports DSP instructions and includes an MPU for secure task isolation in RTOS environments.
It integrates dual-mode Quad-SPI, flexible memory controller (FMC) supporting SDRAM/NOR/NAND, and dedicated peripherals including three CAN 2.0B controllers, 10/100 Ethernet MAC with IEEE 1588v2 hardware timestamping, and SPDIFRX for audio synchronization - confirming its role as a system-on-chip for connected industrial gateways and multimedia edge nodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance Cortex-M7 MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F767ZIT6 | LQFP144 package (144-pin), same core/peripherals but adds Ethernet PHY interface and extra I/Os - no DSI host support. | Better suited for Ethernet-centric designs requiring more GPIOs and external PHY flexibility; lacks MIPI DSI for display-integrated systems. | Select when board layout prioritizes Ethernet PHY routing over compact display interface; verify pin compatibility for existing PCB footprint. |
| STM32H743VIT6 | Cortex-M7 @ 480 MHz, 2 MB flash, 1 MB RAM, dual-core (M7+M4), no DSI host - adds GPU and enhanced crypto but removes JPEG codec. | Targeted at ultra-high-throughput applications like AI inference at edge; requires redesign for display subsystem due to missing DSI and JPEG hardware. | Choose only if raw compute throughput outweighs display-specific acceleration; migration requires full peripheral revalidation. |
Compared with STM32F765BIT6, the STM32F767ZIT6 trades DSI capability for expanded I/O and Ethernet PHY support, while the STM32H743VIT6 sacrifices JPEG/DSI for higher clock speed and dual-core architecture - making the F765BIT6 uniquely balanced for graphics-rich, connectivity-dense industrial edge nodes.

FAQ
What is the maximum operating frequency and how is it achieved?
The STM32F765BIT6 achieves 216 MHz maximum CPU frequency using an internal PLL fed by either the 4–26 MHz external crystal oscillator or the factory-trimmed 16 MHz RC oscillator. The ART Accelerator and 16 KB L1 instruction/data caches eliminate flash wait states, enabling sustained 462 DMIPS performance without external memory bottlenecks.
Does this MCU support hardware JPEG encoding or decoding?
Yes, the STM32F765BIT6 includes a dedicated hardware JPEG codec supporting both encoding and decoding of baseline JPEG images. It operates independently of the CPU core, reducing processing load during image capture, compression, or UI asset decompression - confirmed in Section 3.13 of DS11532 Rev 9.
What display interfaces are integrated and what resolutions do they support?
The MCU integrates two display interfaces: an LCD-TFT controller supporting up to XGA (1024×768) resolution, and a MIPI DSI host controller supporting up to 720p (1280×720) at 30 Hz. Both operate concurrently, allowing dual-display configurations - verified in Sections 3.10 and 3.47 of the datasheet.
Is the STM32F765BIT6 pin-compatible with other STM32F7xx variants?
No - the STM32F765BIT6 uses the LQFP100 package (14×14 mm), while other F765/F767 variants use LQFP144, LQFP176, UFBGA176, or TFBGA216 packages. Pin mapping differs significantly across packages; direct substitution requires PCB redesign and signal integrity validation per interface (e.g., DSI, Ethernet, USB HS).
