STMicroelectronics STM32F756NGH6

Overview

STM32F756NGH6 from STMicroelectronics is a high-performance ARM Cortex-M7 microcontroller with FPU, 216 MHz max clock, 1 MB Flash, 320+16+4 KB RAM, hardware crypto acceleration (AES-128/192/256, SHA-1/2, HMAC), and integrated peripherals including dual CAN 2.0B, 10/100 Ethernet MAC, USB OTG HS/FS, LCD-TFT controller, and parallel camera interface - deployed in industrial HMI, medical imaging front-ends, and networked edge gateways.

For engineers reviewing the STM32F756NGH6 datasheet, STM32F756NGH6 pinout, STM32F756NGH6 application, or STM32F756NGH6 equivalent, key selection criteria include its 216 MHz Cortex-M7 core with L1 cache, dual-mode Quad-SPI support, Chrom-ART Accelerator™ for GUI rendering, IEEE 1588v2-capable Ethernet MAC, and TFBGA100 package with 100 I/Os rated to 108 MHz.

Technical Context

The STM32F756NGH6 implements a tightly coupled Arm Cortex-M7 core with 4 KB instruction and 4 KB data caches, ART Accelerator™ enabling zero-wait-state execution from Flash, and MPU for memory protection. It integrates dual-bank Flash with ECC, multiple TCM RAM banks (64 KB DTCM for real-time data, 16 KB ITCM for critical code), and a flexible AXI/AHB bus matrix supporting concurrent high-bandwidth access.

Its peripheral subsystem includes two independent SAI audio interfaces, SPDIFRX receiver, HDMI-CEC, SDMMC, dual CAN controllers, and a full-featured LCD-TFT controller with DMA2D (Chrom-ART) supporting XGA resolution - all synchronized via a multi-source clock tree with three PLLs (main, audio, SAI) and dedicated low-jitter oscillators.

Key Specifications

Pinout & Package

STM32F756NGH6 uses a TFBGA100 package (8 × 8 × 0.8 mm, 0.8 mm ball pitch) with 100 I/O balls, including 166 5 V-tolerant pins and support for multiple low-power modes (Sleep, Stop, Standby with VBAT).

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-performance MCU applications.

Compared with STM32F756NGH6, the STM32H743VIT6 delivers higher compute density and display capability but removes DCMI - making it unsuitable for camera-based edge inference. The STM32F767ZIT6 trades package compactness and SHA-2 support for I/O count and Flash size, better suited to wired industrial controllers than space-constrained imaging modules.

FAQ

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

The STM32F756NGH6 achieves 216 MHz maximum CPU frequency using its Arm Cortex-M7 core with ART Accelerator™ and 4 KB instruction/data caches. This configuration enables zero-wait-state execution from embedded Flash memory. The clock tree supports multiple PLL sources, including HSE (4–26 MHz) and HSI (16 MHz), with programmable dividers and multipliers to precisely generate the 216 MHz system clock while maintaining stability and jitter compliance.

Does STM32F756NGH6 support hardware-accelerated TLS?

Yes - the integrated cryptographic accelerator provides hardware AES-128/192/256, SHA-1/SHA-224/SHA-256, and HMAC computation, enabling efficient TLS 1.2 record encryption and certificate verification. While SHA-256 is supported, full TLS 1.3 readiness depends on software stack implementation, as the RNG and AES engines meet required entropy and throughput thresholds for handshake acceleration.

How does the LCD-TFT controller interface with external displays?

The LCD-TFT controller supports 8080/6800 8/16-bit parallel modes and RGB interface up to XGA (1024×768) resolution. It drives displays directly via PH13–PH15 (HSYNC/VSYNC/DCLK) and PI0–PI12 (24-bit RGB data), with programmable pixel clock (up to 65 MHz), polarity control, and built-in FIFO. Chrom-ART Accelerator™ (DMA2D) handles layer composition and alpha blending independently of the CPU, reducing display update latency.

What low-power modes are available and what peripherals remain active?

The STM32F756NGH6 supports Sleep, Stop, and Standby modes. In Stop mode (regulator ON/OFF configurable), RTC, LSE oscillator, backup SRAM, and LPTIM1 remain active; in Standby, only RTC, VBAT domain, and 4 KB backup SRAM operate. Wake-up sources include EXTI lines, RTC alarm, and USB activity. Current consumption drops to 3.4 µA (Standby with RTC) and 110 µA (Stop with regulator OFF), verified per DS10915 Rev 5 Section 6.3.32.
