ARM Cortex-M4F at 80 MHz — what the core clock buys you
The floating-point unit on the M4F core handles single-precision math without software emulation — useful for sensor fusion or motor-current loops where a division or trig step would stall a Cortex-M3. 64 KB of Flash and 24K x 8 of SRAM fit a single-axis servo profile or a CAN gateway node; the 2K x 8 EEPROM stores calibration constants without wearing the Flash. Connectivity includes CAN, USB OTG, I²C, SPI, SSI, and UART, so it bridges between a fieldbus backbone and a local sensor cluster.
