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.","metaTitle":"Texas Instruments TM4C123BH6PGEI MCU, ARM Cortex-M4F 80MHz, 256KB Flash, 144-LQF","metaDescription":"TM4C123BH6PGEI Tiva C series 32-bit MCU: 80MHz Cortex-M4F, 256KB Flash, 32KB RAM, 2KB EEPROM, 24-ch 12-bit ADC, -40°C to 85°C, 144-LQFP.
