That FPU handles PID coefficients, sensor fusion, or FFT bins without software emulation — a direct cycle save over a Cortex-M3 at the same clock.
The ADC has 22 channels at 12-bit resolution. The 69 GPIOs support parallel interfaces alongside analog inputs.
The base product number is TM4C123.
The core runs at 80 MHz with a single-precision floating-point unit, providing compute headroom for control loops and signal processing.
The TM4C123BH6PZI (256 KB Flash, 32 KB RAM) shares the same 100-LQFP footprint and peripheral set, offering a drop-in upgrade for firmware that needs more program memory. Both are from the Tiva C Series with identical pinout.
Texas Instruments provides RoHS and REACH compliance declarations for this part. The Tape & Reel variant (TM4C123BE6PZI7R) carries the same compliance status as the tray-packed base part.
