Product details

216 MHz ARM Cortex-M7 — what the core clock buys you

The STM32F746ZET6 runs at 216 MHz with a single-cycle multiply-accumulate and hardware FPU.

Peripheral set for industrial connectivity and HMI

This MCU integrates Ethernet MAC, USB OTG (host/device), two CAN interfaces, multiple I²C and SPI buses, plus an SPDIF-Rx interface and a dedicated SAI for audio. The 114 general-purpose I/O lines, spread across a 144-LQFP package (20x20 mm body), give enough pins to connect a parallel TFT display, external SRAM or NOR Flash via the Flexible Memory Controller, and a handful of sensors or actuators without an external GPIO expander.

The base product number STM32F746 covers a family of density and package variants; the ZET6 suffix specifically identifies the 144-LQFP tray version with 512 KB Flash and 320 KB SRAM.

For buyers evaluating a BOM line, the active lifecycle means no supply-chain urgency from discontinuation — the decision rests on price and lead time, which are verified per order.

Frequently asked questions

Is STM32F746ZET6 a good replacement for STM32F745ZET6?

The STM32F746ZET6 is a pin-compatible upgrade from the STM32F745ZET6. Both share the same 144-LQFP footprint and peripheral set, but the F746 runs at 216 MHz versus the F745's lower clock speed and adds the Chrom-ART graphics accelerator and a larger SRAM. For designs that already use the F745, the F746 drops in with no board change and gives extra performance headroom.

Does STM32F746ZET6 have Ethernet and USB OTG support?

Yes, the STM32F746ZET6 includes an Ethernet MAC interface and a USB OTG controller, along with two CAN buses, multiple I²C and SPI ports, and an SPDIF-Rx input. This connectivity set makes it suitable for industrial gateways, HMI panels, and networked control applications without external bridge chips.
