Product details
Overview
STM32F745ZGT6 from STMicroelectronics is a high-performance ARM® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, featuring 1 MB Flash, 320 KB + 16 KB + 4 KB RAM, USB OTG HS/FS, 10/100 Ethernet MAC, and dual CAN 2.0B interfaces - deployed in industrial HMI, medical imaging front-ends, and real-time motor control systems.
For engineers reviewing the STM32F745ZGT6 datasheet, STM32F745ZGT6 pinout, STM32F745ZGT6 application, or STM32F745ZGT6 equivalent, key selection considerations include LQFP144 package compatibility, TCM RAM allocation for deterministic execution, Chrom-ART Accelerator™ support for LCD-TFT graphics, IEEE 1588v2 hardware timestamping in Ethernet, and dual Quad-SPI interface capability for external code/data expansion.
Technical Context
The STM32F745ZGT6 integrates an Arm Cortex-M7 core with dual 4-KB L1 caches (instruction and data), ART Accelerator™ enabling zero-wait-state execution from Flash, and MPU for memory protection. It supports adaptive real-time execution via tightly coupled memory (TCM) - 64 KB data TCM for critical variables and 16 KB instruction TCM for latency-sensitive routines.
Its connectivity stack includes two independent USB controllers (FS OTG + HS/FS OTG with dedicated DMA), a full-featured 10/100 Ethernet MAC with MII/RMII and IEEE 1588v2 hardware support, and dual bxCAN 2.0B controllers with time-triggered communication capability - all synchronized to a multi-source clock system with PLLSAI for audio/LCD timing isolation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F767ZIT6 | Same Cortex-M7 core, 2 MB Flash, no Ethernet MAC, adds SDMMC v2.0 and additional SAI interface. | Better suited for multimedia-rich applications (e.g., audio streaming) where Ethernet is unnecessary and larger code footprint is required. | Select when external storage (eMMC/SD) and dual audio interfaces outweigh need for industrial Ethernet connectivity. |
| STM32H743ZIT6 | Cortex-M7 @ 480 MHz, dual-core option (M7+M4), 2 MB Flash, 1 MB SRAM, enhanced security (AES/HASH/PUF), no Chrom-ART but GPU-like MDMA. | Targeted at next-gen edge AI inference, secure boot-critical infrastructure, and higher-resolution display systems beyond XGA. | Choose for future-proofing with higher compute density, hardware crypto, and dual-core determinism - at cost premium and increased design complexity. |
Compared with STM32F767ZIT6, the STM32F745ZGT6 trades Flash capacity and SDMMC for integrated 10/100 Ethernet and Chrom-ART - making it optimal for real-time industrial networking with embedded GUIs. Against STM32H743ZIT6, it offers lower BOM cost and simpler toolchain support while retaining sufficient performance for most deterministic control tasks.

FAQ
What is the maximum operating frequency and how is it achieved?
The STM32F745ZGT6 achieves 216 MHz maximum CPU frequency using its internal PLL driven by either the 4–26 MHz HSE crystal oscillator or the 16 MHz HSI RC oscillator. The ART Accelerator™ and dual 4-KB L1 caches eliminate Flash wait states, enabling deterministic zero-cycle instruction fetch at full speed - verified under conditions specified in Section 6.3.11 of DS10916 Rev 5.
Does this MCU support hardware encryption or secure boot features?
The STM32F745ZGT6 does not integrate AES, HASH, or PUF hardware accelerators. It supports secure boot via external trusted execution environments or software-based signature verification using its True Random Number Generator (RNG) and CRC unit. For certified secure boot, ST recommends pairing with STSAFE-A110 or migrating to STM32H7-series MCUs with built-in cryptographic engines.
Can the LCD-TFT controller drive displays beyond XGA resolution?
No - the integrated LTDC (LCD-TFT Display Controller) is hardware-limited to XGA (1024×768) resolution per the datasheet specification in Section 3.10. Higher resolutions require external display controllers or migration to STM32H7-series MCUs with enhanced LTDC capabilities and higher pixel clock rates.
Is the Ethernet MAC compliant with IEEE 1588-2008 (PTP v2)?
Yes - the 10/100 Ethernet MAC includes full IEEE 1588v2 hardware timestamping support, with dedicated registers for PTP event message handling, fine-grained correction field adjustment, and sub-100 ns timestamp accuracy. This enables precise time synchronization in industrial Ethernet protocols like EtherCAT and PROFINET IRT when used with appropriate PHY and software stack.
