The STM32H7B3VIH6: The 80 I/O lines in a 100-ball TFBGA package give you room for a parallel LCD, an external bus, and a handful of sensors or actuators. 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.
Lifecycle and supply posture
The base product number is STM32H7B3, so any PCN or EOL notification from ST will reference that root.
