STMicroelectronics STM32F765NIH6TR

Overview

STM32F765NIH6TR from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with integrated FPU, delivering 462 DMIPS at 216 MHz, 2 MB flash (dual-bank), 512 KB SRAM (including 128 KB data TCM), and advanced peripherals including USB OTG HS/FS, MIPI DSI host controller, LCD-TFT controller, and hardware JPEG codec. It targets embedded graphics, industrial HMI, and real-time control systems requiring deterministic execution and rich connectivity.

For engineers reviewing the STM32F765NIH6TR datasheet, STM32F765NIH6TR pinout, STM32F765NIH6TR application, or STM32F765NIH6TR equivalent, key selection considerations include its dual-bank flash for seamless firmware updates, 216 MHz CPU clock with L1 cache enabling zero-wait-state execution, 168 I/Os with 5 V tolerance, and integrated Chrom-ART Accelerator for efficient GUI rendering - all in a TFBGA100 (8 × 8 mm) package.

Technical Context

The device implements a tightly coupled memory architecture with separate 16 KB instruction and data caches, ART Accelerator, and MPU to support deterministic real-time operation. Its AXI-AHB bus matrix enables concurrent access to flash, SRAM, and peripherals without contention.

It integrates dual-mode Quad-SPI, flexible external memory controller (FMC) supporting SDRAM/NOR/NAND, and three independent CAN 2.0B controllers - enabling robust industrial networking and external memory expansion for HMI applications requiring large frame buffers or firmware storage.

FAQ

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

The STM32F765NIH6TR achieves 216 MHz via its Arm Cortex-M7 core with ART Accelerator and dual 16 KB L1 caches (instruction and data). This configuration enables zero-wait-state execution from embedded flash memory, eliminating pipeline stalls. The clock tree supports PLL multiplication from internal or external oscillators (4–26 MHz), and voltage regulation is managed by an integrated 1.2 V regulator requiring external VCAP decoupling capacitors.

Does this MCU support true hardware JPEG encoding and decoding?

Yes - the STM32F765NIH6TR integrates a dedicated hardware JPEG codec capable of full encode and decode operations for baseline JPEG images up to 4096×4096 pixels. It operates independently of the CPU, using DMA for memory transfers, and supports YUV422/RGB565 input/output formats. This eliminates software JPEG library overhead and reduces CPU load in imaging applications such as medical displays or security camera UIs.

What display interfaces does the STM32F765NIH6TR natively support?

The MCU natively supports two complementary display interfaces: a parallel LCD-TFT controller driving XGA (1024×768) panels via 24-bit RGB + sync signals, and a MIPI DSI host controller supporting up to 720p@30 Hz. Both operate concurrently. The DSI interface uses dedicated high-speed differential lanes (CLKP/N, DAT0P/N, etc.), while the LCD-TFT interface uses standard GPIO-mapped parallel output - enabling flexible display architecture choices without external bridge ICs.

How many CAN interfaces does the STM32F765NIH6TR provide, and what version do they implement?

The STM32F765NIH6TR integrates three independent bxCAN 2.0B controllers, each supporting both standard (11-bit) and extended (29-bit) identifier frames, bit rates up to 1 Mbit/s, and programmable message filtering. All three CAN peripherals feature dedicated TX/RX mailboxes, automatic retransmission, and loopback/self-test modes - meeting requirements for redundant industrial networks or multi-node vehicle subsystems.
