The STM32F746NGH6E is STMicroelectronics' 32-bit ARM Cortex-M7 single-core MCU clocked at 216 MHz, backed by 1 MB of Flash and 320 KB of RAM. The 216-TFBGA package (13x13 mm) keeps the footprint compact but demands a four-layer PCB minimum for BGA fanout.
That means ST is still manufacturing it, and there is no last-time-buy window or obsolescence notice to track. The base product number is STM32F746; if a future redesign needs a different package or memory density, the STM32F7 family offers pin-compatible siblings across the TFBGA and LQFP options.
Peripheral set — Ethernet, CAN, LCD, and more
The connectivity block includes Ethernet MAC (MII/RMII), dual CAN 2.0B, USB OTG HS/FS, six SPI, four I²C, and eight UARTs. The LCD-TFT controller supports up to XGA resolution with a dedicated DMA channel, so the CPU is not stalled during frame refresh.
