The TM4C123GH6PMIR is a Texas Instruments Tiva C series 32-bit ARM Cortex-M4F microcontroller running at 80 MHz. The single-precision FPU on the Cortex-M4F core handles real-time math — PID loops, sensor fusion, or FFT — without a separate DSP. 256 KB of Flash and 32 KB of RAM give it room for a moderate control stack plus a bootloader. The 2 KB EEPROM stores calibration constants or fault logs without wearing the Flash. Connectivity covers CANbus for industrial or automotive networks, USB OTG for device/host switching, and multiple serial interfaces (UART, SPI, I²C, SSI, Microwire, IrDA). The 12-bit ADC with 12 channels handles analog feedback from sensors or current shunts.
Rated for -40°C to 85°C ambient, the TM4C123GH6PMIR fits factory-floor controllers, outdoor telecom gear, and engine-bay modules. The 64-LQFP package (10x10 mm) is a common footprint for mid-density MCUs; the 43 I/O are enough for a keypad, display, and a few encoder inputs without needing a port expander.
