The RAM is generous enough for dual-bank OTA updates or audio processing pipelines. If your application needs more than 1.4 MB of working memory, you will need an external SDRAM or SRAM — the EBI/EMI interface supports that. ## Package and rework — 144-LQFP, no BGA fuss The 144-LQFP package (20x20 mm body) is a standard QFP with 0.5 mm pitch. It is reworkable with a basic soldering iron and flux — no BGA reball or hot-air station required. The leads are visible for inspection, which helps in field repairs or low-volume assembly. MSL 3 out of the bag per the STM32H7 family; bake before reflow if the moisture barrier bag has been open past the floor-life window. The base product number is STM32H7B3, and the series is STM32H7, so future density or package variants are available if your BOM needs to scale.","metaTitle":"STM32H7B3ZIT6Q STM32H7 ARM Cortex-M7 MCU, 280 MHz","metaDescription":"STMicroelectronics STM32H7B3ZIT6Q: 32-bit ARM Cortex-M7 at 280 MHz, 2 MB Flash, 1.4 MB RAM, 112 I/O, -40°C to 85°C, 144-LQFP.
