STMicroelectronics STM32H725AGI3TR

Overview

STM32H725AGI3TR 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 low-latency processing and graphics acceleration.

For engineers reviewing the STM32H725AGI3TR datasheet, STM32H725AGI3TR pinout, STM32H725AGI3TR application, or STM32H725AGI3TR equivalent, key selection criteria include its VFQFPN68 package, integrated DC-DC regulator, dual TCM RAM architecture (128 KB data + up to 256 KB instruction), Chrom-ART accelerator for TFT-LCD rendering, and hardware math coprocessors (CORDIC/FMAC) for real-time signal processing.

Technical Context

The device implements a dual-bank Arm Cortex-M7 core with 32 KB instruction and 32 KB data L1 cache, enabling zero-wait-state execution from flash or external memory. Its memory subsystem includes ECC-protected SRAM partitioned into TCM (for time-critical code/data) and system RAM, plus flexible external memory controllers (FMC, Octo-SPI, SDIO).

Peripherals are organized around four DMA controllers-including MDMA with linked-list support-and a bus-interconnect matrix supporting concurrent high-bandwidth transfers. Real-time capability is reinforced by seventeen 16-bit timers (five low-power variants active in Stop mode), dual watchdogs, and subsecond-accurate RTC with hardware calendar.

FAQ

What is the maximum operating frequency and core configuration of the STM32H725AGI3TR?

The STM32H725AGI3TR features a single Arm Cortex-M7 core running at up to 550 MHz with double-precision floating-point unit (DP-FPU), memory protection unit (MPU), and 64 KB L1 cache (32 KB instruction + 32 KB data). It does not support dual-core operation; all performance metrics assume single-core execution with cache enabled and zero-wait-state flash access.

Does the STM32H725AGI3TR support external SDRAM, and what interface is used?

Yes, it supports external SDRAM up to 256 MB via the Flexible Memory Controller (FMC) with 24-bit data bus and dedicated SDRAM timing control. The FMC also supports NOR/NAND flash, PSRAM, and SRAM. Octo-SPI is available for XiP-capable serial flash but not for SDRAM expansion.

How many FD-CAN interfaces does the STM32H725AGI3TR have, and are they fully independent?

The STM32H725AGI3TR integrates three fully independent FD-CAN controllers (FDCAN1, FDCAN2, FDCAN3), each with dedicated message RAM, filters, and timestamping. All support ISO 11898-1:2015 CAN FD at up to 5 Mbit/s data phase and include TTCAN (time-triggered) mode for synchronized network operation.

Is the VFQFPN68 package of the STM32H725AGI3TR RoHS-compliant and ECOPACK2-certified?

Yes, the VFQFPN68 package is fully RoHS-compliant and certified to ST's ECOPACK2 environmental standard, which exceeds EU RoHS and REACH requirements. It uses lead-free matte tin plating, halogen-free molding compound, and conforms to JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) for surface-mount assembly.
