STMicroelectronics STM32F767NIH7

Overview

STM32F767NIH7 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, featuring 2 MB dual-bank flash, 512 KB SRAM (including 128 KB data TCM), USB OTG HS/FS, Ethernet MAC, LCD-TFT controller, and MIPI DSI host for embedded graphics applications in industrial HMI and medical imaging systems.

For engineers reviewing the STM32F767NIH7 datasheet, STM32F767NIH7 pinout, STM32F767NIH7 application, or STM32F767NIH7 equivalent, key selection considerations include its 216 MHz CPU clock, dual-bank flash enabling read-while-write, integrated Chrom-ART Accelerator for GUI rendering, hardware JPEG codec, and support for up to XGA resolution displays via LTDC.

Technical Context

The STM32F767NIH7 implements an Arm Cortex-M7 core with tightly coupled memory (TCM) architecture: 128 KB data TCM RAM for real-time data and 16 KB instruction TCM RAM for latency-critical routines, backed by ART Accelerator and 16 KB I/D cache for zero-wait-state execution from flash. Its AXI-AHB bus matrix enables concurrent high-bandwidth access across CPU, DMA, and peripherals.

It integrates dual-mode Quad-SPI for external memory expansion, flexible memory controller (FMC) supporting SDRAM/NOR/NAND, and dedicated hardware blocks including Chrom-ART (DMA2D), JPEG codec, and DSI Host with MIPI D-PHY compliant timing - all synchronized via multiple PLLs (main PLL, PLLSAI, PLLI2S) with independent clock domains for display, audio, and system operation.

Key Specifications

Pinout & Package

The STM32F767NIH7 is housed in a 216-ball TFBGA package (13 × 13 mm, 0.8 mm pitch), compliant with ECOPACK2 environmental standards. Ball pitch and layout align with JEDEC MO-276AB specification.

FAQ

What is the maximum operating frequency and associated power supply requirement for STM32F767NIH7?

The STM32F767NIH7 operates at up to 216 MHz, requiring a 1.7–3.6 V VDD supply with two mandatory 2.2 µF ceramic capacitors on VCAP1 and VCAP2 pins. Stable 216 MHz operation mandates proper PCB layout for VCAP decoupling and adherence to thermal limits specified in the datasheet's thermal characteristics table (θJA = 25.5 °C/W for TFBGA216).

Does STM32F767NIH7 support hardware JPEG encoding and decoding?

Yes, the STM32F767NIH7 integrates a dedicated hardware JPEG codec supporting baseline JPEG encode and decode up to 4096×4096 pixels. It operates independently of the CPU, reducing processing load during image capture or display, and is accessible via DMA for zero-copy transfers between memory and peripheral buffers.

How many I/O pins are 5 V-tolerant, and what is their maximum toggle frequency?

The STM32F767NIH7 provides up to 166 5 V-tolerant I/O pins, all capable of toggling at up to 108 MHz in push-pull mode. These pins maintain compatibility with legacy 5 V logic while operating from a 3.3 V supply, simplifying integration with external sensors, displays, and industrial buses without level shifters.

What debug interfaces does STM32F767NIH7 support, and is SWO trace available?

The STM32F767NIH7 supports both SWD and JTAG debug interfaces, plus Cortex-M7 Trace Macrocell™ (ETM) for instruction and data trace. SWO (Serial Wire Output) is available via PA10 (SWO) pin for real-time printf-style debugging and event tracing when used with compatible debug probes like ST-LINK/V2-1 or J-Link.
