STMicroelectronics STM32F745IGK6

Overview

STM32F745IGK6 from STMicroelectronics is a high-performance ARM Cortex-M7 microcontroller with FPU, 216 MHz max clock, 1 MB Flash, 320+16+4 KB 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 STM32F745IGK6 datasheet, STM32F745IGK6 pinout, STM32F745IGK6 application, or STM32F745IGK6 equivalent, key selection criteria include its 216 MHz Cortex-M7 core with ART Accelerator™, dual-mode Quad-SPI, Chrom-ART Accelerator™ for graphics acceleration, and IEEE 1588v2-capable Ethernet MAC with dedicated DMA.

Technical Context

The STM32F745IGK6 implements a tightly coupled Arm Cortex-M7 core with 4 KB instruction and 4 KB data L1 caches plus adaptive real-time accelerator (ART Accelerator™), enabling zero-wait-state execution from flash at 216 MHz. It integrates dual-bank Flash with ECC, TCM RAM (64 KB data + 16 KB instruction), and backup SRAM (4 KB) for RTC-critical data retention.

Its peripheral architecture features an AXI-AHB bus matrix supporting concurrent high-bandwidth access to Flash, SRAM, and peripherals; dual USB OTG controllers (one HS with ULPI support); and a full-featured LCD-TFT controller with DMA2D (Chrom-ART) for XGA resolution rendering - all synchronized via multiple PLLs including dedicated audio and LCD PLLs (PLLI2S/PLLSAI).

FAQ

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

The STM32F745IGK6 achieves a maximum operating frequency of 216 MHz using its Arm Cortex-M7 core with FPU, supported by the ART Accelerator™ and 4 KB instruction/data L1 caches. This configuration enables zero-wait-state execution from internal Flash memory, verified under 1.7–3.6 V supply and ambient temperatures up to 105°C per datasheet DS10916 Rev 5.

Does STM32F745IGK6 support hardware encryption or secure boot?

No - the STM32F745IGK6 does not integrate hardware cryptographic accelerators (AES/RSA/SHA) or secure boot ROM. Security relies on software-based implementations or external secure elements. For hardware security, ST recommends the STM32F76xxx or STM32H7xx families, which include TRNG, HASH, and PKA peripherals.

Can the Ethernet MAC operate without an external PHY?

No - the STM32F745IGK6 includes only a Media Access Controller (MAC) with IEEE 1588v2 hardware timestamping, but no integrated PHY. An external 10/100 PHY (e.g., LAN8742A) must be used with MII or RMII interface; the MAC connects via dedicated DMA and supports hardware checksum offload and jumbo frame handling.

What is the role of the Chrom-ART Accelerator™ in this MCU?

The Chrom-ART Accelerator™ (DMA2D) is a dedicated 2D graphics hardware engine that performs memory-to-memory copy, pixel format conversion, and alpha-blending independently of the CPU. It reduces CPU load in GUI applications by accelerating layer composition, font rendering, and image scaling - especially beneficial when driving XGA-resolution displays with dynamic content.
