The TM4C1237E6PZIR is a Texas Instruments Tiva C Series 32-bit ARM Cortex-M4F microcontroller running at 80 MHz. The floating-point unit handles single-cycle MAC operations, so sensor fusion, PID loops, and FFTs run in hardware rather than software-emulated. 128 KB of Flash and 32 KB of SRAM are enough for a moderate application with a bootloader and a few hundred lines of control code; the 2 KB EEPROM holds calibration constants or fault logs without wearing the Flash.
