Product details

216 MHz Cortex-M7 with on-chip Ethernet and TFT LCD

The STM32F746ZGT6G is a 32-bit ARM Cortex-M7 MCU from STMicroelectronics' STM32F7 series, clocked at 216 MHz. It carries 1 MB of Flash and 320 KB of RAM, and integrates an Ethernet MAC, a TFT LCD controller, and a full set of connectivity including CAN, USB OTG, SPI, I²C, and SAI. The part is housed in a 144-LQFP package and rated for the -40 to 85 °C industrial temperature range. This combination makes it a fit for HMI panels, industrial gateways, and motor-control applications where a single-chip solution replaces a separate display controller and external Ethernet PHY.

Memory and performance budget

The 216 MHz Cortex-M7 core includes a single-precision FPU and DSP extensions. The 1 MB Flash and 320 KB RAM support GUI and Ethernet applications.

Frequently asked questions

Does STM32F746ZGT6G support Ethernet?

Yes, it integrates a 10/100 Ethernet MAC that connects to an external PHY via RMII or MII. This eliminates the need for a separate Ethernet controller chip in industrial gateway or HMI designs.

What is the closest pin-compatible alternative to STM32F746ZGT6G?

Within the STM32F7 family, the STM32F767ZGT6 and STM32F769ZGT6 share the same 144-LQFP footprint and offer higher clock speeds (216 MHz) with additional cache and memory. Verify the exact pinout against your design before substituting, as peripheral mapping may differ slightly between density variants.

What is STM32F746ZGT6G's listed speed?

The core runs at 216 MHz, which is the maximum clock for the Cortex-M7 in this STM32F7 variant, delivering roughly 1080 DMIPS with single-precision FPU and DSP extensions.
