That puts it in the sweet spot for control loops that need real-time math — motor FOC, sensor fusion, or digital PSU compensation — without jumping to a DSP or FPGA. The FPU handles trig and divide in hardware; the 256 KB Flash and 32K x 8 RAM give enough headroom for a modest RTOS and a few protocol stacks. 105 I/O pins in a 144-LQFP package mean you can drive a bank of sensors, a parallel LCD, and a CANbus interface without multiplexing. The 20x20 mm footprint is standard for this pin count — no fine-pitch surprises for the assembly house. ## Connectivity and peripherals — what's on the die That covers most industrial fieldbuses and debug links without external transceivers for the digital side. The 24-channel 12-bit ADC samples analog inputs directly — no external mux needed for a multi-sensor array. Internal oscillator and brown-out detect/POR/WDT are built in, so the BOM stays lean: no external crystal needed for non-critical timing, and the watchdog can reset a hung firmware task without a supervisor IC. ## Industrial temperature grade — where it runs Supply range 1.08 V to 3.63 V. ## Lifecycle reality — EOL phase, sourced to order The TM4C1233H6PGEI is flagged as end-of-life (eol_hot). That means TI has issued or will issue a last-time-buy notice. No commitment to long-term production volume without a documented LTB plan.","metaTitle":"TI TM4C1233H6PGEI Tiva C ARM Cortex-M4F MCU, 80MHz","metaDescription":"Texas Instruments TM4C1233H6PGEI 32-bit ARM Cortex-M4F MCU at 80 MHz with 256 KB Flash, 32K x 8 RAM, 105 I/O in 144-LQFP.
