It packs 2 MB of Flash and 1.4 MB of RAM, with 128 I/O lines and a rich peripheral set including camera interface, CANbus, multiple I²C/SPI/UART, USB OTG, and an LCD controller. The 176+25 UFBGA package (10x10 mm) and industrial temperature range (-40°C to 85°C) make it suited for high-end embedded control in factory automation, motor drives, and HMI panels that need a single-chip CPU with generous memory and connectivity. ## Memory and throughput — sizing the BOM fit The 280 MHz Cortex-M7 core delivers enough throughput for real-time control loops and graphics rendering on an external display. 2 MB of Flash accommodates a full firmware stack with a GUI library and communication protocol stack; 1.4 MB of RAM leaves headroom for large data buffers or a framebuffer without needing external SRAM. The 128 I/O count supports parallel buses and a wide sensor/actuator interface without a port expander. The lifecycle record shows an end-of-life (hot) status for this order code. While the manufacturer lists it as active, the EOL-hot flag signals that supply is tightening and a last-time-buy window may be closing. The 176+25 UFBGA (10x10 mm) is a surface-mount BGA. Requires a multi-layer PCB with microvias and controlled impedance for the high-speed peripherals. Connectivity spans camera interface, CANbus, EBI/EMI, HDMI-CEC, I²C, IrDA, LINbus, MDIO, MMC/SD/SDIO, PSSI, SAI, SPDIF, SPI, SWPMI, UART/USART, and USB OTG. The 24-channel 16-bit ADC and 3-channel 12-bit DAC cover analog sensor acquisition and control outputs without external converters.","metaTitle":"ST STM32H7B3IIK6 ARM Cortex-M7 MCU, 280MHz, 2MB Flash, 176+25 UFBGA","metaDescription":"STM32H7B3IIK6 32-bit MCU with 280MHz Cortex-M7 core, 2MB Flash, 1.4MB RAM, 128 I/O, -40°C to 85°C.
