The STM32H742VGT6 is a single-core ARM Cortex-M7 microcontroller from ST's STM32H7 series, clocked at 480 MHz. That core speed puts it in the performance tier for real-time control loops, audio processing, and protocol bridging where you need deterministic throughput without an external DSP. The 1 MB of Flash and 688 KB of RAM give enough headroom for a full RTOS, a TCP/IP stack, and local data logging without external memory — though the EBI/EMI and QSPI interfaces are there if you need more.
Connectivity and peripherals — Ethernet, CAN, USB OTG on one die
This part integrates Ethernet MAC, two CAN interfaces, USB OTG, and a rich set of serial interfaces (SPI, I²C, UART, SAI, SPDIF). For an industrial gateway or a motor-drive node that needs to talk to a PLC over Ethernet and log data over CAN, that means no external MAC/PHY or CAN transceiver — just the physical-layer chips. The 16-bit ADC array (36 channels) and two 12-bit DACs cover analog sensing and control output without an external converter.
Package and temperature — 100-LQFP, industrial grade
Housed in a 100-pin LQFP (14x14 mm), the STM32H742VGT6 is a hand-solderable surface-mount package — no BGA rework needed.
Lifecycle — active, no LTB pressure
That means no last-time-buy clock ticking — it is a safe selection for new production builds and long-life designs. The base number STM32H742 shares the same footprint and peripheral set as the STM32H743, so if you later need more Flash or a second core, the pin-compatible upgrade path is straightforward.
