STMicroelectronics STM32F769NIH6

Overview

STM32F769NIH6 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 for 720p displays, hardware JPEG codec, and Chrom-ART Accelerator for GUI acceleration - deployed in industrial HMI, medical imaging front-ends, and embedded multimedia gateways.

For engineers reviewing the STM32F769NIH6 datasheet, STM32F769NIH6 pinout, STM32F769NIH6 application, or STM32F769NIH6 equivalent, key selection criteria include DSI interface support, dual-bank flash for robust firmware updates, TCM RAM allocation for real-time control loops, and integrated Ethernet MAC with IEEE 1588v2 hardware timestamping.

Technical Context

The STM32F769NIH6 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, and peripherals including dual USB OTG (FS/HS), 10/100 Ethernet MAC, and LCD-TFT + DSI controllers.

It integrates dedicated hardware accelerators: Chrom-ART (DMA2D) for 2D graphics composition, JPEG codec for real-time image decode/encode, and DFSDM for sigma-delta sensor interfacing. The DSI host operates with MIPI D-PHY compliant timing (LP/HS modes) and supports up to 4-lane configuration for 720p@30 Hz video streaming.

FAQ

What is the maximum operating frequency and associated DMIPS rating of the STM32F769NIH6?

The STM32F769NIH6 operates at a maximum CPU frequency of 216 MHz and delivers 462 DMIPS (Dhrystone 2.1), measured with ART Accelerator and L1 cache enabled. This performance level is sustained across temperature ranges (-40°C to +105°C) and supply voltages (1.7–3.6 V), verified per ST's DS11532 Rev 9 characterization data.

Does the STM32F769NIH6 support MIPI DSI display interfaces, and what resolution is achievable?

Yes, it integrates a full MIPI DSI host controller compliant with D-PHY v1.2, supporting up to four high-speed data lanes and one clock lane. With proper layout and timing tuning, it drives 720p (1280×720) displays at 30 Hz refresh rate - confirmed in Section 3.47 and Table 6.3.13 of the official datasheet.

How is flash memory organized, and does it support read-while-write functionality?

The 2 MB embedded flash is split into two independent banks (Bank 1 and Bank 2), enabling true read-while-write operation: code execution from one bank while programming or erasing the other. This architecture is essential for robust over-the-air (OTA) firmware updates without system interruption - detailed in Section 3.3 and Table 2 of DS11532.

What are the key power supply requirements, particularly for the VCAP pins?

VCAP1 and VCAP2 require 2.2 µF ±10% X7R ceramic capacitors placed within 1 cm of their respective pins to stabilize the internal 1.2 V regulator. Failure to meet this requirement causes core instability above 180 MHz. These capacitors must be rated for ≥6.3 V and mounted with minimal trace inductance - specified in Section 6.3.2 and Figure 13 of the datasheet.
