That core speed, paired with 2 MB of Flash and 1.4 MB of on-chip RAM, puts it in the high-performance tier — capable of running a real-time control loop alongside a graphics stack without breaking a sweat. The 100-LQFP package gives you 80 I/O, enough for a parallel LCD interface, a camera sensor, and a CANbus node plus a handful of sensors. ## Connectivity and peripherals — what's on the die This MCU carries a full connectivity suite: CANbus, USB OTG, multiple SPI and I²C, UART/USART with LIN and IrDA support, plus an EBI/EMI interface for external memory or an Ethernet PHY. There's also a camera interface, an SPDIF transmitter, and an HDMI-CEC block — so it's equally at home in an HMI panel, a motor drive with a fieldbus gateway, or a medical device display controller. The data converter array includes 16 analog inputs with 16-bit resolution and three 12-bit DACs, covering analog feedback and sensor conditioning without an external ADC. ## Lifecycle reality — EOL hot, sourced through independent channel","metaTitle":"ST STM32H7B3VIT6Q ARM Cortex-M7 MCU, 280 MHz, 2 MB Flash","metaDescription":"STMicroelectronics STM32H7B3VIT6Q 32-bit MCU, ARM Cortex-M7 at 280 MHz, 2 MB Flash, 1.4 MB RAM, 80 I/O, industrial temp -40°C to 85°C.
