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.","metaTitle":"STM32F746ZET6 STM32F7 MCU, ARM Cortex-M7, 216 MHz","metaDescription":"STMicroelectronics STM32F746ZET6 32-bit ARM Cortex-M7 MCU at 216 MHz with 512KB Flash, 320KB SRAM, 114 I/O, Ethernet, USB OTG, CAN.

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."},{"question":"Does STM32F746ZET6 have Ethernet and USB OTG support?","answer":"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.
