Product details
Overview
STM32F765BGT6 from STMicroelectronics is an 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, MIPI DSI host controller, and LCD-TFT controller supporting XGA resolution. It targets high-performance embedded applications such as industrial HMIs, medical imaging front-ends, and real-time motor control systems.
For engineers reviewing the STM32F765BGT6 datasheet, STM32F765BGT6 pinout, STM32F765BGT6 application, or STM32F765BGT6 equivalent, key selection considerations include dual-bank flash for seamless firmware updates, hardware JPEG codec for image processing acceleration, Chrom-ART DMA2D accelerator for GUI rendering, and integrated Ethernet MAC with IEEE 1588v2 support for time-sensitive networking.
Technical Context
The device implements a tightly coupled memory architecture with 16 KB I/D cache, ART Accelerator, and L1-cache enabling zero-wait-state execution from flash or external memories. Its dual-mode Quad-SPI interface supports memory-mapped and direct command modes for fast external code/data access.
It integrates three independent CAN 2.0B controllers, two SDMMC hosts, SPDIFRX, HDMI-CEC, and a 10/100 Ethernet MAC with dedicated DMA and hardware timestamping - making it suitable for deterministic multi-protocol industrial gateways requiring concurrent real-time communication stacks.

| Flash Memory | 2 MB dual-bank flash - allows background read-while-write for live firmware updates without system interruption. |
| SRAM | 512 KB (128 KB data TCM + 16 KB instruction TCM + 4 KB backup) - TCM RAM guarantees deterministic latency for real-time ISR and control loops. |
| Graphics Acceleration | Chrom-ART Accelerator (DMA2D) + hardware JPEG codec - offloads CPU from bitmap blending and image decompression in HMI applications. |
| Display Interface | MIPI DSI host controller (720p@30 Hz) + LCD-TFT controller (XGA) - supports high-resolution touchscreens with low CPU load. |

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 compute-intensive DSP or dual-core RTOS partitioning; lacks native display acceleration for HMI-focused designs. | Select when raw processing throughput or asymmetric multicore is prioritized over integrated display subsystems. |
| STM32F767ZGT6 | Same core/peripherals but in LQFP144 (20×20 mm); adds 2 more USARTs and 1 extra SPI vs. BGT6's LQFP100 footprint. | Enables larger peripheral count in space-constrained designs where pin count exceeds 100; same feature set otherwise. | Choose when additional serial interfaces are required and PCB layout accommodates larger package. |
Compared with STM32H743VIT6, the STM32F765BGT6 offers superior display integration (DSI + JPEG) at lower clock speed, while versus STM32F767ZGT6 it trades pin count for compact LQFP100 packaging - making it optimal for cost- and size-sensitive HMI and imaging edge nodes.

FAQ
What is the maximum operating frequency and how is it achieved?
The STM32F765BGT6 achieves 216 MHz maximum CPU frequency using its internal voltage regulator and external 4–26 MHz crystal oscillator, with the PLL configured to multiply the input clock. Stable operation requires proper decoupling of VCAP1/VCAP2 pins with 2.2 µF capacitors and adherence to power ramp timing specifications during startup.
Does this MCU support external SDRAM, and what interface is used?
Yes, the STM32F765BGT6 supports external SDRAM up to 256 MB via its Flexible Memory Controller (FMC) with 32-bit data bus. The FMC provides dedicated control signals (RAS/CAS, CLK, CKE, etc.) and supports LPDDR/LPSDR SDRAM, enabling expansion of framebuffer or application heap memory beyond on-chip SRAM limits.
How does the dual-bank flash architecture improve firmware update reliability?
Dual-bank flash allows one bank to remain active for program execution while the other is erased and reprogrammed - enabling atomic, fail-safe firmware updates. This eliminates risk of bricking during OTA updates and supports A/B partitioning schemes required by functional safety standards like IEC 61508.
Can the MIPI DSI interface drive standard mobile display panels?
Yes, the MIPI DSI host controller supports standard D-PHY compliant panels up to 720p@30 Hz, including common 5–7 inch TFT modules with 1-lane or 2-lane configurations. It requires external D-PHY level shifters and proper impedance-controlled routing, and supports video mode (non-burst) and command mode (burst) operation per MIPI DSI v1.2 specification.
