Product details
Overview
STM32F769BGT6 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), MIPI DSI host controller supporting 720p@30 Hz, and integrated Chrom-ART Accelerator for embedded GUIs - used in industrial HMI panels with high-resolution touch displays.
For engineers reviewing the STM32F769BGT6 datasheet, STM32F769BGT6 pinout, STM32F769BGT6 application, or STM32F769BGT6 equivalent, key selection criteria include DSI interface capability, dual-bank flash for robust firmware updates, TCM RAM allocation for real-time control loops, and 166 5 V-tolerant I/Os for mixed-voltage system interfacing.
Technical Context
The STM32F769BGT6 implements a tightly coupled Arm Cortex-M7 core with ART Accelerator and 16 KB I/D cache, enabling zero-wait-state execution from flash or external memory. Its memory subsystem includes dedicated instruction and data TCM RAM, plus 4 KB backup SRAM powered by VBAT.
It integrates dual-mode Quad-SPI, hardware JPEG codec, LCD-TFT controller (XGA), and MIPI DSI host with D-PHY compliant timing - all coordinated via AXI/AHB bus matrix and DMA2D for graphics offload. The device supports IEEE 1588v2 Ethernet MAC and three CAN 2.0B controllers for deterministic industrial networking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M7 with FPU, 216 MHz max frequency, 462 DMIPS - enables real-time signal processing and complex UI rendering in single-chip HMI designs. |
| Flash Memory | 2 MB dual-bank flash - supports read-while-write for seamless firmware updates without interrupting operation. |
| SRAM | 512 KB total: 128 KB data TCM + 16 KB instruction TCM + 4 KB backup - TCM blocks guarantee deterministic latency for time-critical tasks. |
| DSI Interface | MIPI DSI host controller, up to 720p@30 Hz - drives high-resolution display modules directly without external bridge ICs. |

Pinout & Package
LQFP100 (14 × 14 mm, 0.5 mm pitch) package with exposed thermal pad; RoHS-compliant ECOPACK2 finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VDDIO2 | Core, analog, and I/O supply rails | Separate 1.7–3.6 V domains enable noise isolation between ADC, CPU, and digital I/O sections. |
| VCAP1 / VCAP2 | Internal voltage regulator decoupling | Requires 2.2 µF ceramic capacitors per pin - critical for stable 1.2 V core regulation at 216 MHz. |
| PH13–PH15, PI0–PI11 | DSI host data/lane/control signals | Dedicated high-speed differential pairs (CLKP/N, D0P/N–D3P/N) meeting MIPI D-PHY v1.2 timing specs. |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/O with multiple AFs | Each pin supports up to 16 alternate functions including FMC, DSI, SDMMC, and Ethernet MII - enables flexible board routing. |
| NRST | Active-low reset input | Accepts 1.65–3.6 V logic; internal pull-up ensures reliable power-on reset without external circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| ART Accelerator + L1 cache | Enables zero-wait-state execution from flash, eliminating performance penalty of embedded non-volatile storage. |
| Dual-bank flash architecture | Allows background firmware update: one bank executes while the other receives new image - no system downtime. |
| Chrom-ART Accelerator (DMA2D) | Performs 2D graphics operations (copy, fill, blend) autonomously - frees Cortex-M7 for application logic, not pixel math. |
| Hardware JPEG decoder | Decompresses JPEG images in ~10 ms for 640×480 frames - accelerates dynamic UI asset loading without CPU overhead. |
| MIPI DSI host with D-PHY | Direct interface to display modules using industry-standard DSI protocol - eliminates need for external display bridge ICs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F767ZGT6 | LQFP144 package (20 × 20 mm), adds FMC interface and extra Ethernet PHY pins; no DSI host. | Better suited for external SDRAM-based GUIs or FPGA co-processing; lacks native display interface. | Select when external memory expansion or FPGA connectivity outweighs integrated DSI requirements. |
| STM32H743BIT6 | Higher clock (480 MHz), dual-core (Cortex-M7 + M4), 1 MB flash, no DSI host but adds LTDC + RGB interface. | Targets ultra-high-performance UIs with external RGB display drivers; requires additional display bridge IC. | Choose for >1000 DMIPS compute needs and multi-core RTOS partitioning - not for direct DSI panel integration. |
Compared with STM32F767ZGT6 and STM32H743BIT6, the STM32F769BGT6 uniquely balances DSI-native display driving, dual-bank flash reliability, and industrial connectivity - making it optimal for compact, self-contained HMI designs where display interface integration reduces layer count and EMI risk.

FAQ
What is the maximum operating frequency and associated power supply requirement?
The STM32F769BGT6 operates at up to 216 MHz with a core supply (VDD) of 1.7–3.6 V. Stable operation at full speed requires 2.2 µF ceramic capacitors on both VCAP1 and VCAP2 pins, and VDD must be regulated within ±2% tolerance under dynamic load conditions per Section 6.3.2 of DS11532 Rev 9.
Does this MCU support hardware-accelerated graphics rendering?
Yes - it integrates the Chrom-ART Accelerator (DMA2D), which performs 2D graphics operations including memory-to-memory copy, pixel format conversion, and alpha-blending without CPU intervention. It also includes a hardware JPEG decoder capable of decoding 640×480 images in under 10 ms.
What display interfaces does the STM32F769BGT6 natively support?
The device features a MIPI DSI host controller compliant with D-PHY v1.2, supporting up to four data lanes and clock lane for resolutions up to 720p@30 Hz. It does not include an RGB or LVDS interface; external display bridges are required for those standards.
How many CAN interfaces are available and what protocol versions do they support?
The STM32F769BGT6 integrates three bxCAN controllers, each compliant with ISO 11898-1:2015 (CAN 2.0B Active). All support both standard (11-bit) and extended (29-bit) identifier formats, programmable bit timing, and automatic retransmission - validated per ST's AN4917 application note.
