The RAM is enough to run dual display buffers at 480x272 with 16-bit colour without thrashing external memory. The data converter complement — 36 channels of 16-bit ADC and two 12-bit DACs — supports multi-axis sensor acquisition or closed-loop analog control without external ADCs. ## 144-LQFP package — layout and thermal considerations Housed in a 144-LQFP with a 20x20 mm body, this is a hand-solderable, inspectable package that suits two-layer or four-layer boards. ## Lifecycle status — what 'Preliminary' means for your BOM This part carries a 'Preliminary' product status, which indicates it is in the early production ramp phase. That means datasheet values are subject to change as characterization completes, and the part may not yet be fully released for volume production.","metaTitle":"STM32H743ZIT6U STM32H7 MCU, ARM Cortex-M7 480MHz, 2MB Flash","metaDescription":"STM32H743ZIT6U 32-bit ARM Cortex-M7 MCU at 480MHz, 2MB Flash, 1MB RAM, 144-LQFP.
