The STM32F769AIY6TR is a 32-bit ARM Cortex-M7 MCU from STMicroelectronics' STM32F7 series, clocked at 216 MHz. It packs 2 MB of Flash and 512 KB of RAM, with 129 I/O lines and a rich peripheral set including CANbus, Ethernet, USB OTG, and a TFT LCD controller. The 180-WLCSP (5.5×6 mm) package suits space-constrained designs where board real estate is tight, but demands careful PCB layout and assembly process control for the fine-pitch ball grid.
216 MHz Cortex-M7 — what it buys you
At 216 MHz, the single-core Cortex-M7 delivers enough headroom for real-time control loops, graphics rendering on the internal LCD controller, and protocol stacks (TCP/IP, USB) without a separate host processor. The 512 KB RAM supports double-buffered frame buffers or large data arrays; the 2 MB Flash holds complex firmware with room for OTA update staging. If your application needs less compute, the STM32F7 family scales down in speed and memory — but this part sits at the high end for single-core M7 parts in a WLCSP.
Package and assembly note
180-WLCSP (5.5×6 mm) exposes the die backside. Solder-joint inspection requires X-ray; rework is possible but riskier than with a QFP.
