Product details
Overview
STM32H725VGH3 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 HS/FS OTG, and Chrom-ART Accelerator. It targets real-time industrial HMI, motor control gateways, and edge AI inference nodes requiring deterministic execution and graphics acceleration.
For engineers reviewing the STM32H725VGH3 datasheet, STM32H725VGH3 pinout, STM32H725VGH3 application, or STM32H725VGH3 equivalent, key selection criteria include its dual-core-ready memory architecture (TCM RAM + system RAM remapping), hardware math accelerators (CORDIC/FMAC), 2×16-bit ADC interleaving capability, and VFQFPN68 package with 68-pin I/O mapping for space-constrained industrial controllers.
Technical Context
The STM32H725VGH3 implements a single Arm Cortex-M7 core with double-precision FPU, L1 cache (32 KB I-cache + 32 KB D-cache), and MPU - enabling zero-wait-state execution from flash and external memories. Its memory subsystem includes 128 KB data TCM RAM for time-critical variables and up to 256 KB system RAM remappable to instruction TCM for latency-sensitive code.
Real-time peripheral integration includes three FD-CAN controllers supporting ISO 11898-1:2015, an Ethernet MAC with DMA, two SAI audio interfaces, and dual 16-bit ADCs capable of 7.2 MSPS in interleaved mode. Clock management uses dual PLLs (main and audio) plus internal oscillators (64 MHz HSI, 48 MHz HSI48, 4 MHz CSI, 32 kHz LSI) and external crystal support (4–50 MHz HSE).

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance Cortex-M7 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H735VGT6 | Same VFQFPN68 package, identical peripherals, but adds AES/SHA crypto accelerators and 2 MB flash | Better suited for secure firmware updates and TLS stack offload in cloud-connected devices | Select when cryptographic acceleration and larger code space are required; otherwise, STM32H725VGH3 offers cost-optimized performance |
| STM32H723VGT6 | Omits Ethernet MAC, USB HS, and Chrom-ART; retains same CPU, memory, ADC, and FD-CAN capabilities | Targeted at cost-sensitive motor control or sensor fusion where networking and graphics are unnecessary | Choose for non-networked embedded control where reduced BOM cost and simpler layout justify feature reduction |
Compared with STM32H735VGT6, the STM32H725VGH3 trades crypto acceleration and extra flash for lower unit cost and identical real-time control capability; versus STM32H723VGT6, it adds critical Ethernet and USB HS connectivity for gateway-class designs without increasing package size.

FAQ
What is the maximum operating frequency and core type of the STM32H725VGH3?
The STM32H725VGH3 features a single Arm Cortex-M7 core running at up to 550 MHz with double-precision FPU, L1 instruction and data caches (32 KB each), and memory protection unit. It achieves 1177 DMIPS at 550 MHz (2.14 DMIPS/MHz) per Dhrystone 2.1 benchmark, with zero-wait-state execution from embedded flash due to cache architecture.
Does the STM32H725VGH3 support hardware encryption or secure boot?
No - the STM32H725VGH3 does not integrate AES, SHA, or PKA cryptographic accelerators, nor does it support hardware-based secure boot. Secure boot must be implemented in software using the embedded ROM bootloader and external trusted elements. For hardware crypto, consider the pin-compatible STM32H735VGT6 or STM32H753VIH6.
What are the supported debug interfaces and trace capabilities?
The STM32H725VGH3 supports both SWD and JTAG debug interfaces. It includes a 2 KB embedded trace buffer (ETB) for instruction and data trace, compatible with ARM CoreSight tools. Debug access is enabled via dedicated SWCLK/SWDIO pins (PA14/PA13) or JTAG pins (JTCK/JTMS/JTDI/JTDO/nTRST), with full support for real-time variable watch and flash programming.
How is the power supply configured for the embedded DCDC regulator?
The STM32H725VGH3's embedded SMPS operates in VFQFPN68 packages only and requires two 2.2 µF X7R ceramic capacitors on VCAP_1 and VCAP_2 pins. Input voltage range is 1.62–3.6 V; the DCDC outputs 1.25 V for core logic. External LDO mode is disabled in this variant - the DCDC must be used, and proper PCB layout (short traces, solid ground plane) is mandatory for stability.
