The TM4C1231H6PZI7 is a Texas Instruments Tiva C Series 32-bit ARM Cortex-M4F microcontroller running at 80 MHz. The single-precision FPU handles real-time math without software emulation — useful for motor-control loops or sensor-fusion algorithms that would otherwise eat MIPS on a Cortex-M3. On the peripheral side, the CAN 2.0B interface targets industrial or automotive body networks where deterministic messaging matters. I²C, SPI, SSI, Microwire, and UART/USART cover sensor aggregation, display links, and debug. The 22-channel 12-bit ADC with 69 GPIOs gives enough analog and digital headroom for a multi-sensor controller or a small HMI panel.
