That clock rate, combined with the single-cycle MAC and hardware divide, puts this MCU squarely in the class that handles a field-oriented motor control loop or a real-time sensor fusion algorithm without needing a separate DSP. The 120 general-purpose I/O lines give you enough headroom for a parallel LCD bus, a bank of encoder inputs, and a CAN node on the same die. ## 256 KB Flash + 32 KB RAM — firmware budget The 2 KB EEPROM stores calibration constants without an external serial EEPROM. ## 157-VFBGA — board-level reality 157-ball VFBGA, Microstar Junior, 9x9 mm body. Requires reflow profile and X-ray inspection. ## Industrial temperature range — where it survives The internal oscillator and POR block keep it running through brown-out events that would reset a commercial-grade part. If your design lives in a conditioned server room, you are paying for temperature headroom you do not need — but for anything with a fan or a heat sink, this is the right grade.","metaTitle":"Texas Instruments TM4C123GH6ZRBT Tiva C MCU, 80 MHz, 256 KB Flash, BGA","metaDescription":"TM4C123GH6ZRBT is a 32-bit ARM Cortex-M4F MCU from TI's Tiva C series. 80 MHz, 256 KB Flash, 32K x 8 RAM, 2K x 8 EEPROM, 157-VFBGA.
