STMicroelectronics STM32F765ZGT6TR

Overview

STM32F765ZGT6TR from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with integrated FPU, delivering 462 DMIPS at 216 MHz. It features 2 MB dual-bank flash, 512 KB SRAM (including 128 KB data TCM), USB OTG HS/FS, MIPI DSI host controller, LCD-TFT controller, and hardware JPEG codec - enabling real-time graphics and multimedia processing in industrial HMI and embedded vision systems.

For engineers reviewing the STM32F765ZGT6TR datasheet, STM32F765ZGT6TR pinout, STM32F765ZGT6TR application, or STM32F765ZGT6TR equivalent, key selection criteria include dual-bank flash for robust firmware updates, 168 I/Os with 5 V tolerance, 216 MHz CPU clock, hardware-accelerated graphics (DMA2D + DSI), and Ethernet MAC with IEEE 1588v2 support.

Technical Context

The device implements a tightly coupled memory architecture with 16 KB I/D L1 cache and ART Accelerator, enabling zero-wait-state execution from flash. Its AXI-AHB bus matrix supports concurrent access to flash, SRAM, and peripherals, while the flexible memory controller (FMC) interfaces with SDRAM, NOR/NAND, and PSRAM.

It integrates three independent CAN 2.0B controllers, dual USB OTG (HS + FS), 10/100 Ethernet MAC with dedicated DMA and IEEE 1588v2 hardware timestamping, and a MIPI D-PHY compliant DSI host supporting up to 720p@30 Hz - making it suitable for deterministic industrial networking and display subsystems.

FAQ

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

The STM32F765ZGT6TR achieves 216 MHz via its Arm Cortex-M7 core with ART Accelerator and 16 KB L1 cache. This configuration enables zero-wait-state execution from flash memory. Stable operation requires proper decoupling of VCAP1/VCAP2 pins with 2.2 µF ceramic capacitors and adherence to the 1.7–3.6 V supply range per datasheet Section 6.3.1.

Does this MCU support hardware JPEG encoding and decoding?

Yes - the STM32F765ZGT6TR integrates a dedicated hardware JPEG codec supporting both encoding and decoding of baseline JPEG images. It operates independently of the CPU, handling up to 720p frames at 15 fps with minimal bandwidth impact on the AXI bus, as confirmed in Section 3.13 of DS11532 Rev 9.

What display interfaces does the STM32F765ZGT6TR support?

The MCU supports two complementary display interfaces: an RGB888 parallel LCD-TFT controller (up to XGA resolution) and a MIPI DSI host controller (up to 720p@30 Hz). Both operate concurrently; DSI uses dedicated D-PHY lanes (PH13–PH15, PI0–PI12), while LCD-TFT uses PE/PG/PI pins - detailed in Section 4 Pinouts and Section 3.10–3.47.

Is the STM32F765ZGT6TR pin-compatible with other STM32F7xx variants in LQFP144?

No - while STM32F765ZGT6TR shares the LQFP144 package with STM32F767ZGT6, pin functions differ significantly. For example, DSI host signals occupy PH13–PH15 on the F765 but are unused on the F767; LCD-TFT pins are also allocated differently. Always verify against the specific device's pin definition table (Table 11 in DS11532 Rev 9).
