480 MHz Cortex-M7 with 1 MB Flash — what this MCU is for
The STMicroelectronics STM32H743BGT6 is a 32-bit single-core ARM Cortex-M7 microcontroller running at 480 MHz, part of the high-performance STM32H7 family. The part is intended for compute-intensive embedded applications such as industrial motor drives, human-machine interfaces (HMIs), audio processing, and communications gateways where a balance of CPU throughput, memory density, and peripheral integration is needed.
Connectivity and analog integration
The STM32H743BGT6 includes a broad set of serial interfaces: Ethernet, CANbus, USB OTG, multiple SPI and I²C channels, SAI for audio, SPDIF, QSPI, and SDIO. This peripheral count means a single MCU can handle display, sensor, actuator, and network interfaces without external bridging chips.
Housed in a 208-lead LQFP with a 28x28 mm body, the part is a surface-mount device suited for standard reflow assembly. Supply voltage spans 1.62 V to 3.6 V, allowing operation from a single 3.3 V or 1.8 V rail with appropriate regulator margin.
For production BOM lines this means no near-term obsolescence risk.
