That speed split is deliberate: the M7 handles number-crunching and real-time control loops at full throttle, while the M4 runs communications stacks or housekeeping tasks without starving the M7's cache. Both cores share 2 MB of Flash and 1 MB of RAM, so firmware teams need to partition code and data carefully — the memory map is unified, but contention on the bus arbiter is real if both cores hammer the same peripheral simultaneously. ## Peripheral set and connectivity — what is on the bus 168 I/O lines bring out a rich peripheral set: dual CANbus, Ethernet MAC, USB OTG, multiple SPI/I²C/UART, plus an EBI/EMI for external memory or FPGA glue. The 36-channel 16-bit ADC and dual 12-bit DAC cover multi-sensor acquisition and analog output without external converters — a board-space and BOM consolidation factor for mixed-signal designs.","metaTitle":"ST STM32H757XIH6U Dual-Core MCU, 240/480 MHz, 2 MB Flash, 265-TFBGA","metaDescription":"STMicroelectronics STM32H757XIH6U 32-bit dual-core ARM Cortex-M4/M7 MCU. 240 MHz / 480 MHz, 2 MB Flash, 1 MB RAM, 168 I/O, -40 to 85°C.
