Product details

480 MHz Cortex-M7 with 2 MB on-chip flash

The STM32H743XIH6 is an STM32H7 series microcontroller built around a single ARM Cortex-M7 core running at 480 MHz — the highest clock speed in the STM32 portfolio. This puts it in the class of MCUs that can handle real-time control loops, motor FOC, and DSP filter chains without a separate DSP coprocessor. For applications that stream sensor data or run a TCP/IP stack with a GUI, this memory budget often eliminates the need for external parallel SRAM or serial flash.

Connectivity and analog front-end for industrial gateways

This makes the STM32H743XIH6 a natural fit for a programmable logic controller or an industrial communication gateway that bridges fieldbus and Ethernet. On the analog side, 36 channels of 16-bit ADC and two 12-bit DAC channels handle multi-channel sensor acquisition and analog output generation. The 168 GPIOs in the 265-ball TFBGA package give enough headroom for parallel address/data buses, external memory interfaces, and custom peripheral muxing.

The base product number is STM32H743 — this is the high-performance member of the STM32H7 family. Operating temperature range is -40°C to 85°C (TA), suitable for factory-floor, outdoor enclosure, and HVAC deployments.

Frequently asked questions

What is the speed rating of STM32H743XIH6?

The listed maximum speed is 480 MHz for the ARM Cortex-M7 core. This is the highest clock frequency available in the STM32 portfolio and supports real-time control, DSP, and floating-point operations without an external co-processor.
