That split lets you run the real-time control loop on the M7 and the communications stack or user interface on the M4 without a second chip. The 2 MB Flash and 1 MB RAM give enough headroom for motor-drive firmware with an Ethernet stack or a multi-protocol gateway application. Supply range is 1.62 V to 3.6 V.","metaTitle":"STM32H755IIT6 STM32H7 Dual-Core MCU, 240/480 MHz, 2 MB Flash","metaDescription":"STMicroelectronics STM32H755IIT6 32-bit dual-core ARM Cortex-M4/M7 MCU.
