STM32F750N8H6 Overview
An Arm Cortex-M7 MCU is a 32-bit microcontroller core designed for high-performance embedded applications, featuring a superscalar pipeline, single-precision floating-point and DSP instructions, and an integrated MPU. The STM32F750 family targets human-machine interface, motor control, and audio applications where deterministic real-time performance, rich connectivity, and large SRAM buffers are required within a low-power envelope.
Key features include 216 MHz fCPU with 462 DMIPS, 64 KB Flash with ART Accelerator (zero wait-state execution from Flash), 340 KB total SRAM (320 + 16 + 4 KB), Chrom-ART graphics accelerator for 2D DMA2D, 12-bit ADC up to 2.4 MSPS, two 12-bit DACs, USB OTG Full-Speed and High-Speed with dedicated PHY, two CAN 2.0B interfaces, SDMMC host, and a TFT-LCD controller with dedicated pixel clock. Operating voltage ranges from 1.8 V to 3.6 V.
The Cortex-M7 core integrates a double-precision FPU and tightly-coupled memory to deliver deterministic interrupt latency under 20 ns, enabling precise motor-control loops and high-fidelity digital signal processing. The integrated Chrom-ART Accelerator offloads 2D operations from the CPU, freeing cycles for application code while sustaining pixel throughput to a TFT display without CPU intervention.
Typical applications include TFT-LCD HMI panels, industrial motor drives, audio processing (MP3/WMA codecs, audio DAC control), point-of-sale terminals, and PLC controllers. The USB OTG HS and CAN 2.0B ports enable connectivity-rich gateways, while the dedicated camera interface and SRAM headroom are well suited to basic image processing.
A primary design consideration is power rail sequencing: the MCU integrates a Power-on Reset and brown-out detector that requires VDD to reach the minimum operating threshold before any I/O is driven. Designers should also budget for the external 25 MHz HSE crystal plus 32.768 kHz LSE, since internal HSI alone is too inaccurate for USB and CAN operation in production designs.

Typical Applications
STM32F750N8H6 is suitable for 6 applications: Industrial TFT HMI Panel, Industrial Motor Drive (FOC), Audio Processing / Codec Subsystem, USB Host Gateway / POS Terminal, Camera-Based Vision Module (Entry-Level), Industrial IoT Gateway / Sensor Hub.
Industrial TFT HMI Panel
The STM32F750N8H6 drives TFT-LCD human-machine interface panels up to XGA resolution via its integrated LTDC controller and dedicated pixel clock. With the Chrom-ART Accelerator (DMA2D) the core offloads 2D blit/fill operations so the Cortex-M7 can run UI logic concurrently. At 216 MHz and 462 DMIPS the MCU sustains 60 fps animated menus and runs LVGL/STM32 emWin stacks, while the 12-bit ADC at 2.4 MSPS provides touch-screen and analog sensor sampling. Place between a 3.3 V regulator rail and the LCD with 100 nF + 4.7 uF decoupling near each VDD pin, and route the parallel display bus with 22 ohm series damping to limit EMI on cables.
Recommended
Industrial Motor Drive (FOC)
Field-Oriented Control of 3-phase PMSM or BLDC motors is achieved by the STM32F750N8H6 using its 216 MHz Cortex-M7 core, hardware FPU, and 340 KB of SRAM for fast trigonometric tables and observer state. The advanced timers (TIM1, TIM8) deliver complementary PWM with dead-time insertion up to 144 MHz while the dual 12-bit ADCs sample phase currents simultaneously at 2.4 MSPS in interleaved mode. The MCU runs deterministic torque loops under 20 us and supports sensorless operation via BEMF comparators and the integrated op-amps (when available in the line). Add 100 nF + 10 uF decoupling on each VDD pin and route the high-current motor traces away from analog inputs.
