The TM4C123BH6PGEI is a Texas Instruments Tiva™ C series 32-bit MCU built around an ARM® Cortex®-M4F core running at 80 MHz. That core includes a single-precision floating-point unit, so PID loops, sensor fusion, and filter math execute without software emulation — a real cycle-count saver compared to a straight M3 or M4 without FPU. Program memory is 256 KB of Flash, backed by 32 KB of SRAM and 2 KB of EEPROM for calibration constants or fault logs that survive a reset. On the analog side, the part integrates a 24-channel 12-bit ADC — enough to sample multiple current/voltage/temperature points in a motor drive or power-stage feedback loop without external muxing. The 144-LQFP package gives access to 105 I/O lines, which is generous for a mid-range MCU and suits designs that need parallel display interfaces, multiple encoder inputs, or a wide GPIO bus for memory-mapped peripherals.
Industrial temperature grade — deployment environment
No extended-range screening needed for factory-floor or HVAC-adjacent mounting.
Built-in ADC — channel count and resolution
Yes, the TM4C123BH6PGEI includes a 24-channel 12-bit ADC. That is a single ADC module with a 24-input mux, not 24 independent converters — but for scanning multiple analog signals in a control loop, the muxed architecture is standard and works well with the DMA engine listed in the peripherals block.
