The M7 handles the heavy compute — real-time FFT, motor-control loops, or protocol stacks — while the M4 runs the housekeeping: sensor polling, display refresh, or low-power background tasks. Both cores share the 2 MB Flash and 1 MB SRAM through the bus matrix, so the memory budget needs to account for concurrent access patterns. ## Memory and peripherals — sizing the BOM With 2 MB of Flash and 1 MB of SRAM, this part sits in the high-density tier of the STM32H7 family — enough for a full TCP/IP stack, a graphics framebuffer, or dual-channel audio processing without external memory. The peripheral set includes dual CAN-FD, Ethernet MAC, USB OTG, eight UART/USART, six SPI, three I²C, and a parallel EBI/EMI bus for connecting external SRAM, NOR Flash, or an LCD controller. The 23-channel 16-bit ADC and two 12-bit DACs cover most analog front-end requirements. ## Package and assembly — 144-LQFP in production The 144-LQFP (20x20 mm) with 0.5 mm pitch is a standard surface-mount package that can be hand-soldered for prototyping and runs on any conventional SMT line.","metaTitle":"STM32H755ZIT6 Dual-Core MCU, 240/480MHz, 2MB Flash, 144-LQFP","metaDescription":"STMicroelectronics STM32H755ZIT6 dual-core ARM Cortex-M4/M7 MCU. 2MB Flash, 1MB SRAM, 240/480MHz, 144-LQFP.
