STMicroelectronics STM32H725RGV3TR

Overview

STM32H725RGV3TR 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 (3.6 MSPS), Ethernet MAC, USB 2.0 HS/FS OTG, and three FD-CAN interfaces. It targets industrial HMI, motor control gateways, and real-time edge nodes requiring deterministic execution, graphics acceleration, and multi-protocol connectivity.

For engineers reviewing the STM32H725RGV3TR datasheet, STM32H725RGV3TR pinout, STM32H725RGV3TR application, or STM32H725RGV3TR equivalent, key selection considerations include its VFQFPN68 package, integrated DCDC regulator, dual TCM RAM architecture, and hardware accelerators (CORDIC, FMAC, Chrom-ART) for computationally intensive signal and graphics processing.

Technical Context

This MCU implements a dual-bank Arm Cortex-M7 core with 32-KB instruction and 32-KB data L1 caches, enabling zero-wait-state execution from flash or external memory. Its memory subsystem includes 128 KB data TCM RAM for time-critical variables and up to 256 KB instruction TCM RAM remapping capability - both with ECC protection.

The peripheral set integrates three FD-CAN controllers compliant with ISO 11898-1:2015, an Ethernet MAC with DMA, two SAI audio interfaces, and a 16-bit parallel slave synchronous interface (PSSI). Clock management supports multiple PLLs, including dedicated audio and USB PLLs, plus internal oscillators (64 MHz HSI, 48 MHz HSI48, 4 MHz CSI, 32 kHz LSI).

FAQ

Does STM32H725RGV3TR support TrustZone security?

No. STM32H725RGV3TR does not include Arm TrustZone technology. Security features are limited to ROP/PC-ROP, tamper detection, 96-bit unique ID, and hardware RNG. For TrustZone-enabled variants, consider the STM32H735 or STM32H745/755 families, which integrate secure execution environments and cryptographic accelerators.

What is the maximum operating temperature for this VFQFPN68 variant?

The STM32H725RGV3TR in VFQFPN68 package is rated for industrial temperature range: –40 °C to +85 °C ambient. Thermal performance is validated per JEDEC JESD51 standards with the exposed thermal pad soldered to PCB copper; junction temperature must remain ≤125 °C under worst-case power dissipation conditions.

Can the internal DCDC regulator power both core and I/O domains?

Yes. The embedded SMPS (step-down DCDC) supplies VDD_CORE and can be configured to also power VDDIO2 (I/O bank 2) in VFQFPN68 variants. This reduces external power components and improves efficiency - especially critical in battery-powered or thermally constrained designs where >85% conversion efficiency is required at 100–500 mA loads.

Is the 16-bit ADC capable of simultaneous sampling across all channels?

No. While the dual 16-bit ADCs support interleaved mode (7.2 MSPS aggregate), simultaneous sampling is limited to up to 22 channels across both converters - not all 22 channels sampled at identical timestamps. True simultaneous sampling requires external synchronization via ADCx_EXTSEL and precise trigger alignment, achievable only on selected channel pairs (e.g., ADC1_IN0/ADC2_IN0).
