STMicroelectronics STM32F765NIH6

Overview

STM32F765NIH6 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 memory, 512 KB + 16 KB + 4 KB RAM, and native USB OTG HS/FS, Ethernet MAC, LCD-TFT, and MIPI DSI support - deployed in industrial HMI, medical imaging front-ends, and real-time motor control systems.

For engineers reviewing the STM32F765NIH6 datasheet, STM32F765NIH6 pinout, STM32F765NIH6 application, or STM32F765NIH6 equivalent, key selection criteria include its 216 MHz Cortex-M7 core with L1 cache, dual-bank flash for seamless firmware updates, hardware JPEG codec, Chrom-ART Accelerator (DMA2D), and TFBGA176 package with 166 5 V-tolerant I/Os.

Technical Context

The device 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. It integrates dual-mode Quad-SPI, flexible memory controller (FMC) supporting SDRAM/NOR/NAND, and dual SAIs with audio PLLs for multi-channel audio processing.

Its advanced connectivity stack includes three CAN 2.0B controllers, dual SDMMC interfaces, SPDIFRX, HDMI-CEC, MDIO slave, and IEEE 1588v2-compliant 10/100 Ethernet MAC with dedicated DMA - all synchronized via a multi-layer AXI-AHB bus matrix and configurable clock tree with multiple PLLs (main, audio, SAI).

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32F765NIH6 achieves 216 MHz via its Arm Cortex-M7 core with ART Accelerator and 16 KB I/D cache, which eliminates wait states during flash execution. This frequency requires proper VCAP1/VCAP2 capacitor placement (2.2 µF each), stable 1.7–3.6 V supply, and correct PLL configuration (e.g., HSE + PLL with DIVR=2). Thermal derating applies above 85°C ambient.

Does STM32F765NIH6 support hardware JPEG encoding and decoding?

Yes - it integrates a dedicated hardware JPEG codec capable of real-time encoding and decoding of baseline JPEG images up to 1024×768 resolution. The codec operates independently of the CPU, uses DMA for pixel data transfer, and supports YUV422/RGB565 input formats. No external memory or software library is required for basic compression/decompression.

How many I/O pins are 5 V-tolerant and what is their voltage rating?

STM32F765NIH6 provides 166 5 V-tolerant I/Os across GPIO ports A–K. These pins accept input voltages up to 5.5 V regardless of VDD level (1.7–3.6 V), enabling direct interfacing with legacy 5 V logic, sensors, or displays without level shifters - confirmed per DS11532 Rev 9, Section 6.3.20.

What debug interfaces are supported and what trace capability exists?

The device supports SWD and JTAG via dedicated pins (SWCLK, SWDIO, JTCK, JTMS, etc.) and includes a Cortex-M7 Trace Macrocell™ (ETM) for instruction-level tracing. Full trace requires external debugger (e.g., ST-LINK/V3 or J-Trace) and sufficient bandwidth; trace port pins (TRACECLK, TRACED0–3) are multiplexed with GPIOs and must be enabled in system configuration.
