STMicroelectronics STM32F745VET6

Overview

STM32F745VET6 from STMicroelectronics is an ARM® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, featuring 512 KB flash, 320 KB SRAM (including 64 KB data TCM and 16 KB instruction TCM), dual USB OTG (FS/HS), 10/100 Ethernet MAC, LCD-TFT controller up to XGA, and triple 12-bit ADCs (2.4 MSPS). It targets high-performance embedded applications such as industrial HMI, motor control gateways, and networked edge devices requiring real-time graphics and connectivity.

For engineers reviewing the STM32F745VET6 datasheet, STM32F745VET6 pinout, STM32F745VET6 application, or STM32F745VET6 equivalent, key selection considerations include its 216 MHz Cortex-M7 core with L1 cache, dual USB OTG + Ethernet MAC with IEEE 1588v2 support, Chrom-ART Accelerator™ for DMA2D graphics offload, and 168 I/Os with 5 V tolerance - critical for deterministic real-time control and multi-interface system integration.

Technical Context

The STM32F745VET6 integrates an adaptive real-time accelerator (ART Accelerator™) enabling zero-wait-state execution from flash and external memories, alongside dual 4 KB L1 caches (instruction/data) to sustain full 216 MHz CPU throughput. Its AXI-AHB bus matrix supports concurrent high-bandwidth access across CPU, DMA, and peripherals including FMC, Quad-SPI, and LCD-TFT controller.

It implements a flexible clock system with multiple PLLs (main PLL, audio PLL, SAI PLL), dedicated RTC oscillator (32 kHz), and internal 16 MHz RC (±1% accuracy). Power management includes regulator ON/OFF modes, three low-power states (Sleep/Stop/Standby), and VBAT-supplied backup domain with 32×32-bit registers and 4 KB SRAM.

FAQ

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

The STM32F745VET6 achieves 216 MHz maximum CPU frequency using its internal main PLL with input from HSE (4–26 MHz) or HSI (16 MHz). The ART Accelerator™ and dual 4 KB L1 caches eliminate flash wait states, enabling sustained 216 MHz execution from embedded flash memory without performance throttling or external memory dependency.

Does STM32F745VET6 support hardware encryption or secure boot?

No - the STM32F745VET6 does not integrate hardware cryptographic accelerators (AES, PKA, HASH) or secure boot ROM. Security relies on software-based implementations or external secure elements. For hardware security, ST recommends the STM32F76xxx or STM32H7 series, which include TRNG, AES-256, and secure firmware install (SFI) features.

Can the Ethernet MAC operate without an external PHY?

No - the STM32F745VET6 includes only a Media Access Controller (MAC) with MII/RMII interfaces; it requires an external PHY chip (e.g., LAN8742A) for physical layer signaling. Unlike some STM32H7 variants, it lacks an integrated PHY, so board-level design must allocate space and routing for an external 10/100 PHY and associated magnetics.

What are the key differences between STM32F745 and STM32F746 in the same package?

The STM32F745VET6 supports dual Quad-SPI and 8080/6800 LCD interface only, while STM32F746VET6 adds RGB TFT interface and single Quad-SPI. Both share identical CPU, memory, Ethernet, USB, and ADC specs, but STM32F746 includes enhanced Chrom-ART capabilities and additional GPIO remapping for display timing control.
