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.","metaTitle":"ST STM32H745ZIT6U 32-Bit Dual-Core MCU, 240/480 MHz, 2 MB Flash","metaDescription":"STMicroelectronics STM32H745ZIT6U dual-core Cortex-M4/M7 MCU. 2 MB Flash, 1 MB RAM, 97 I/O, -40 to 85°C, 144-LQFP.
