STMicroelectronics STM32H725VGT3TR

Overview

STM32H725VGT3TR from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller operating at up to 550 MHz, featuring 1 MB flash with ECC, 564 KB SRAM (all with ECC), dual 16-bit ADCs delivering up to 3.6 MSPS, and integrated FD-CAN, Ethernet MAC, USB 2.0 HS/FS OTG, and Chrom-ART Accelerator - deployed in industrial HMI controllers requiring real-time graphics, deterministic communication, and secure firmware execution.

For engineers reviewing the STM32H725VGT3TR datasheet, STM32H725VGT3TR pinout, STM32H725VGT3TR application, or STM32H725VGT3TR equivalent, key selection considerations include L1 cache configuration (32 KB I-cache + 32 KB D-cache), VFQFPN68 package thermal performance, dual ADC interleaving capability, embedded DCDC regulator support, and FD-CAN timing compliance for automotive-grade networking.

Technical Context

The device implements a dual-bank Arm Cortex-M7 core with double-precision FPU, MPU, and tightly coupled memory architecture - enabling zero-wait-state execution from flash via 32-KB instruction and data caches. It integrates a dedicated MDMA controller with linked-list support and two dual-port DMAs with FIFO, offloading CPU-intensive data movement across peripherals including Octo-SPI, SDMMC, and Ethernet.

Its analog subsystem includes two independent 16-bit ADCs (22-channel total, 7.2 MSPS in interleaved mode), two 12-bit DACs, two operational amplifiers (GBW = 8 MHz), and two comparators - all supported by hardware-accelerated DFSDM filters and a digital temperature sensor with ±1.5°C accuracy over –40°C to +125°C.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency and core type of the STM32H725VGT3TR?

The STM32H725VGT3TR features an Arm Cortex-M7 core with double-precision FPU, rated for up to 550 MHz operation. It achieves 1177 DMIPS at this frequency with 2.14 DMIPS/MHz efficiency (Dhrystone 2.1). The core includes memory protection unit (MPU), L1 cache (32 KB instruction + 32 KB data), and supports zero-wait-state execution from embedded flash memory.

Does the STM32H725VGT3TR support hardware-accelerated graphics rendering?

Yes - it integrates the Chrom-ART Accelerator (DMA2D), a dedicated 2D graphics hardware engine that performs copy, fill, blending, and pixel format conversion without CPU intervention. This enables efficient rendering of layered GUIs on TFT-LCD panels up to XGA resolution (1024 × 768), reducing CPU load by up to 40% during display updates in real-time HMI applications.

What are the key analog capabilities of this MCU?

The device integrates two independent 16-bit ADCs supporting up to 3.6 MSPS each (7.2 MSPS in interleaved mode), 12-bit DACs, two rail-to-rail operational amplifiers (GBW = 8 MHz), two ultra-low-power comparators, and a digital temperature sensor (±1.5°C accuracy). All SRAM and flash include ECC, and ADC/DAC paths support hardware-calibrated offset/gain correction for precision measurement systems.

Which FD-CAN and Ethernet features are implemented in the STM32H725VGT3TR?

It includes three fully independent FD-CAN controllers compliant with ISO 11898-1:2015, supporting data rates up to 5 Mbit/s in FD mode and legacy CAN 2.0B. It also integrates a full Ethernet MAC with DMA controller, supporting RMII interface and IEEE 1588 timestamping - enabling standalone industrial Ethernet nodes without external PHY for basic TCP/IP or EtherCAT slave implementations.
