STM32H747BGT6 Descripción general
A microcontroller (MCU) is a compact integrated circuit that embeds a processor core, memory, and programmable peripherals to govern a specific operation in an embedded system. The STM32H747BGT6 belongs to the high-performance STM32H7 family, which sits at the top of ST's MCU portfolio and offers the highest clock speeds and the most advanced feature set for industrial control, motor control, audio processing, and human-machine interface (HMI) applications. The dual-core heterogeneous architecture combines a Cortex-M7 for high-throughput DSP and graphics tasks with a Cortex-M4 for real-time deterministic control.
Key features include 1 MB of Flash, 1 MB of SRAM, a Chrom-ART hardware graphics accelerator, a hardware cryptographic accelerator, and a rich communication peripheral set including Ethernet, USB, CAN-FD, and multiple I2C, SPI, and UART interfaces. The integrated SMPS step-down converter enables efficient core power regulation from a single 3.3 V rail. An on-board DSI host and TFT-LCD controller support advanced HMI designs.
The STM32H747BGT6 is fabricated on a 40 nm low-power process, supports a 1.62 V to 3.6 V supply range, and operates from -40 °C to +85 °C. The dual-core architecture allows the M7 core to offload real-time tasks to the M4 core, enabling parallel processing across heterogeneous workloads. Hardware isolation mechanisms include an MPU, secure boot, and a true random number generator (TRNG).
Typical applications include industrial automation controllers, motor control and field-oriented-control (FOC) drives, audio processing and effects units, smart-home edge controllers, and high-end consumer electronics with graphical HMI. The rich peripheral set and dual-core architecture make it ideal for complex systems that combine high-speed data processing with deterministic real-time control.
When designing with this device, ensure adequate decoupling on every VDD pin and provide a 4.7 µF bulk capacitor close to the SMPS inductor. Plan PCB thermal dissipation for the LQFP-208 package, and leverage the M4 low-power domain to maximize energy efficiency in battery-powered applications. The package pinout is documented in the ST datasheet referenced below.

Notas de diseño
Estimated: The LQFP-208 package dissipates approximately 0.4 W per MHz at 480 MHz when all peripherals are active, requiring at least 4-layer PCB with a dedicated ground pour beneath the exposed pad area. Provide a 4.7 µF low-ESR ceramic capacitor directly on the VCORE pin (pin 49) and a 1 µF ceramic on each VDD pin, with vias stitched every 5 mm around the chip perimeter. Failure to provide adequate decoupling on the SMPS input (VDD, pin 1) will cause 480 MHz operation to fail due to SMPS ripple coupling into the M7 supply rail.
Estimated: With θJA of approximately 25 °C/W on a 4-layer JEDEC test board, the STM32H747BGT6's junction temperature rises approximately 25 °C above ambient at 1 W dissipation. For motor-control applications where the M7 core runs at full 480 MHz with both ADCs active, total power dissipation can reach 1.5 W (junction rise ~38 °C above ambient), requiring thermal relief through copper pours or active airflow. Industrial designs at 85 °C ambient should derate by ensuring junction temperature remains below 125 °C at full load.
Do not enable the on-chip SMPS without first verifying the external inductor value matches the datasheet recommendation (typically 4.7 µH with low DCR). The SMPS MUST have its own dedicated input capacitor on VDD_SMPS separate from the I/O VDD rail; mixing these causes an unstable 1.2 V core supply and erratic M7 core operation. Also verify pin-strapping of BOOT0 at reset - if BOOT0 is left floating, boot behavior is indeterminate. The device does not require external configuration of the integrated LDO if SMPS is enabled by default in the Option Bytes from factory.
