This asymmetric compute arrangement lets the M7 handle heavy number-crunching — real-time control loops, audio processing, or Ethernet packet forwarding — while the M4 manages lower-priority housekeeping, communications, or sensor fusion without stalling the main thread. The 1 MB Flash and 1 MB RAM are balanced for firmware that keeps both cores fed, reducing the need for external memory in many designs. ## Connectivity and peripheral set — Ethernet, dual CAN, USB OTG, and more With built-in Ethernet, dual CAN interfaces, USB OTG, and QSPI, this MCU can serve as a single-chip gateway in industrial controllers, edge-compute nodes, or building-automation panels. Peripherals include multiple SPI, I²C, SAI, and SPDIF interfaces, plus an LCD controller and PWM timers for motor-drive or display applications. Housed in a 265-ball TFBGA (14x14 mm body), this part demands a multi-layer PCB with controlled-impedance routing for the high-speed interfaces. Supply voltage spans 1.62 V to 3.6 V, allowing single 3.3 V or 1.8 V rail designs with appropriate core LDO configuration. The base product number STM32H745 is shared across the family, simplifying BOM management if a different Flash/RAM or package variant is needed later.","metaTitle":"STM32H745XGH6 Dual-Core MCU, 480 MHz Cortex-M7 + 240 MHz M4","metaDescription":"STMicroelectronics STM32H745XGH6 32-bit dual-core ARM Cortex-M7 (480MHz) + M4 (240MHz), 1MB Flash, 1MB RAM, 168 I/O, Ethernet, CAN, USB OTG, -40°C to 85°C","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"240MHz, 480MHz","Series":"STM32H7","Package":"Tray","RAM Size":"1M x 8","Core Size":"32-Bit Dual-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, LINbus, MDIO, MMC/SD/SDIO, QSPI, SAI, SPDIF, SPI, SWPMI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"168","Core Processor":"ARM® Cortex®-M4/M7","Package / Case":"265-TFBGA","Product Status":"Active","Data Converters":"A/D 36x16b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32H745","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"240+25-TFBGA (14x14)","Voltage - Supply (Vcc/Vdd)":"1.62V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$16.7359","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9446ee013926cecb5fd61720b6182dfc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum clock speed of STM32H745XGH6?","answer":"The Cortex-M7 core runs at 480 MHz and the Cortex-M4 core runs at 240 MHz, giving asymmetric dual-core performance for compute-intensive and control tasks."},{"question":"Does STM32H745XGH6 have built-in Ethernet and CAN interfaces?","answer":"Yes, the connectivity set includes Ethernet MAC, dual CAN buses (CANbus), USB OTG, and QSPI, among others, making it suitable for industrial gateway and networked control applications."},{"question":"Is STM32H745XGH6 pin compatible with STM32H747?","answer":"The STM32H745 and STM32H747 share the same base product number and 265-TFBGA package, and they are pin-compatible across the STM32H74x/H75x dual-core family.
