Product details

What this Cortex-M7 MCU brings to a display or connectivity design

The STM32H7B3NIH6: 2 MB of Flash and 1.4 MB of RAM on-chip. The 216-TFBGA package (13x13 mm) keeps the footprint compact.

Memory headroom and peripheral set for system integration

With 2 MB of Flash and 1.4 MB of RAM, this MCU handles firmware images that include a GUI stack, TCP/IP, and file system without needing external Flash or SRAM for many applications. The 116 I/Os and rich connectivity — USB OTG, CANbus, multiple SPI/I²C, SAI, and a camera interface — make it a natural fit for human-machine interfaces, industrial gateways, and embedded vision systems.
