Product details

What this dual-core MCU brings to the board

The STM32H755IIT6 is a 32-bit dual-core microcontroller from the STM32H7 series, pairing an ARM Cortex-M4 at 240 MHz with a Cortex-M7 at 480 MHz. That split lets you run the real-time control loop on the M7 and the communications stack or user interface on the M4 without a second chip. The 2 MB Flash and 1 MB RAM give enough headroom for motor-drive firmware with an Ethernet stack or a multi-protocol gateway application.

Peripheral set and connectivity

Temperature grade and environment

Rated for -40°C to 85°C operating temperature. Supply range is 1.62 V to 3.6 V.
