Product details

Overview

STM32H725IGK3 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller operating at up to 550 MHz, featuring 1 MB embedded flash with ECC, 564 KB SRAM (all with ECC), dual 16-bit ADCs delivering up to 3.6 MSPS, and triple FD-CAN interfaces. It integrates Ethernet MAC, USB 2.0 HS/FS OTG, Chrom-ART Accelerator, and LCD-TFT controller - deployed in industrial HMI gateways requiring real-time graphics, deterministic communication, and secure firmware execution.

For engineers reviewing the STM32H725IGK3 datasheet, STM32H725IGK3 pinout, STM32H725IGK3 application, or STM32H725IGK3 equivalent, key selection considerations include its VFQFPN68 package footprint, dual-core-ready memory architecture (TCM RAM + system RAM remapping), 24-timer peripheral set with low-power timers active in Stop mode, and hardware-accelerated CORDIC/FMAC for motor control and signal processing.

Technical Context

The STM32H725IGK3 implements a dual-bank Arm Cortex-M7 core with DP-FPU, L1 instruction/data caches (32 KB each), 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 as instruction TCM RAM.

It features three independent FD-CAN controllers compliant with ISO 11898-1:2015, supporting bit rates up to 5 Mbps and protocol-level time-triggered (TT-CAN) operation on FDCAN1. The analog subsystem integrates two 16-bit ADCs with interleaved mode (7.2 MSPS), two 12-bit DACs, two op-amps (GBW = 8 MHz), and two comparators - all accessible under real-time OS scheduling with dedicated MDMA and dual-port DMA channels.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-performance MCU applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32H735IGK6	Same VFQFPN68 package; adds cryptographic accelerator (AES-256, PKA, HASH), higher max frequency (600 MHz), and 2 MB flash	Required for TLS 1.3 handshake acceleration or secure boot with public-key verification	Select when cryptographic offload or extended firmware storage is mandatory; otherwise, STM32H725IGK3 offers lower cost and identical peripheral set
STM32H723ZGT6	LQFP144 package (20×20 mm); same core/peripherals but no Ethernet MAC, reduced SRAM (512 KB), and no Chrom-ART	Suitable for non-networked, cost-sensitive HMI where display resolution ≤ WVGA suffices	Choose for legacy PCB compatibility with LQFP footprint or when Ethernet and advanced graphics are unnecessary

Compared with STM32H735IGK6, the STM32H725IGK3 trades cryptographic acceleration and flash size for lower unit cost and identical real-time performance; versus STM32H723ZGT6, it delivers Ethernet connectivity and full XGA graphics support in the same compact VFQFPN68 form factor - making it optimal for space-constrained, connected edge devices.

FAQ

What is the maximum operating frequency of the STM32H725IGK3?

The STM32H725IGK3 operates at a maximum CPU frequency of 550 MHz, achieved using the Arm Cortex-M7 core with dual-issue superscalar pipeline and L1 cache. This frequency is sustained across industrial temperature range (–40°C to +85°C) when powered within the specified 1.62–3.6 V supply range and with proper decoupling and thermal design per ST's AN5023 guidelines.

Does the STM32H725IGK3 support hardware encryption?

No, the STM32H725IGK3 does not integrate a dedicated cryptographic accelerator. It lacks AES, PKA, or HASH engines found in the STM32H73x series. Secure operations must be implemented in software or via external secure elements; however, it does provide ROP/PC-ROP, tamper detection, and ECC on all memory to support basic firmware integrity protection.

Which development tools are officially supported for STM32H725IGK3 firmware development?

ST provides full support through STM32CubeIDE (based on Eclipse), STM32CubeMX for initialization code generation, and STM32CubeH7 HAL/LL libraries. Debugging is enabled via SWD or JTAG using ST-LINK/V3, and evaluation is validated on the STM32H725G-DK discovery kit - which shares the same VFQFPN68 package and core peripherals as the IGK3 variant.

Can the STM32H725IGK3 drive an RGB888 1024×768 display directly?

Yes, the integrated LCD-TFT controller (LTDC) supports RGB888 format at XGA resolution (1024×768) with up to 24-bit color depth and hardware layer blending. It requires external SDRAM for frame buffer storage (via FMC) and compatible display timing signals - verified in ST's AN5119 application note using the STM32H725G-DK board with a 7-inch RGB panel.
