STMicroelectronics STM32F767NIH6

Overview

STM32F767NIH6 from STMicroelectronics is an Arm® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, featuring 2 MB dual-bank flash, 512 KB + 16 KB + 4 KB RAM, USB OTG HS/FS, LCD-TFT controller, MIPI DSI host, and Ethernet MAC. It serves as a high-performance application processor in industrial HMI, medical imaging front-ends, and networked edge gateways requiring real-time graphics and connectivity.

For engineers reviewing the STM32F767NIH6 datasheet, STM32F767NIH6 pinout, STM32F767NIH6 application, or STM32F767NIH6 equivalent, key selection criteria include its 216 MHz Cortex-M7 core with L1 cache, dual-bank flash for seamless firmware updates, integrated Chrom-ART Accelerator for GUI rendering, and hardware JPEG codec for embedded vision preprocessing.

Technical Context

The STM32F767NIH6 implements a tightly coupled memory architecture with 16 KB I/D cache, ART Accelerator, and dual TCM RAM (128 KB data + 16 KB instruction) to sustain zero-wait-state execution at 216 MHz. Its AXI-AHB bus matrix enables concurrent access to flash, SRAM, and peripherals without contention.

It integrates three independent CAN 2.0B controllers, dual SDMMC interfaces, IEEE 1588v2-compliant 10/100 Ethernet MAC with dedicated DMA, and a MIPI D-PHY compliant DSI host supporting up to 720p@30 Hz - enabling direct connection to display modules without external bridge ICs.

FAQ

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

The STM32F767NIH6 achieves 216 MHz maximum CPU frequency using its internal PLL with external 4–26 MHz crystal oscillator input. This requires proper configuration of the voltage regulator (VOS scale 1), enabling ART Accelerator and L1 cache, and supplying stable 3.3 V with low-ESR decoupling capacitors on VCAP1/VCAP2 pins as specified in Section 6.3.2 of DS11532 Rev 9.

Does STM32F767NIH6 support hardware JPEG encoding or only decoding?

The STM32F767NIH6 integrates a hardware JPEG codec capable of both encoding and decoding operations, as confirmed in Section 3.13 of the datasheet. It supports baseline JPEG (ISO/IEC 10918-1) with programmable quality factor and subsampling (4:2:2, 4:2:0), enabling real-time compression of camera-captured images without CPU intervention.

Can the DSI host interface drive standard MIPI DSI panels without external PHY?

Yes - the STM32F767NIH6's DSI host includes integrated MIPI D-PHY compliant transmitter circuitry (Section 3.47, DS11532 Rev 9). It directly drives MIPI DSI panels requiring LP/HS signaling, eliminating need for external D-PHY ICs; however, proper PCB layout (matched-length differential pairs, controlled impedance) is mandatory for reliable 720p@30 Hz operation.

What debug interfaces are supported and what trace capability exists?

The STM32F767NIH6 supports SWD and JTAG debug interfaces, plus Cortex-M7 Trace Macrocell™ (ETM) for instruction-level tracing. ETM enables non-intrusive real-time code flow analysis via SWO or external trace port, essential for optimizing interrupt latency and verifying hard real-time behavior in safety-critical applications.
