This asymmetric architecture lets the M7 handle compute-intensive tasks — real-time control loops, signal processing, or graphics — while the M4 manages communication stacks, housekeeping, or low-power background routines. ## Connectivity and peripheral set — Ethernet, CAN, USB OTG on a single die The 97 I/Os in the 144-LQFP package give enough routing flexibility for a sensor-fusion board or a motor-drive controller with external encoder interfaces. The data converter block includes a 23-channel 16-bit ADC and a 2-channel 12-bit DAC, covering most analog front-end needs without an external converter. ## Temperature range and package — 144-LQFP for inspectable assembly The 144-LQFP package measures 20x20 mm with a 0.5 mm pitch — hand-solderable in rework, inspectable under a microscope, and compatible with standard QFP sockets for prototyping. Supply voltage spans 1.62 V to 3.6 V, allowing single 3.3 V or dual 1.8 V/3.3 V rail designs without an extra regulator. ## Lifecycle and sourcing posture Listed as Active by STMicroelectronics, so no last-time-buy pressure and no urgent need to qualify a second source. If a pin-compatible alternative is needed for dual-sourcing, the STM32H745 family shares the same footprint across density and temperature variants.","metaTitle":"STM32H745ZIT3 STM32H7 Dual-Core MCU, 240/480 MHz, 2 MB Flash","metaDescription":"STM32H745ZIT3 dual-core ARM Cortex-M4/M7 MCU from STMicroelectronics. 240/480 MHz speed, 2 MB Flash, 1 MB RAM, 144-LQFP.
