STM32F767IIT6 Présentation
An ARM Cortex-M7 microcontroller (MCU) is a 32-bit processor core designed for high-performance, deterministic embedded applications such as motor control, audio processing, and industrial networking. The Cortex-M7 sits at the top of the Cortex-M family, above Cortex-M4/M33, in the broader taxonomy of microcontrollers -> embedded processors -> semiconductors. It adds dual-issue pipeline, tightly-coupled memory, and SIMD DSP instructions while retaining the deterministic interrupt response that made Cortex-M ubiquitous in real-time designs.
Key features of the STM32F767IIT6 include integrated crypto/hash peripherals (AES, SHA, MD5, HMAC), a TFT LCD controller, a JPEG codec, two USB OTG controllers (FS + HS with PHY), two CAN 2.0B interfaces, an Ethernet MAC, an SDMMC interface, three I2C, six SPI (two with I2S), four USART plus two UART, and 12-bit ADC/DAC blocks. Chrom-ART (DMA2D) acceleration and the proprietary Chrom-GRC graphics functions simplify TFT GUI development.
Architecturally, the part pairs the Cortex-M7 core with a multi-AHB bus matrix, dual-bank Flash for safe field updates, and a flexible low-power run/sleep/stop/standby/shutdown power profile. Internal regulators plus VBAT domain preserve RTC and backup registers during main-rail loss, and four PWM-capable 16-bit timers plus two 32-bit timers support complex motor-control or digital-power topologies.
Typical applications include HMI panels with TFT LCD, industrial PLCs and inverters, audio processing and codec bridging, secure IoT gateways, and USB-based peripherals or test instruments. The wide peripheral mix makes it a single-chip solution for products that previously required an MPU plus external peripherals.
When designing with this MCU, allocate PCB area for LQFP-176 fanout and provide bulk decoupling on each VDDS/VDD pair. Use ST's STM32CubeMX to generate pin mux and clock-tree configurations and validate trace routing for the parallel TFT interface if used.

Applications typiques
STM32F767IIT6 convient pour 6 applications: Industrial HMI with TFT LCD Panel, USB-Based Test and Measurement Instrument, Secure Industrial IoT Gateway, Motor Control and Industrial Drive, Audio Processing and USB Audio Class Device, Data Logger with Ethernet and SD Card.
Industrial HMI with TFT LCD Panel
The STM32F767IIT6 is purpose-built for industrial HMI applications, combining the integrated TFT LCD controller (up to 24-bit parallel RGB) with the Chrom-ART DMA2D accelerator and hardware JPEG codec. Its 2 MB Flash stores UI assets and fonts while 512 KB SRAM accommodates double-buffered framebuffers for flicker-free animation at WXGA resolutions. The 176-pin LQFP exposes the full parallel display interface plus SDRAM bus, allowing direct connection to a TFT panel without an external graphics controller. Industrial temperature range (-40 to +85 C) and EMC-robust GPIO support deployment on factory floors.
Recommandé
USB-Based Test and Measurement Instrument
The dual USB OTG controllers (FS + HS with on-chip PHY) make the STM32F767IIT6 ideal for USB instruments that stream high-bandwidth data to a host PC. The 216 MHz Cortex-M7 with FPU performs real-time DSP on analog inputs while the HS USB pipe delivers samples without CPU intervention via DMA. Combined with three 12-bit ADCs at up to 2.4 MSPS and 512 KB SRAM for sample buffering, the MCU replaces discrete DSP+USB-controller solutions. USB-C power delivery can be implemented on the FS port for self-powered bench instruments.
Recommandé
Secure Industrial IoT Gateway
The hardware AES-128/192/256, SHA-1/2, MD5 and HMAC engines on the STM32F767IIT6 enable TLS/DTLS termination without CPU load - critical for IoT gateways handling MQTT or CoAP traffic at scale. The integrated 10/100 Ethernet MAC with MII/RMII and dual CAN 2.0B interfaces support bridged connectivity between factory-floor PLCs and cloud backends. 2 MB Flash accommodates a full TLS stack plus application code while 512 KB SRAM runs lwIP or mbedTLS concurrently. TrustZone-M is not present on F7, but secure-boot via the integrated RNG and read-protected Flash provides adequate protection for edge deployments.
Recommandé
Motor Control and Industrial Drive
The 12 general-purpose 16-bit timers plus two 32-bit timers on the STM32F767IIT6 deliver the PWM channels needed for three-phase motor control of BLDC, PMSM, or stepper motors. Advanced timers with complementary outputs and programmable dead-time insertion simplify inverter half-bridge drive. The 216 MHz core executes field-oriented control loops within microseconds while the fast 12-bit ADC (2.4 MSPS) samples phase currents synchronously. CAN 2.0B integration allows direct connection to industrial fieldbus networks without an external transceiver MCU.
Recommandé
Audio Processing and USB Audio Class Device
The STM32F767IIT6 is popular for USB audio interfaces, MIDI controllers, and digital mixers because of its I2S-capable SPI ports, SAI interface, and 12-bit DAC for monitoring outputs. The hardware AES block can encrypt audio streams for secure conferencing applications. 512 KB SRAM buffers audio frames while the HS USB delivers multichannel uncompressed audio at low latency. The integrated TFT controller doubles the MCU as a touchscreen control surface for digital mixers, eliminating the need for a separate display MCU.
Recommandé
Data Logger with Ethernet and SD Card
The two SDMMC interfaces on the STM32F767IIT6 support simultaneous SD card storage plus Wi-Fi module SDIO connectivity, ideal for remote data loggers. The integrated Ethernet MAC and 2 MB Flash provide ample code space for FATFS plus HTTP/Modbus servers, while 512 KB SRAM accommodates TCP/IP socket buffers for high-throughput logging. RTC with VBAT domain plus low-power standby modes allows battery-backed timestamped logging across power cycles. The hardware CRC and AES accelerators ensure logged data integrity and optional encryption at rest.

Notes de conception
Provide at least 4.7 uF bulk decoupling on each VDD/VDDA/VDDUSB pin plus 100 nF ceramic caps within 2 mm of every supply pin. The 216 MHz core draws up to ~300 mA peak and inrush during Flash programming requires 4.7 uF minimum to prevent voltage droop. Place a ferrite bead between VDD and VDDA to isolate the analog domain from switching noise of the USB PHY and Ethernet MAC.
The 176-pin LQFP (24x24 mm) has 0.5 mm pitch - fanout requires either a 4-layer PCB with buried vias or a 2-layer PCB with via-in-pad if area is constrained. Route the parallel RGB bus with matched-length tracks (tolerance +/-100 mil) and keep SDRAM traces away from switching supplies. Use a continuous ground pour under the package thermal pad area to improve thermal dissipation and provide return-path continuity.
Do not enable the L1-cache in startup code without flushing - cache coherency issues with DMA buffers are the most common bug on STM32F7 designs. Use the cache maintenance macros (SCB_CleanDCache_by_Addr / SCB_InvalidateDCache_by_Addr) around DMA buffers that the CPU also reads. Estimated: at 216 MHz, with cache disabled the core runs at ~75% of the rated performance so benchmark your critical loops.
Keep the HSE crystal traces within 2 mm of the OSC_IN/OSC_OUT pins with a ground guard ring to minimize EMI. Place the 32.768 kHz LSE crystal close to the RTC domain and route VBAT through a ferrite if VBAT is shared with a backup battery. The USB HS PHY requires 90 ohm differential impedance on D+/D- traces - calibrate trace width to your stackup before PCB fabrication.
