STMicroelectronics STM32F769AIY6UTR

Overview

STM32F769AIY6UTR from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with integrated FPU, delivering 462 DMIPS at 216 MHz, 2 MB dual-bank flash, 512 KB SRAM (including 128 KB data TCM), and native MIPI DSI host controller supporting 720p@30 Hz for embedded display systems. It integrates Chrom-ART Accelerator, hardware JPEG codec, LCD-TFT controller, USB OTG HS/FS, 10/100 Ethernet MAC, and three CAN 2.0B interfaces - deployed in industrial HMIs, medical imaging front-ends, and connected multimedia gateways.

For engineers reviewing the STM32F769AIY6UTR datasheet, STM32F769AIY6UTR pinout, STM32F769AIY6UTR application, or STM32F769AIY6UTR equivalent, key selection criteria include DSI interface capability, dual-bank flash for robust firmware updates, TCM RAM allocation for real-time control loops, and Ethernet + CAN coexistence in deterministic networking stacks.

Technical Context

The STM32F769AIY6UTR 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 AXI-AHB bus matrix supports concurrent high-bandwidth access to flash, SRAM, FMC, and peripherals including DSIHOST, LTDC, and Ethernet MAC.

It features a dedicated MIPI D-PHY physical layer with programmable PLL and regulator, compliant with MIPI DSI v1.2, and integrates a full-featured LCD-TFT controller (LTDC) with alpha blending and layer composition - both essential for driving high-resolution RGB or DSI panels without external graphics co-processors.

FAQ

What is the maximum DSI video resolution supported by STM32F769AIY6UTR?

The STM32F769AIY6UTR's MIPI DSI host controller supports up to 720p (1280×720) at 30 Hz, verified per MIPI DSI v1.2 specification and confirmed in Section 3.47 and Table 6.3.13 of DS11532 Rev 9. This assumes proper D-PHY timing calibration, correct VDDS_1V2 supply stability, and matching DSI receiver capabilities on the panel side.

Does STM32F769AIY6UTR support USB High-Speed device mode without an external ULPI PHY?

Yes - the STM32F769AIY6UTR integrates a full-speed PHY for USB OTG FS and a dedicated high-speed PHY for USB OTG HS, as stated in Section 2 and Table 2 of DS11532 Rev 9. No external ULPI PHY is required for HS device mode; however, ULPI interface is provided for optional external HS PHY attachment in host configurations.

How is the 512 KB SRAM physically organized, and what is the access latency for TCM regions?

The 512 KB SRAM comprises 128 KB data TCM RAM (DTCM), 16 KB instruction TCM RAM (ITCM), and 384 KB system SRAM - all accessible at full 216 MHz with zero wait states when using TCM regions. DTCM and ITCM are tightly coupled to the Cortex-M7 core, providing deterministic <1-cycle access for time-critical code and data, as detailed in Section 3.5 and Table 6.3.16.

Can STM32F769AIY6UTR execute code directly from external SDRAM via the Flexible Memory Controller?

No - the FMC supports external SDRAM, NOR, PSRAM, and NAND, but code execution is limited to internal flash, ITCM, or system SRAM. External SDRAM is accessible only as data memory; attempting XIP from SDRAM will cause bus fault, as confirmed in Section 3.8 and Table 6.3.30 of DS11532 Rev 9.
