STMicroelectronics STM32F745VEH6TR

Overview

STM32F745VEH6TR from STMicroelectronics is an ARM Cortex-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, featuring 512 KB flash, 320+16+4 KB SRAM (including TCM and backup RAM), USB OTG HS/FS, 10/100 Ethernet MAC, LCD-TFT controller, and dual CAN 2.0B interfaces - deployed in industrial HMI, medical imaging front-ends, and real-time motor control systems.

For engineers reviewing the STM32F745VEH6TR datasheet, STM32F745VEH6TR pinout, STM32F745VEH6TR application, or STM32F745VEH6TR equivalent, key selection criteria include LQFP100 package compatibility, 216 MHz real-time execution with ART Accelerator™ and L1 cache, triple 12-bit ADC (7.2 MSPS interleaved), Chrom-ART Accelerator™ for GUI rendering, and IEEE 1588v2 Ethernet support.

Technical Context

The device implements a dual-bus AXI-AHB matrix enabling concurrent access to flash, SRAM, and peripherals without contention. Its adaptive real-time accelerator (ART Accelerator™) with 4 KB instruction and 4 KB data caches enables zero-wait-state execution from embedded flash and external memories.

Clock architecture integrates multiple PLLs - main PLL for CPU/core clocks, audio PLL (PLLI2S) for SAI/I2S, and LCD PLL (PLLSAI) for display timing - all supporting fractional-N synthesis and spread-spectrum modulation for EMI reduction.

FAQ

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

The STM32F745VEH6TR achieves 216 MHz via its ARM Cortex-M7 core with ART Accelerator™ and dual 4 KB L1 caches (instruction and data). This eliminates wait states during flash execution, and the internal voltage regulator supports stable operation across 1.7–3.6 V supply range. External 4–26 MHz crystal or internal 16 MHz RC (1% accuracy) feeds the PLL to generate the system clock.

Does this MCU support hardware-accelerated graphics rendering?

Yes - it integrates the Chrom-ART Accelerator™ (DMA2D), a dedicated 2D graphics engine that performs memory-to-memory copy, pixel format conversion, and alpha blending without CPU intervention. It works in conjunction with the LCD-TFT controller to render UI elements at XGA resolution with minimal CPU load and consistent frame timing.

How does the Ethernet interface differ from standard MAC implementations?

This MCU features a 10/100 Ethernet MAC with dedicated DMA and full IEEE 1588v2 hardware support, including precise timestamping of PTP event messages and hardware correction for network delay asymmetry. Unlike software-based PTP stacks, this enables sub-microsecond time synchronization accuracy required in industrial motion control and power grid automation.

Can the STM32F745VEH6TR operate in low-power modes while maintaining real-time functionality?

Yes - it supports Sleep, Stop, and Standby modes with selective peripheral retention. In Stop mode, the low-power timer (LPTIM1) continues running, and up to 164 GPIOs retain interrupt capability. The backup domain (RTC, 32×32-bit registers, 4 KB SRAM) remains powered by VBAT, enabling wake-up events and calendar maintenance with typical current draw below 2.5 µA.
