The 32 KB Flash and 12 KB RAM place it in the value-density tier — sized for a single control loop, a CAN gateway node, or a sensor fusion hub, not a multi-threaded HMI. The 2 KB EEPROM holds calibration constants or boot parameters without wearing the Flash.
The 12-channel 12-bit ADC captures analog feedback from current shunts or thermistors without an external converter.
The TM4C1231C3PMI is rated at 80 MHz, with an ARM Cortex-M4F core that includes a single-precision FPU for efficient signal processing.
