STMicroelectronics STM32F765VGH6

Overview

STM32F765VGH6 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with integrated FPU, delivering 462 DMIPS at 216 MHz, 2 MB dual-bank flash, 512 KB SRAM (including 128 KB data TCM), and advanced peripherals including USB OTG HS/FS, MIPI DSI host controller, LCD-TFT controller, and triple CAN 2.0B interfaces - deployed in industrial HMI, medical imaging front-ends, and real-time motor control systems.

For engineers reviewing the STM32F765VGH6 datasheet, STM32F765VGH6 pinout, STM32F765VGH6 application, or STM32F765VGH6 equivalent, key selection criteria include its 216 MHz Cortex-M7 core with L1 cache, dual-bank flash for seamless firmware updates, 168 I/Os with 5 V tolerance, hardware JPEG codec, and support for external SDRAM/NAND via flexible memory controller.

Technical Context

The device implements a tightly coupled memory architecture with separate 16 KB I/D caches, ART Accelerator enabling zero-wait-state execution from flash, and dual-bank flash allowing concurrent read-while-write operations. Its AXI-AHB bus matrix supports high-bandwidth parallel access to internal SRAM, external memories, and peripherals.

Real-time capability is enhanced by 128 KB data TCM RAM for time-critical variables and 16 KB instruction TCM RAM for latency-sensitive routines, while the Chrom-ART Accelerator (DMA2D) offloads 2D graphics composition and the hardware JPEG codec enables real-time image encoding/decoding without CPU intervention.

FAQ

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

The STM32F765VGH6 achieves 216 MHz via its Arm Cortex-M7 core with ART Accelerator and 16 KB I/D caches, enabling zero-wait-state execution from flash. This requires proper configuration of the flash latency (3WS at 216 MHz), VCAP capacitor placement (2.2 µF each), and stable 1.2 V core supply regulated by the internal LDO. External crystal oscillator must be 4–26 MHz, with PLL multiplication set accordingly.

Does STM32F765VGH6 support external SDRAM, and what interface is used?

Yes, it supports external SDRAM up to 256 MB using the Flexible Memory Controller (FMC) with 32-bit data bus and dedicated SDRAM command/control signals (CK, CKE, CS, RAS, CAS, WE, BA0–BA2). The FMC complies with JEDEC standards and supports auto-refresh, self-refresh, and burst modes - validated in DS11532 Rev 9 Section 3.8 and Table 12.

How many I/O pins are 5 V-tolerant, and which banks support this feature?

STM32F765VGH6 provides up to 166 5 V-tolerant I/Os across GPIO ports A through I, excluding analog-only pins (e.g., VREF+, VREF−) and certain debug pins (SWDIO, SWCLK). Tolerance is inherent to the silicon process and requires no external components - confirmed in DS11532 Rev 9 Section 2.1 and Table 11 pin definitions.

What debugging interfaces does STM32F765VGH6 support, and are they accessible in all low-power modes?

It supports SWD and JTAG via dedicated pins (PA13/SWDIO, PA14/SWCLK, and optional JTCK/JTDI/JTDO/TRST), with SWD being the default and recommended interface. Debug is disabled in Stop and Standby modes but remains active in Sleep mode. The Cortex-M7 Trace Macrocell™ enables real-time instruction tracing when powered - detailed in DS11532 Rev 9 Section 3.45 and 3.46.
