Applications
STM32F746NGH6E suits industrial HMI panels and smart displays requiring a 216 MHz processor with integrated LTDC and MIPI-DSI output on a single chip. It is well-suited for motor-drive systems demanding hard real-time control loops running at sub-microsecond interrupt latencies alongside Ethernet connectivity. Embedded gateway and IoT edge-node designs also leverage its dual USB OTG ports, TrustZone-ready security features, and rich peripheral set in the compact 216-ball BGA footprint.

Frequently Asked Questions
What is the maximum CPU frequency and performance of STM32F746NGH6E?
STM32F746NGH6E runs at up to 216 MHz with an ARM Cortex-M7 core that delivers 340 DMIPS and 462 CoreMark. The FPU and DSP extensions allow single-cycle multiply-accumulate operations, making it suitable for real-time control and signal processing tasks requiring sub-microsecond response times.
Which display-interface designs can use STM32F746NGH6E to drive a color touchscreen without an external GPU?
STM32F746NGH6E integrates an LTDC parallel RGB display controller and a MIPI-DSI host controller, supporting panels up to 800x480 pixels at 24-bit color depth. The Chrom-ART DMA2D accelerator handles pixel blending and format conversion, allowing a 4.3-inch TFT LCD to run at 60 Hz refresh with 0 CPU cycles for fill operations.
How much on-chip RAM does STM32F746NGH6E provide and how is it partitioned?
STM32F746NGH6E provides 340 KB of on-chip SRAM: 64 KB ITCM, 128 KB DTCM accessible at 216 MHz zero-wait-state, and 48 KB of additional SRAM on AHB bus. An external SDRAM or NOR Flash can be connected via the FMC memory controller to expand to hundreds of megabytes for frame-buffer or data-logging applications.
When is STM32F746NGH6E preferred over STM32H743 for a cost-sensitive industrial HMI design?
STM32F746NGH6E is preferred when bill-of-material cost targets are tight and the application does not need the STM32H743 dual-core configuration or 480 MHz clock. At 216 MHz with 1 MB Flash and integrated Ethernet MAC, it delivers enough throughput for a 480x272 display HMI running FreeRTOS with 8 tasks at under $20 unit cost in 1 k quantities.
What package dimensions and PCB footprint area does the STM32F746NGH6E 216-ball BGA require?
The STM32F746NGH6E uses a 216-ball TFBGA package measuring 10 mm x 10 mm with a 0.5 mm ball pitch. The compact footprint allows placement in tight board areas while still exposing 168 GPIO pins, making it feasible for designs targeting less than 2500 mm² total PCB area.
