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. 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. 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.
