Product details

Dual-core architecture — what the speed split means for your firmware

The STM32H745ZIT6U pairs a Cortex-M4 running at 240 MHz with a Cortex-M7 at 480 MHz on the same die. That lets you offload real-time control loops (motor commutation, sensor polling) to the M4 while the M7 crunches DSP or floating-point workloads. The 2 MB of Flash and 1 MB of RAM give both cores room for their own code and data without fighting over external memory.

144-LQFP — rework-friendly footprint

The 144-LQFP package measures 20x20 mm. 97 I/O are brought out for CANbus, Ethernet, USB OTG, SPI, and I²C.

Supply range is 1.62 V to 3.6 V.

That means it is in normal production with no last-time-buy or end-of-life notice.

Frequently asked questions

Is STM32H745ZIT6U obsolete or end-of-life?

No — the STM32H745ZIT6U is listed as Active with no end-of-life notice.

What is STM32H745ZIT6U's listed speed?

The Cortex-M4 core runs at 240 MHz and the Cortex-M7 core at 480 MHz.

How many I/O pins does STM32H745ZIT6U have?

97 I/O are available on the 144-LQFP package.

What is the difference between STM32H745 and STM32H755?

The STM32H755 adds a second Cortex-M7 core for symmetric multiprocessing; the STM32H745 has one M7 and one M4. Pinout and peripherals are otherwise similar.

Is STM32H745ZIT6U suitable for real-time industrial control?

Yes — the dual-core architecture with a 240 MHz M4 dedicated to real-time loops and the -40°C to 85°C temperature range make it a fit for motor drives, PLCs, and factory automation.
