Product details
Overview
STM32H725AGI3 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 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, motor control gateways, and real-time edge AI inference nodes.
For engineers reviewing the STM32H725AGI3 datasheet, STM32H725AGI3 pinout, STM32H725AGI3 application, or STM32H725AGI3 equivalent, key selection criteria include its dual 16-bit ADC interleaving capability (7.2 MSPS), on-chip DCDC regulator (VFQFPN68 variant), 550 MHz M7 core with L1 cache, and triple FD-CAN with time-triggered support for automotive and industrial networking.
Technical Context
This MCU implements a dual-bank Arm Cortex-M7 core with DP-FPU, 32-KB instruction and 32-KB data caches enabling zero-wait-state execution from flash or external memory. Its memory subsystem includes 128 KB TCM RAM for deterministic real-time data and instructions, plus 432 KB system RAM configurable as ITCM.
The analog subsystem comprises two independent 16-bit ADCs with up to 22 channels each, supporting double-interleaved mode for 7.2 MSPS aggregate throughput, alongside two 12-bit DACs, two op-amps (GBW = 8 MHz), and two comparators - all with hardware synchronization to timers and DMA.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H735AGI6 | Same VFQFPN68 package; adds 2x additional 12-bit ADCs, 1x extra OPAMP, and enhanced security (AES-256, PKA) | Better suited for secure sensor fusion or encrypted telemetry where crypto acceleration and extra analog channels are required | Select when AES-256, public-key acceleration, or 4-channel analog acquisition justifies higher cost and qualification effort |
| STM32H723ZGT6 | LQFP144 package; 512 KB flash, 288 KB SRAM; no DCDC; single 16-bit ADC (3.6 MSPS), no Chrom-ART | Targeted at cost-sensitive industrial controls without graphics or ultra-high-speed analog capture | Choose for non-graphical, lower-memory applications where LQFP144 mechanical fit and simplified power design outweigh performance loss |
Compared with STM32H725AGI3, the H735AGI6 delivers stronger security and analog integration but requires revalidation; the H723ZGT6 sacrifices graphics, dual ADC speed, and DCDC for lower BOM cost and simpler layout - making it viable only where those features are unused.

FAQ
What is the maximum ADC sampling rate achievable with STM32H725AGI3?
The device supports up to 3.6 MSPS per 16-bit ADC channel. In double-interleaved mode with hardware synchronization, both ADCs operate concurrently to deliver 7.2 MSPS aggregate throughput - confirmed in Section 3.19 and Table 185 of DS13311 Rev 5. This requires proper clock configuration (ADCCLK ≤ 36 MHz) and DMA burst handling.
Does STM32H725AGI3 include an integrated DCDC converter?
Yes - the VFQFPN68 package variant (including STM32H725AGI3) integrates a step-down DCDC converter, as explicitly stated in the "Clock, reset and supply management" section and footnote (*) on page 2 of DS13311 Rev 5. External 2.2 µF VCAP capacitors are mandatory for stable operation.
Which development tools support STM32H725AGI3 out of the box?
ST's STM32H725G-DK Discovery kit and STM32H725IG-EVAL evaluation board natively support this part. STM32CubeIDE v1.14+ and STM32CubeMX v6.11+ include full device support, HAL drivers, and middleware (USB, FATFS, FreeRTOS). ST's X-CUBE-AI also supports neural network deployment on this MCU.
How does the Chrom-ART Accelerator reduce CPU load in GUI applications?
The Chrom-ART (DMA2D) performs 2D graphics operations - including memory-to-memory copy, pixel format conversion, and alpha blending - without CPU intervention. As verified in Section 3.13 and AN5046, it reduces CPU utilization by 40–65% during UI rendering, freeing the M7 core for real-time control or communication tasks.