Recommended
Audio Processing / Codec Subsystem
Audio playback, MP3/WMA decoding and real-time effects run reliably on the STM32F750N8H6 thanks to its Cortex-M7 DSP extensions, MAC, and 340 KB SRAM for circular audio buffers. The two 12-bit DACs and SAI/I2S ports drive external audio DACs; the SPDIF-Rx and DFSDM support digital-microphone arrays for beam-forming. At 216 MHz the MCU can decode 192 kHz/24-bit streams with headroom for software equalization. Couple with a low-noise LDO such as TPS7A4701 for the analog supply and route the I2S/SAI data lines length-matched with controlled impedance 50 ohm.
Recommended
USB Host Gateway / POS Terminal
The STM32F750N8H6 acts as a USB OTG High-Speed host gateway in point-of-sale and KIOSK terminals, thanks to its dedicated HS PHY without an external ULPI chip and dual CAN 2.0B ports for back-office links. At 216 MHz the Cortex-M7 core can run USB stack plus TCP/IP mDNS concurrently while sustaining 480 Mbps to peripherals. The 64 KB Flash is sufficient for embedded USB-class stacks, though the STM32F746ZGT7 is recommended for richer web-server workloads. Provide a 24 MHz crystal for the HS PHY reference clock (not 25 MHz), place the PHY-specific ferrite bead on the VDD-USB rail.
Recommended
Camera-Based Vision Module (Entry-Level)
Basic embedded-vision tasks such as barcode/QR scanning and presence detection are handled by the STM32F750N8H6 through its 8- to 14-bit parallel camera interface (DCMI) and enough SRAM for line buffers in 640x480 frames. The Chrom-ART Accelerator accelerates format conversion (RGB-to-YUV) while the Cortex-M7 runs a lightweight YOLO/vision classifier at modest frame rates. With 64 KB Flash the MCU fits small CNN models, while a larger sibling like STM32F746IGT6 is needed for 1 MB model files. Use 4-layer PCB with matched-impedance camera bus and add ESD diodes on the data lines.
Recommended
Industrial IoT Gateway / Sensor Hub
An industrial IoT gateway built on the STM32F750N8H6 aggregates multiple sensor interfaces (CAN, UART, SPI, I2C, SDMMC) and uploads via Wi-Fi/Ethernet through a companion module. The 340 KB SRAM buffers burst-mode sensor data; the FPU processes sensor-fusion calculations in floating-point. The dual CAN 2.0B ports, USB OTG HS, and SDMMC host enable gateway-class connectivity at the network edge. Provide a 32.768 kHz LSE crystal for RTC calendar accuracy and route the RTC backup domain to a separate coin-cell rail.

Key Differentiators
- Highest Cortex-M7 throughput in the F750 family with dedicated hardware FPU + DSP (vs STM32F746ZGT7)
- Largest package in the STM32F750 line for maximum GPIO count (vs STM32F750Z8H6)
- Minimal Flash footprint keeps BOM cost low for headless gateways (vs STM32F756NGH6)
Design Notes
The STM32F750N8H6 requires a stable 3.3 V supply on VDD/VDDA and a separate coin-cell on VBAT for the RTC and 4 KB backup SRAM. Place 100 nF X7R ceramics as close as possible to every VDD pin and a bulk 4.7 uF tantalum or ceramic on VDDA to keep ADC noise within 1 LSB at 2.4 MSPS.
Estimated: at 216 MHz with all peripherals active, the STM32F750N8H6 dissipates around 250-300 mW in typical usage. The TFBGA-216 package has limited heat dissipation; for sustained CPU loads above 70% utilization add a 4-layer PCB with 1 oz copper and a thermal via array beneath the GND balls to keep junction temperature below 85C.
Route the SDIO/SDMMC bus to match length within 1 mm and keep it away from noisy inductors; place a 10 ohm resistor in series with SDIO_CLK to suppress harmonics. The USB HS PHY should route DP/DN pair with 90 ohm differential impedance and a 24 MHz reference crystal within 5 mm of the OSC pins.
Critical: do not power up without a stable HSE/HSI clock source for the USB HS PHY; floating REF_CLK can latch spurious transitions. Also avoid driving the BOOT0 pin to VDD unless intentionally entering System Memory bootloader, since the MCU will reset into bootloader mode on every reset event.
