Cortex-M4 at 168 MHz — the processing backbone
The STM32F407IGH6TR: ARM Cortex-M4 core at 168 MHz with FPU for DSP tasks; connectivity includes Ethernet, CAN, USB OTG, and DCMI.
Memory headroom and peripheral set
With 1 MB of Flash and 192 KB of SRAM, this MCU can host a full RTOS, TCP/IP stack, and application code without external memory in many designs.
The 176+25 UFBGA (10x10 mm) package is a fine-pitch BGA with 201 balls. The exposed thermal pad on the underside must be stitched to a ground plane with thermal vias to keep junction temperature within limits under continuous load.
