The STMicroelectronics STM32H725IGK6 is a high-performance 32-bit microcontroller based on the Arm Cortex-M7 core, designed for demanding embedded applications requiring high processing performance, extensive connectivity and advanced analog and graphics capabilities.
The Cortex-M7 CPU operates at frequencies up to 550MHz and integrates a double-precision floating-point unit (DP-FPU), DSP instructions, Memory Protection Unit (MPU), and separate 32KB instruction and 32KB data L1 caches. The architecture delivers up to approximately 1177 DMIPS for compute-intensive real-time applications.
The STM32H725IGK6 integrates 1MB of embedded Flash memory with ECC and a total of 564KB SRAM with ECC, including tightly coupled memory for deterministic real-time code and data execution. Flexible external memory support includes SRAM, PSRAM, SDRAM, NOR/NAND Flash and dual Octo-SPI interfaces with execute-in-place capability.
For graphics and HMI applications, the MCU incorporates the Chrom-ART Accelerator hardware graphics engine and an integrated LCD-TFT controller supporting resolutions up to XGA, reducing CPU workload in graphical user interface applications.
Communication interfaces include 100Mbps Ethernet with IEEE 1588 support, USB 2.0 High-Speed/Full-Speed Host/Device/OTG, three FDCAN interfaces, multiple USART/UART, SPI/I2S, I2C, SAI and SDMMC interfaces. These connectivity options make the device suitable for industrial networking, communication gateways and advanced embedded systems.
The analog subsystem includes two 16-bit ADCs, an additional 12-bit ADC, two 12-bit DACs, two operational amplifiers and two comparators. Hardware mathematical accelerators such as CORDIC and FMAC further improve performance for motor control, DSP and real-time signal-processing applications.
The device operates from an application supply of 1.62V to 3.6V and integrates both DCDC and LDO regulators. Low-power Sleep, Stop and Standby modes are available for applications requiring optimized energy consumption.
The specific STM32H725IGK6 ordering code is supplied in an industrial-grade UFBGA 176+25 package measuring 10 × 10 × 0.6mm with 0.65mm pitch and supports an operating temperature range of -40°C to +85°C.
