Product details

ARM Cortex-M7 at 216 MHz — what the speed rating means for the BOM

The STM32F746ZGY6TR: 216 MHz core with single-cycle multiply-accumulate and double-precision FPU. 1 MB Flash (1M x 8) and 320K x 8 RAM.

143-ball WLCSP — footprint and assembly considerations

The 114 I/O count includes most of the peripheral pins brought out, so signal routing density is high. This is not a hand-solderable package — rework requires a BGA rework station with a bottom-side preheater and a stencil for the solder balls.

For a human-machine-interface design, the LCD controller plus the SPDIF audio input can drive a touch panel with audio feedback using a single MCU — no external graphics controller or audio codec needed.

Frequently asked questions

What are the alternatives to STM32F746ZGY6TR?

The STM32L151CBU6A is a lower-power ARM Cortex-M3 alternative from the same manufacturer, but it runs at 32 MHz with 32 KB Flash — a different performance tier. For a pin-compatible upgrade path within the STM32F7 family, the STM32F746 line shares the same base number and peripheral set across density options.
