216 MHz ARM Cortex-M7 — what the core speed buys you
The STM32F745IGK6: That core speed, combined with a single-precision FPU and a 6-stage pipeline with branch prediction, puts it in the tier that handles real-time DSP loops, motor-control FOC, or audio codec processing without a separate DSP. The 1 MB Flash and 320 KB RAM are sized for a single OTA-capable firmware image plus a moderate data buffer — think Ethernet-to-CAN gateway, HMI controller with a small frame buffer, or a multi-protocol industrial I/O node.
Peripheral set and connectivity — gateway-class I/O
The 140 I/O lines in the 176+25 UFBGA package give enough headroom to wire a parallel TFT display, an external SRAM/Flash via the EBI, and still leave pins for fieldbus transceivers and sensor interfaces.
Package and supply — BGA layout and voltage range
Housed in a 201-ball UFBGA (176+25 balls, 10×10 mm body), this is a fine-pitch BGA.
For BOM planning, the base product number STM32F745 covers multiple density and package variants, so a second-source within the same family is a pin-compatible drop if the supply situation ever requires it.
