Supply range runs from 1.62 V to 3.6 V.
Peripheral set — what connects without glue
The connectivity block is dense: Camera interface, CANbus, dual USB OTG, Ethernet (through EBI/EMI), multiple SPI/I²C/UART, SAI for audio, SPDIF, and an MDIO for PHY management. The 16-channel 16-bit ADC and three 12-bit DACs cover analog front-end work. Brown-out detection, POR, and a programmable watchdog are built in — no external supervisor needed for most industrial or consumer designs.
Package and temperature — layout and environment
Storage temperature exceeds this range — the part can sit in a hot warehouse or on a rework station without damage, but running it above 85°C ambient requires derating the core clock or reducing the peripheral load.
The base product number is STM32H7B3, so any PCN or EOL notification from ST will reference that root.
