The M7 handles the heavy floating-point or DSP workload — motor control algorithms, FFTs, audio processing — while the M4 runs the communications stack and peripheral housekeeping. That split avoids the timing headaches of a single core trying to service both a CANopen stack and a 16-bit ADC conversion sequence at full speed. With 2 MB of Flash and 1M x 8 of RAM, there is room for two firmware images plus a safe OTA staging area. The 97 GPIOs map comfortably onto a 144-LQFP package — enough for a parallel LCD, an external memory bus, and a handful of serial peripherals without multiplexing conflicts. Supply range is 1.62 V to 3.6 V. Internal oscillator eliminates external crystal for UART and I²C timing. ## Peripheral set for a connected controller Connectivity covers Ethernet, dual CAN, USB OTG, and multiple SPI/I²C/UART ports — enough for a Modbus TCP gateway with a local HMI and sensor bus. The 23-channel 16-bit ADC and dual 12-bit DAC handle analog front-end tasks like current sensing and setpoint generation without an external converter.","metaTitle":"ST STM32H755ZIT6U 32-Bit Dual-Core MCU, 240MHz/480MHz, 2MB Flash","metaDescription":"STMicroelectronics STM32H755ZIT6U dual-core ARM Cortex-M4/M7 MCU. 240MHz/480MHz speed, 2MB Flash, 1M x 8 RAM, 97 I/O, -40°C to 85°C.
