480 MHz Cortex-M7 in a 100-ball BGA — what this part delivers
The STM32H742VGH6 is a 32-bit single-core microcontroller from STMicroelectronics' STM32H7 series, built around an ARM Cortex-M7 processor rated for 480 MHz operation.
Peripheral set and connectivity
Connectivity options cover CANbus, EBI/EMI, Ethernet, I²C, IrDA, LINbus, MDIO, MMC/SD/SDIO, QSPI, SAI, SPDIF, SPI, SWPMI, UART/USART, and USB OTG — making it suitable for industrial gateways, motor drives, and human-machine interfaces that need multiple serial buses and a display interface.
Data conversion and supply range
On-chip data converters include a 36-channel 16-bit ADC and a 2-channel 12-bit DAC. The supply voltage range spans 1.62 V to 3.6 V, allowing operation from a single 3.3 V rail or a 1.8 V core supply with I/O at 3.3 V. An internal oscillator is available, though achieving the full 480 MHz core clock requires an external crystal or oscillator feeding the PLL — the internal RC oscillator is typically used for boot and low-power modes.
