Product details

216 MHz Cortex-M7 — what it buys you on the bus

The STM32F746ZGT6 runs a single-core ARM Cortex-M7 at 216 MHz, which is the top-end clock for this STM32F7 series. That speed, paired with 1 MB of Flash and 320K x 8 of RAM, gives you enough headroom to run a graphical HMI stack, handle Ethernet TCP/IP offload, and still have cycles left for a real-time control loop. The 114 I/O lines in a 144-LQFP package mean you can wire up a parallel LCD, external memory bus, and a handful of sensors without needing a CPLD to expand ports.

Connectivity and peripherals — industrial gateway fit

This MCU carries Ethernet MAC, CAN, USB OTG, multiple SPI/I²C/UART, plus an SPDIF-Rx and SAI for audio. That makes it a natural fit for an industrial gateway or a panel-mount HMI that needs to talk Modbus TCP on one side and a serial sensor bus on the other. The 24-channel 12-bit ADC and dual 12-bit DAC cover analog front-end duties without an external converter.

Lifecycle — EOL hot, plan the BOM move

Lifecycle stage is EOL hot. Base product number STM32F746 remains active across other variants.

Temperature grade and environment

Rated for -40°C to 85°C ambient. Supply range is 1.7 V to 3.6 V.

Frequently asked questions

What is the closest pin-compatible alternative to STM32F746ZGT6?

Within the STM32F7 series, a pin-compatible migration would target another 144-LQFP variant with the same base STM32F746 core, such as the STM32F746ZGT7 or a higher-density STM32F756ZG. Verify the exact Flash/RAM and peripheral set against your firmware image before swapping.

What is STM32F746ZGT6's listed speed?

The core processor runs at 216 MHz, which is the maximum clock for this ARM Cortex-M7 device.

What compliance documentation does ST provide for STM32F746ZGT6?

STMicroelectronics provides RoHS and REACH compliance declarations for the STM32F7 series. The 144-LQFP package is lead-free and RoHS-compliant per ST's standard material declaration. UL or IEC certifications are not listed for this component.
