The 132-WLCSP package (4.57x4.37 mm) saves board area but requires an SMT line with fine-pitch capability — this is not a hand-solderable part. ## Peripheral set and connectivity The 17x16-bit ADC and 3x12-bit DAC channels cover analog front-end needs without an external converter. Operates from 1.62 V to 3.6 V, covering both 1.8 V and 3.3 V logic rails. An internal oscillator reduces external BOM count.","metaTitle":"STM32H7B3QIY6QTR STM32H7 ARM Cortex-M7 MCU, 280 MHz","metaDescription":"STMicroelectronics STM32H7B3QIY6QTR 32-bit ARM Cortex-M7 MCU at 280 MHz with 2 MB Flash and 1.4 MB RAM.
