STM32H745XIH6 - Dual-Core 480MHz MCU | STMicroelectronics
MPN： STM32H745XIH6 ✓ 啟用中STM32H745XIH6 概覽
A dual-core microcontroller is an integrated circuit containing two independently programmable processor cores within one package. The Cortex-M7 core handles demanding control loops, graphics acceleration, communications, and digital signal processing, while the Cortex-M4 core can execute supporting tasks concurrently. This heterogeneous architecture belongs to the broader embedded-controller and semiconductor hierarchy, helping improve responsiveness without requiring two discrete microcontrollers.
The STM32H745XIH6 provides up to 2 MB of flash for firmware and 2 MB of SRAM, including 1 MB of RAM stated in the manufacturer family datasheet. Its communication and analog interface count reaches 46. The family also includes an SMPS capability. A Cortex-M7 operating at 480 MHz supports computationally intensive applications, while the Cortex-M4 operating at 240 MHz remains suitable for real-time peripheral management and low-latency control tasks.
Typical applications include industrial automation controllers, high-speed data acquisition systems, audio and DSP platforms, network-connected embedded equipment, and motor-control products. The two cores allow compute-intensive work and supervisory logic to run concurrently, potentially reducing synchronization complexity when software is partitioned correctly. The 14 x 14 mm TFBGA package also supports dense board layouts, although its fine pitch requires careful PCB construction and inspection.
Designers should verify all 265 package terminals against the manufacturer pin-description table before routing the PCB. Power, ground, decoupling, high-speed interfaces, and exposed-pad connections require close attention because the package combines advanced processing performance with a large pin count. Firmware and peripheral assignments should also account for the separate core resources rather than assuming that both cores support every identical peripheral instance.
This product overview combines the manufacturer family specifications, package information, application guidance, and practical drop-in comparison points. It is designed to help engineers evaluate performance, memory, connectivity, and board-level implementation requirements before integrating the STM32H745XIH6 into a new embedded platform.

典型應用
STM32H745XIH6 適用於 6 應用s: Industrial Automation Controller, High-Speed Data Acquisition, Audio and DSP Platform, Networked Embedded Equipment, Motor Drive and Power Control, Human-Machine Interface Controller.
Industrial Automation Controller
The STM32H745XIH6 fits industrial automation controllers that must combine fast control calculations with concurrent supervisory logic. Its Cortex-M7 core operates up to 480 MHz for motion control, filtering, or high-rate digital signal processing, while the Cortex-M4 core reaches 240 MHz for communication stacks and peripheral servicing. The family provides 46 communication and analog interfaces, allowing the design to consolidate functions that might otherwise require several controllers. Use the larger core for deterministic control and the secondary core for diagnostics or background protocol work, while confirming temperature grade, power sequencing, and safety requirements for the deployed equipment.
推薦
High-Speed Data Acquisition
The STM32H745XIH6 is well suited to data-acquisition equipment that must sample, process, and move information without relying on a separate processor. The 480 MHz Cortex-M7 can execute real-time digital filtering and analysis, while the 240 MHz Cortex-M4 can handle buffering, communications, or control tasks in parallel. Up to 2 MB of flash supports firmware and configuration tables, and the 1 MB RAM allocation provides working space for acquisition pipelines. The 46 communication and analog interfaces offer extensive connection options, but designers should confirm channel counts, converter synchronization requirements, and analog performance against the family datasheet.
推薦
Audio and DSP Platform
The STM32H745XIH6 supports audio and digital signal-processing platforms that benefit from a high-performance Cortex-M7 and a concurrent Cortex-M4. The M7 can process demanding audio algorithms at up to 480 MHz, including filtering or real-time transformations, while the M4 can manage low-latency controls and interface activity at up to 240 MHz. Its 1 MB RAM and 2 MB flash provide a useful balance for signal buffers and embedded firmware. For professional audio systems, validate external codec interfaces, clocking architecture, memory bandwidth behavior, and EMI requirements before finalizing the system architecture.
推薦
Networked Embedded Equipment
The STM32H745XIH6 can serve as the central controller in connected industrial, medical, or communications equipment where protocol handling must coexist with real-time processing. Its 46 communication and analog interfaces provide a broad peripheral base, and the dual-core architecture allows network servicing to run while the M7 performs control or DSP work. Up to 2 MB of flash can accommodate networking stacks and application firmware, while 1 MB of RAM supports buffers and protocol state. Keep sensitive communication tasks on a core with dedicated peripheral access, and validate interrupt affinity, DMA contention, and cache-coherency considerations in the final firmware design.
推薦
Motor Drive and Power Control
The STM32H745XIH6 is applicable to sophisticated motor-drive and embedded power-control platforms that combine fast sampling with supervisory functions. The 480 MHz Cortex-M7 can execute current-loop calculations and control algorithms, while the 240 MHz Cortex-M4 can handle monitoring, communications, or fault-management tasks. The family’s 46 communication and analog interfaces provide many possible connections to sensing and power-control circuitry. Safety-critical designs still require redundant measurement paths, watchdog strategy, fault analysis, and appropriate qualification beyond the basic processor specification, so validate those requirements separately.
推薦
Human-Machine Interface Controller
The STM32H745XIH6 can support advanced human-machine interface controllers by assigning graphics, touch processing, and communication to the fast Cortex-M7 while the Cortex-M4 handles independent interface or system tasks. Its 480 MHz processing capability is useful for responsive display updates and complex control logic, and the 1 MB RAM can support display buffers and application data. The 14 x 14 mm TFBGA package enables compact assemblies, although the 240+25 terminal layout requires careful escape routing and inspection. Validate display-controller compatibility, external memory requirements, and pin multiplexing before committing the footprint.

設計說明
Use the exact 240+25 TFBGA land pattern from the STM32H745xI/G family documentation and verify it against the selected PCB stack-up. A 14 x 14 mm package with 265 terminals leaves little routing space, so power and ground connections should follow the manufacturer escape-routing recommendations. Place decoupling capacitors near their associated supply balls and reserve unobstructed access for boundary-scan or X-ray inspection.
Plan the power tree before placing the microcontroller because its high-performance dual-core operation can create fast current transients. Use the manufacturer’s recommended voltage rails, decoupling network, startup sequence, and SMPS configuration where applicable. Confirm the regulator headroom and control-loop behavior across the expected load range rather than relying only on nominal processor frequency.
Although the TFBGA provides a compact footprint, processor activity, internal power conversion, and surrounding circuitry can concentrate heat in the board assembly. Follow the family package thermal data when assigning copper and thermal vias. Avoid placing temperature-sensitive analog circuitry immediately beneath a processor that may operate continuously near its thermal limits, and validate the enclosure temperature and airflow assumptions at system level.
Do not assume that two Cortex-M cores provide identical peripheral instances, clock trees, or interrupt routing. Partition firmware according to the peripheral-sharing rules in the reference manual, enable only the required caches where appropriate, and account for inter-core synchronization and DMA contention. Also verify the exact firmware device identifier before signing production firmware for the STM32H745XIH6 ordering code.
合規資訊
The exact compliance status for this ordering code must be confirmed from the manufacturer product page or current material-declaration documentation. A microcontroller is not automatically qualified for automotive use solely because it belongs to the STM32H7 family.
