The TM4C1230C3PMI7R: 32-bit ARM Cortex-M4F MCU from TI's Tiva C series, clocked at 80 MHz with a single-precision FPU. 32 KB Flash and 12 KB RAM define the value-line envelope.
The 49 I/O lines are mapped through a 64-LQFP package — a 10x10 mm footprint that fits on compact 2-layer boards. CAN is the key for industrial bus nodes; the rest covers sensor and display links. Internal oscillator means no external crystal for basic timing, though a precision clock still helps for CAN bit-timing margin.
