That split lets you dedicate the M7 to number-crunching — FFTs, motor-control loops, image processing — while the M4 handles real-time housekeeping like communication stacks and sensor polling. The 2 MB of Flash (2M x 8) and 1 MB of RAM (1M x 8) give you room for a dual-image firmware scheme without external memory for many designs. The 168 I/O pins and the peripheral set — Ethernet, CANbus, USB OTG, QSPI, SAI, and SPDIF — make this a natural fit for an industrial gateway or a high-end HMI panel that needs to talk to multiple fieldbuses and a display simultaneously. The internal oscillator and the brown-out detect/POR block reduce external BOM count. ## 169-UFBGA — package realities for layout and rework The 169-UFBGA package measures 7x7 mm.","metaTitle":"STMicroelectronics STM32H747AII6 MCU, 32-Bit Dual-Core","metaDescription":"STMicroelectronics STM32H747AII6 32-bit dual-core MCU with Cortex-M4 at 240MHz and Cortex-M7 at 480MHz, 2MB Flash, 1MB RAM, 169-UFBGA.
