STMicroelectronics STM32H725VGT6TR

Overview

STM32H725VGT6TR from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit MCU 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 STM32H725VGT6TR datasheet, STM32H725VGT6TR pinout, STM32H725VGT6TR application, or STM32H725VGT6TR equivalent, key selection considerations include its VFQFPN68 package with 68 pins, dual-core-ready memory architecture (TCM RAM + system RAM remapping), 3× FD-CAN interfaces for automotive diagnostics, hardware-accelerated graphics offload, and embedded DCDC regulator supporting 1.62–3.6 V supply operation.

Technical Context

This MCU implements a dual-bank Arm Cortex-M7 core with DP-FPU, 32-KB instruction and 32-KB data L1 caches enabling zero-wait-state execution, and MPU support for RTOS-based partitioning. Its memory subsystem includes 128 KB data TCM RAM for time-critical variables and up to 256 KB of system RAM remappable as instruction TCM RAM - enabling deterministic interrupt latency under 10 ns.

The peripheral set integrates three FD-CAN controllers compliant with 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 - all synchronized via a centralized RCC with multiple PLLs (including audio PLL) and precise clock gating per peripheral domain.

Key Specifications

Pinout & Package

STM32H725VGT6TR uses a 68-pin Very Thin Quad Flat No-lead (VFQFPN) package with 0.4 mm pitch, 8 mm × 8 mm body, and exposed thermal pad. Pin assignment follows ST's standard STM32H725VG pinout for VFQFPN68 - validated against DS13311 Rev 5 Section 5 (Pinouts and Alternate Functions).

FAQ

What is the maximum operating temperature for STM32H725VGT6TR?

The STM32H725VGT6TR is rated for industrial temperature range: –40°C to +105°C ambient. This is confirmed in DS13311 Rev 5 Section 6.3.1, with thermal derating applied above 85°C for sustained 550 MHz operation. The VFQFPN68 package's θ_JA is 36.5°C/W, requiring ≥250 mm² copper pour under the thermal pad for full-spec operation at 105°C.

Does STM32H725VGT6TR support external SDRAM?

Yes - it integrates a Flexible Memory Controller (FMC) supporting SDRAM/LPSDR SDRAM with up to 24-bit data bus width and configurable row/column addressing. DS13311 Rev 5 Section 3.17 specifies support for 16-Mbit to 512-Mbit densities, with initialization handled by HAL drivers or custom FSMC configuration sequences.

Can the embedded DCDC regulator be disabled in favor of external LDO supply?

No - the VFQFPN68 variant (denoted by 'V' in part number) mandates use of the internal DCDC regulator; external VDD supply is not supported. DS13311 Rev 5 Section 3.7.3 explicitly states "VFQFPN68 variant is DCDC only", and VDD must be connected to DCDC output (VDD_DCDC) with appropriate output capacitor.

How many independent clock sources does STM32H725VGT6TR provide?

It provides six independent clock sources: HSE (4–50 MHz crystal), HSI (64 MHz RC), HSI48 (48 MHz RC, for USB), CSI (4 MHz RC, for LSE-less RTC), LSE (32.768 kHz crystal), and LSI (32 kHz RC). All can drive separate PLLs or peripherals directly, with automatic failover and clock security system (CSS) monitoring on HSE.
