Product details

STM32H742BGT6 ARM Cortex-M7 MCU at 480 MHz with 1 MB Flash and 168 I/O in a 208-LQFP package. The 480 MHz core speed means the part can sustain heavy DSP or floating-point workloads — think motor-drive FOC loops, audio processing, or protocol stacks — without stalling the application.

Connectivity and peripheral set

The STM32H742BGT6 includes Ethernet MAC, dual CAN interfaces, USB OTG, and a QSPI interface for external Flash or RAM expansion. The 36-channel 16-bit ADC and dual 12-bit DAC handle analog sensor front-ends directly.

Supply range of 1.62 V to 3.6 V.

Lifecycle and sourcing posture

There is no last-time-buy risk for current or near-term designs.

Frequently asked questions

Does STM32H742BGT6 have Ethernet?

Yes, the STM32H742BGT6 includes an Ethernet MAC interface as part of its connectivity set, along with CAN, USB OTG, and QSPI.

Is STM32H742BGT6 compatible with STM32H743?

The STM32H742BGT6 and STM32H743 are pin-compatible across the same 208-LQFP package and share the same core architecture and peripheral set, with the H743 offering larger Flash and RAM densities. For a direct drop-in with more memory headroom, the H743 is the natural upgrade path.
