The 112 I/O and peripheral set include CANbus, USB OTG, a camera interface, and an LCD controller. The 144-LQFP (20x20 mm) package is a standard QFP footprint — hand-solderable, inspectable under a microscope, and reworkable with hot air. No hidden BGA voids, no X-ray inspection needed. The 112 I/O break out on four sides, so a four-layer board with a ground plane can route most signals without micro-vias. ## Supply range and power-on behaviour Operates from 1.62 V to 3.6 V. The built-in brown-out detect and POR eliminate the need for an external supervisor on most boards. ## Sourcing and lifecycle posture STMicroelectronics lists the STM32H7B3ZIT6 as Active (current production).","metaTitle":"STM32H7B3ZIT6 STM32H7 MCU, ARM Cortex-M7, 280MHz, 2MB Flash","metaDescription":"STM32H7B3ZIT6 32-bit ARM Cortex-M7 MCU at 280MHz, 2MB Flash, 1.4MB RAM, 112 I/O, 144-LQFP, -40°C to 85°C.
