180 MHz Cortex-M4 with 2 MB Flash — memory headroom for the GUI-heavy design
The STM32F479AIY6TR: It packs 2 MB of Flash and 384 KB of SRAM, enough to run a full-featured GUI stack, Ethernet + USB host, or a real-time control loop with OTA staging buffers, all without external memory. The 114 I/O lines and rich peripheral set — Ethernet MAC, dual CAN, multiple SPI/I²C, SAI, SDIO, and USB OTG — make it a single-chip fit for industrial HMI panels, networked motor drives, or medical patient monitors that need a display and wired connectivity.
WLCSP package — board area and rework considerations
The 168-ball WLCSP measures 4.89 x 5.69 mm.
STMicroelectronics lists the STM32F479AIY6TR as Active. The base product number STM32F479 covers a range of Flash and package options, so if volume shifts or a different footprint is needed later, a pin-compatible migration within the family is possible without a PCB spin.
